apt - dpkg python-rpi.gpio dependency problems

Every time i try to install something, upgrade or autoremove this error happens!
I've searched the web and tried some fixes but they don't seem to work, I don't have python2.7 installed only 3 and can't install python2 or anything because of this. I've tryed to sudo rm python-rpi.gpio_0.7.0-0.1~bpo10+4_armhf.deb but the file will keep comming. Pls I really need some help since I've got some work on my pi and don't want to get a new image

Some notes: I really really don't want to change the SD Card and parcially lose what I have, second I've tried sudo apt-get install -f and sudo apt update --fix-missing when i followed this guide the sudo dpkg --remove --force-remove --reinstreq command was showing this error dpkg: error: unknown force/refuse option 'remove'

As it turns out I still had remainnings of Python2 and Python3 binaries and those were not linked properly by the OS, this means that Python3 was linked to Python2 and vice-versa.
To get it working I had to:
Uninstall the Python2 dependencies
Get the link working correctly
Reinstall Python2 with wget
Verify if all links are working correctly (for Raspbian this means):
python --version links to Python2
python2 --version links to Python2
python3 --version links to Python3

Use the following commands:
sudo dpkg -i --force-overwrite /var/cache/apt/archives//python-rpi.gpio_0.7.0-0.1~bpo10+4_armhf.deb
Still have the same problem, use:
sudo mv /var/lib/dpkg/info/python-rpi.gpio.* /tmp/
sudo dpkg --remove --force-remove-reinstreq python-rpi.gpio
A typo in your command sudo dpkg --remove --force-remove --reinstreq isn't valide. The correct option is --force-remove-reinstreq. See dpkg --force-help.

Unable to install box2d

I run this command:
apt-get install python-box2d
and I get the following output:
E: Could not open lock file /var/lib/dpkg/lock - open (13: Permission denied)
E: Unable to lock the administration directory (/var/lib/dpkg/), are you root?

Always prefix sudo before executing any installation related command no matter if it's pip or aptik, it tells the terminal that you have the authority to make this change (installation).
For example:
sudo apt-get update
It's for updating your repository , and so it needs to be authorized to get executed.
Also sometimes this error occurs when some other installation is in progress and it has locked the main directory , So you just have to wait for that process or installation to get completed.

Elasticsearch Errors while doing any operation with system?

I have installed Elasticsearch and now due to some changes done by other folks at my work place some errors keep on popping up during any operation like update, install a new package and also the elasticsearch is not working properly.
Error Log is attached for installing new package.

Any one with suggestions on how to solve this issue?
Also this command gives nothing
$ systemctl status systemd-sysctl.service
Failed to get properties: No such interface ''

is systemd your init service in this installation? Also what linux distribution is this? Which version of your distribution? I am currently thinking that you might not be using systemd, but the elasticsearch package is assuming this somehow.
I'd highly appreciate if you open up a bug report in the elasticsearch repository with all of the above information, this warrants more research on the ES side (disclaimer: I'm an ES developer and keen to get this fixed :-).
Also: You can try to remove the elasticsearch package completely by running dpkg -P elasticsearch.
And in addition you can try to add set -x to /var/lib/dpkg/info/elasticsearch.postinst and run sh /var/lib/dpkg/info/elasticsearch.postinst configure
to get more debugging output

I had quite the same problem.
It is obiviously related to systemctl, not elasticsearch.
First you have to determine if u are using it.
[[ `systemctl` =~ -\.mount ]] && echo yes || echo no
In my case, the answer was "no"
So you have to enable it.

how to remove entirely the python directory?

Please help me to resolve this issue about the removing of the python directory. There is the stack trace of my bug when I try to remove the python directory using the following command apt-get autoremove python
ImportError: No module named debpython
dpkg: error processing python-pkg-resources (--remove):
subprocess installed pre-removal script returned error exit status 1
Removing python-psutil ...
Traceback (most recent call last):
File "/usr/sbin/update-python-modules", line 16, in <module>
Processing was halted because there were too many errors.
E: Sub-process /usr/bin/dpkg returned an error code (1)

have you tried
sudo apt-get purge *your-program-name*
this will totally (well... almost) delete your program and its library(ies)
Hope this helps

Well, I find the solution and it's works for me when I use the following command:
$ pip uninstall python

datastax opscenter installation failed with 'no such option: --post-install' error

Background:
I have a 3 node cassandra (1.2.5) cluster and I am trying to install datastax on one of the nodes. I am following instructions from: http://www.datastax.com/docs/opscenter/install/install_deb
I have following already installed:
java -version = 1.6.0_24
python -V = 2.6.6
openssl version = 0.9.8g 19 Oct 2007
Issue:
When I run 'sudo apt-get install opscenter-free', the installation starts but errors out with:
update-python-modules: error: no such option: --post-install
dpkg: error processing opscenter-free (--configure):
subprocess post-installation script returned error exit status 2
Possible root cause:
By searching for error I could gather it looks like python issue.
I ran ls to see where python resides, here some results:
ls /usr/local/bin = python python2.6 python2.7
ls /usr/bin/ = python python2.5
As specified before if I run 'python -V' result is 2.6.6.
I don't understand how to make my opscenter installer to look at the appropriate version?
or how to understand which python it is referring to?

This is most likely an issue with the following from the opscenter-free package:
# cause any deferred python module compilation (like for telephus) to be done
# now, before the initscript starts
if which update-python-modules >/dev/null 2>&1; then
update-python-modules --post-install
fi
update-python-modules comes with the python-support package. It looks like the binary is available, but whatever version the install process is finding doesn't recognize the --post-install option.
If which update-python-modules points to an older (<= 2.5) or newer (3.0+) version of the script, you can try removing whatever package is including that, or updating the python-support package.
