So Im studying an odoo course in udemy. But I cant install the dependencies.
Im using ubuntu 20.04

Try running following commands:

sudo apt-get update
sudo apt-get install python-cups python-dateutil python-decorator python-docutils python-feedparser
You Have to download the correct dependencies for odoo based on your ubuntu version.
Dependencies for ubuntu 20.04 are here:

I am currently trying to install libpq-dev to install psycopg2. The problem is, when I try to install it, an error occurs saying I don't have the latest libpq5 version. However when I try to download the newer version of libpq5 the system says that I already have the latest version. An example of the error.

The following information may help to resolve the situation:

libpq5 is already the newest version (12.4-1.pgdg20.04+1).
0 upgraded, 0 newly installed, 0 to remove and 4 not upgraded.
As of late January 2023 the command is:
sudo apt-get install libpq5=12.12-0ubuntu0.20.04.1 && sudo apt-get install libpq-dev
When you're using Ubuntu 22.04 try:
sudo apt-get install libpq5=14.5-0ubuntu0.22.04.1 && sudo apt-get install libpq-dev
Any newer version of libpq5 can cause this error. In my case it was libpq5=13.1-1.pgdg20.04+1.
It's the similar answer as furus has given but the change is it's libpq5 in ubuntu 20.04 (atleast in my case).
I fixed the issue by installing
sudo apt-get install libpq5=12.5-0ubuntu0.20.04.1
and then install liqpq-dev again
sudo apt-get install libpq-dev
I would say you have installed the latest libpq (12.4-1) but libpq-dev needs older version (12.4-0) and this makes problem.
You may try to install older libpq
apt-get install libpq==12.4-0ubuntu0.20.04.1
but if other program uses the latest version then older version can make problem with this program.
pgdg20 in 12.4-1.pgdg20.04+1 means it is not module from standard ubuntu repo but from some other repo - probably postgresql repo - and maybe this repo has also the latest version libpq-dev. You would search 12.4-1.pgdg20.04+1 in Google and maybe you could find also libpg-dev with 12.4-1.pgdg20.04+1
I found libpq-dev 12.4-1.pgdg20.04+1 and you can download .deb file and install it.
Or you can add this postgresql repo and install with apt-get. This method will also inform about updates and then you could install updates automatically.
This worked for me:
sudo apt-get install libpq5=12.7-0ubuntu0.20.04.1
if you are trying to install it on Ubuntu 20.04 then run below command to install libpq-dev
Command1: sudo apt-get install libpq5=12.2-4
Command2:
sudo apt install libpq-dev
Link: https://ubuntu.pkgs.org/20.04/ubuntu-main-arm64/libpq-dev_12.2-4_arm64.deb.html
What worked in my case was.
sudo apt-get install libpq5=14.5-0ubuntu0.22.04.1
The libpq5 package that worked for me corresponds to my version of ubuntu I found it at:
https://pkgs.org/download/libpq-dev
For ubuntu version 22.04.1
Then I was able to use sudo apt-get install libpq-dev without problems.
I had to download this package and run
sudo dpkg -i ~/Downloads/libpq-dev_13.3-1.pgdg20.04+1_amd64.deb
I have the same problem when I install psycopg2-binary, It seems like it is caused by repository conflict.
In software & Updates => other software
Unselect https://ftp.postgresql.org/pub/pgadmin/pgadmin4/apt/focal.
sudo apt-get remove libpg5
sudo apt-get install libpg5 libpg-dev
Solved my problem
This problem persists in 22.04:
Os pacotes a seguir têm dependências desencontradas:
libpq-dev : Depende: libpq5 (= 14.3-0ubuntu0.22.04.1) mas 14.4-1.pgdg22.04+1 está para ser instalado
I had to revert libpq5 as per the error message above:
sudo apt-get install libpq5=14.3-0ubuntu0.22.04.1
I think this is because your libpg-dev is depending on libpg5=12.4-0ubuntu0.20.04.1 but 12.4-1.pgdg20.04+1 is to be installed in your machine that is why the error occurs when you sudo apt-get install libpg-dev.
Therefore you can try sudo apt-get install libpg5=12.4-0ubuntu0.20.04.1 first,
after that, sudo apt-get install libpg-dev.
I did this way to solve my problem which was similar to yours.
Update package worked for me:
sudo apt update
sudo apt install libpg-dev
You can find the latest version here.
https://packages.ubuntu.com/bionic/libpq-dev
The only solution that worked for me is
sudo apt-get install libpq5=14.5-0ubuntu0.22.04.1
sudo apt-get install libpq-dev
then
pip install psycopg2
Yes, upvote when this works for you.
Good luck.
This issue was fixed in pgadmin repo: it now provides a matching version of libpq-dev along with libpq5. You can update both packages to the latest version and remove pins (unless there is yet another flawed provider of the libpq5 package in your apt sources).

This error can be caused by an incomplete package installation.
Try:

Then run the install command again.
sudo apt-get install python3-pip
This is the command I used to install python-pip
sudo apt-get install python-pip
I get the following error

I already installed the latest version of python-dev

Explain me how to resolve the error and guide me the steps to get python-pip installed.
got the same error when I install python-pip, the following command solved my problem.
sudo apt-get install python-pkg-resources=3.3-1ubuntu1
sudo apt-get install python-setuptools
download pip from https://bootstrap.pypa.io/get-pip.py
Then run the following (which may require administrator access):
python get-pip.py
This should get you going.
If you get stuck again, read here: http://pip.readthedocs.org/en/stable/installing/
In addition to the solution that #seems recommended, I had to run this.
apt-get update
(OR)
sudo apt-get install python-setuptools python-dev build-essential
sudo easy_install pip
i have the same issue, and eventually i gave up by using:
sudo apt-get install python-pip
after tryings something like:
sudo apt-get install python-setuptools python-dev build-essential
but with no luck.
So all i did then was to:
curl https://bootstrap.pypa.io/get-pip.py -o get-pip.py
python get-pip.py
peace of mind.....
I think you should try:
sudo apt-get install python-pkg-resources=3.3-1ubuntu1
And then:
sudo apt-get install python-pip python-dev build-essential
It will definitely solve your issue.
Jut run this command :
sudo apt-get update
than install python tools :
sudo apt-get install python-pip
sudo apt-get install python-dev
sudo apt-get install build-essential
All the packages will get installed or some of them may say its already latest version, Thats fine
