I'm trying to install python3.9.6 on ubuntu
apt only had python3.8
so I tried this https://tecadmin.net/how-to-install-python-3-9-on-ubuntu-18-04/
but it installed python3.9.5,
next, I tried to compile and build python but it didn't install pip so I had to install zlib and spend like 5 days trying to make it work, and it did work and I was able to install both python2.7.18 and 3.9.6 with pip but it didn't install the SSL module so I had to install that and bla bla...
it worked fine after installing openssl but when I tried to install scapy it showed an error message, after some research I found out that the error was caused by outdated SSL module
I figured that compiling and building python had too many problems it didn't installed all the packages for tools like pip.
if I spend some more time I think could fix this but I'm worried that this kind of problem
could happen again in the future,
I'm really desperate, so if you got any ideas please let me know.
1. Update your local repositories
sudo apt update
2. Install supporting software (installing from source requires additional tools)
sudo apt install build-essential zlib1g-dev libncurses5-dev \
libgdbm-dev libnss3-dev libssl-dev libreadline-dev libffi-dev wget
3. Download the latest version of Python Source Code
You might want to do this in a separate directory (like /tmp)
wget https://www.python.org/ftp/python/3.9.6/Python-3.9.6.tgz
4. Extract downloaded files
tar -xf Python-3.9.6.tgz
5. Test system and optimize python
cd Python-3.9.6
./configure --enable-optimizations
This might take a bit of time to complete
6a. Install a second instance of Python (highly recommended)
sudo make altinstall
It is recommended that you use the altinstall method. Your Ubuntu system may have software packages dependent on Python2.x/3.x.
6b. Overwrite default python installation (not recommended!!!)
sudo make install
7. Verify Python installation
python3 --version
# or
python3.6 --version
I am trying to install python 3.6 in ubuntu 16.04 docker image. It was working fine before. But today it is started showing this error.

The error you're getting seems pretty obvious:
This PPA has been removed from public access as part of a protest against the abuse of open-source projects by large companies. For more detail visit the main page here: https://launchpad.net/~jonathonf
The author has removed the PPA you're trying to use. You will need to find another PPA, or install Python yourself from source, or use a different base image. For example, you could use the standard python:3.6 base image if you need Python 3.6 (or just python:3.7 or python:3.8, depending on your needs).
I am trying to install tkinter on Redhat 7.7. I have tried every combination if "sudo yum install [whatever]" and every single time it comes up with "No package [whatever] available".
pip install tkinter
pip3 install tkinter
sudo yum install python3-tkinter
sudo yum install tkinter
sudo yum install python36-tkinter
sudo yum -y install python36u-tkinter
sudo yum -y install python36-tkinter
sudo yum install tkinter
sudo yum install python36-tkinter
sudo yum install python35-tkinter.x86_64
...etc
I have tried to find what repository I might need to enable but RedHat support is all behind a pay wall. What repository do I need to enable?
At this point I am actually considering just switching to Ubuntu as RedHat is giving me all sorts of problems.
EDIT: I tried yum search tkinter and got the following:
Loaded plugins: langpacks, product-id, search-disabled-repos, subscription-
manager
Repo rhel-7-workstation-rpms forced skip_if_unavailable=True due to:
/etc/pki/entitlement/4690243650278863397-key.pem
====================== Matched:tkinter==========================
python3.x86_64 : Interpreter of the Python programming language
I already have python3 installed. I don't know if had I installed via sudo yum install python3.x86_64 vs sudo yum install python3 I would have got different results.
This works for me!
sudo yum search tkinter
sudo yum install python3-tkinter.x86_64
Alright, so I managed to fix this to my satisfaction. What I did is outlined here. First I installed ActiveState's ActiveTcl 8.5, then rebuilt python 3.6 manually by downloading the source using the following:
$: ./configure --with-tcltk-includes='-I/opt/ActiveTcl-8.5/include'
--with-tcltk-libs='/opt/ActiveTcl-8.5/lib/libtcl8.5.so /opt/ActiveTcl-
8.6/lib/libtk8.5.so'
$: make
$: make install
Because I had a couple different versions of Python 3.x, I had to add the following to the .bashrc:
export PYTHONPATH=/usr/local/lib/python36.zip:/usr/local/lib/python3.6:/usr/local/lib/python3.6/lib-dynload:/usr/local/lib/python3.6/site-packages:/usr/local/lib64/python3.6/site-packages
One big issue I ran into was first manually installing Python 3.8 (which came out yesterday) for which there seems to be little support for most packages so far, so be advised. I also had a few system-specific issues with pip.
I tried to install ipython notebook on my OS.But there was an error.How can I solve this?
sudo apt-get install ipython-notebook
Reading package lists... Done
Building dependency tree
Reading state information... Done
Package ipython-notebook is not available, but is referred to by another packag.
This may mean that the package is missing, has been obsoleted, or
is only available from another source
E: Package 'ipython-notebook' has no installation candidate
Do you already have python installed? If so, try:
sudo apt-get install ipython
or if you have pip:
pip install ipython ipython-notebook
Regardless, I instead recommend installing Anaconda or Miniconda from:
https://www.continuum.io/downloads
This will help you setup virtual environments and packages.
I installed ipython via apt, and then went the pip and virtualenvwrapper route for ipython-notebook, which worked for me. The commands were:
sudo apt -y install ipython
mkvirtualenv ipynb
pip install ipython[notebook]
Alternatively:
sudo apt -y install ipython
mkvirtualenv ipynb
pip install ipython[all]
FWIW, I ran into this error when trying to run the following command on a freshly spun up Ubuntu 18 image (on AWS, ami-0ac019f4fcb7cb7e6):
sudo apt-get install ipython3
E: Package 'ipython3' has no installation candidate
Running an apt-get update solved the problem. So:
sudo apt-get update
sudo apt-get install ipython3
Interestingly, I was surprised to find that this particular distro doesn't come with Python 2.7 installed, only Python3. That's probably AWS just trying to keep things light, which I appreciate.
Hopefully this helps someone down the line.
As virtually every Linux distro, Ubuntu comes with Python 2.7 pre-installed. In order to execute your Python code, you open your terminal, cd to the directory where the script is and run python script.py
When I run the following command:
sudo pip install python-ldap
I get this error:
In file included from Modules/LDAPObject.c:9:
Modules/errors.h:8: fatal error: lber.h: No such file or directory
Any ideas how to fix this?
The python-ldap is based on OpenLDAP, so you need to have the development files (headers) in order to compile the Python module. If you're on Ubuntu, the package is called libldap2-dev.
Debian/Ubuntu:
sudo apt-get install libsasl2-dev python-dev libldap2-dev libssl-dev
RedHat/CentOS:
sudo yum install python-devel openldap-devel
To install python-ldap successfully with pip, following development libraries are needed (package names taken from ubuntu environment):
sudo apt-get install -y python-dev libldap2-dev libsasl2-dev libssl-dev
On CentOS/RHEL 6, you need to install:
sudo yum install python-devel
sudo yum install openldap-devel
and yum will also install cyrus-sasl-devel as a dependency. Then you can run:
pip-2.7 install python-ldap
"Don't blindly remove/install software"
In a Ubuntu or Debian based distro, you can use apt-file to find the name of the exact package that includes the missing header file.
# do this once
sudo apt-get install apt-file
sudo apt-file update
$ apt-file search lber.h
libldap2-dev: /usr/include/lber.h
As you could see from the output of apt-file search lber.h, you'd just need to install the package libldap2-dev.
sudo apt-get install libldap2-dev
In Ubuntu it looks like this :
$ sudo apt-get install python-dev libldap2-dev libsasl2-dev libssl-dev
$ sudo pip install python-ldap
Windows: I completely agree with the accepted answer, but digging through the comments took a while to get to the meat of what I needed. I ran across this specific problem with Reviewboard on Windows using the Bitnami. To give an answer for windows then, I used this link mentioned in the comments:
http://www.lfd.uci.edu/~gohlke/pythonlibs/#python-ldap
placed that wheel (whl file) into my reviewboard install directory
Then, executed the following commands
easy_install pip
pip install python_ldap-2.4.20-cp27-none_win32.whl
(because I had python 2.7 and a 32bit install at that)
easy_install python-ldap
For those having the same issue of missing Iber.h on Alpine Linux, in a docker image that you are trying to adapt to Alpine for instance.
The package you are looking for is: openldap-dev
So run
apk add openldap-dev
Available from version 3.3 up to Edge
Available for both armhf and x86_64 Architectures.
On Fedora 22, you need to do this instead:
sudo dnf install python-devel
sudo dnf install openldap-devel
On openSUSE you need to install the packages openldap2-devel, cyrus-sasl-devel, python-devel and libopenssl-devel.
zypper install openldap2-devel cyrus-sasl-devel python-devel libopenssl-devel
python3 does not support python-ldap. Rather to install ldap3.
For alpine docker
apk add openldap-dev
if the python version is 3 and above try
pip install python3-ldap
I had problems with the installation on Windows, so one of the solutions is to install the ldap package manually.
A few steps:
Go to the page pyldap or/and python-ldap and download the latest version *whl.
Open a console then cd to where you've downloaded your file like some-package.whl and use:
pip install some-package.whl
The current version for pyldap is 2.4.45. On a concrete example the installation would be:
pip install .\pyldap-2.4.45-cp37-cp37m-win_amd64.whl
# or
pip install .\python_ldap‑3.3.1‑cp39‑cp39‑win_amd64.whl
Output:
Installing collected packages: pyldap
Successfully installed pyldap-2.4.45
EDIT
You can install the proper version for Python-3.X though using following command:
# if pip3 is the default pip alias for python-3
pip3 install python3-ldap
# otherwise
pip install python3-ldap
Also here is the link of PiPy package for further information: python3-ldap 0.9.8.4
OR
ldap3 is a strictly RFC 4510 conforming LDAP V3 pure Python client library. The same codebase runs in Python 2, Python 3, PyPy and PyPy3: https://github.com/cannatag/ldap3
pip install ldap3
from ldap3 import Server, Connection, SAFE_SYNC
server = Server('my_server')
conn = Connection(server, 'my_user', 'my_password', client_strategy=SAFE_SYNC, auto_bind=True)
status, result, response, _ = conn.search('o=test', '(objectclass=*)')
# usually you don't need the original request (4th element of the returned tuple)
For most systems, the build requirements are now mentioned in python-ldap's documentation, in the "Installing" section.
If anything is missing for your system (or your system is missing entirely), please let maintainer know!
(As of 2018, I am the maintainer, so a comment here should be enough. Or you can send a pull request or mail.)
To correct the error due to dependencies to install the python-ldap : Windows 7/10
download the whl file
http://www.lfd.uci.edu/~gohlke/pythonlibs/#python-ldap.
python 3.6 suit with
python_ldap-3.2.0-cp36-cp36m-win_amd64.whl
Deploy the file in :
c:\python36\Scripts\
install it with
python -m pip install python_ldap-3.2.0-cp36-cp36m-win_amd64.whl
sudo apt-get install build-essential python3-dev python2.7-dev libldap2-dev libsasl2-dev slapd ldap-utils python-tox lcov valgrind
Debian Reference :

For others: https://www.python-ldap.org/en/latest/installing.html
On OSX, you need the xcode CLI tools. Just open a terminal and run:
xcode-select --install
For ArchLinux/Manjaro for me helped the following command:
yay libldap24
As of december 2021 there was/is a strange problem with the ldap library (at least in arch/manjaro).
While installing python-ldap (at 'Building wheel for python-ldap') I got the message 'ERROR: Failed building wheel for python-ldap':
/usr/bin/ld: cannot find -lldap_r
collect2: error: ld returned 1 exit status
error: command '/usr/bin/gcc' failed with exit code 1
a workaround is provided here: https://github.com/python-ldap/python-ldap/issues/432#issuecomment-974799221
I cite:
As a workaround create the file /usr/lib64/libldap_r.so with content
INPUT ( libldap.so ). The approach works on all systems that use a GNU
ld-compatible linker.
# cat > /usr/lib64/libldap_r.so << EOF
INPUT ( libldap.so )
EOF
In FreeBSD 11:
pkg install openldap-client # for lber.h
pkg install cyrus-sasl # if you need sasl.h
pip install python-ldap
As a general solution to install Python packages with binary dependencies [1] on Debian/Ubuntu:
sudo apt-get build-dep python-ldap
# installs system dependencies (but not the package itself)
pew workon my_virtualenv # enter your virtualenv
pip install python-ldap
You'll have to check the name of your Python package on Ubuntu versus PyPI. In this case they're the same.
Obviously doesn't work if the Python package is not in the Ubuntu repos.
[1] I learnt this trick when trying to pip install matplotlib on Ubuntu.
If you're working with windows machines, you can find 'python-ldap' wheel in this Link and then you can install it
for those who are using alphine linux,
apk add openldap-dev
try:
ARCHFLAGS="-arch x86_64" pip3 install python-ldap
Adding also libzbar-dev solved for me the installation of python-ldap when building DOCKER
The full command becomes:
apt-get install -y python-dev libldap2-dev libsasl2-dev libssl-dev libzbar-dev
A hack answer for FreeBSD 13.1 (yes, I know this is deep South of best practices, but I just needed a quick fix):
pkg install openldap24-client
cd /usr/local/include/python3.9
ln -s ../<all of the below> .
lber.h
lber_types.h
ldap.h
ldap_cdefs.h
ldap_features.h
ldap_schema.h
ldap_utf8.h
openldap.h
sasl
pip install python-ldap
