I need help urgently :(

I was trying to update my Python and messed up my whole system.

I am currently now able to start my software centre. I tried Googling multiple fixes but nothing helped. My Software Centre can't start.

When i try starting it up, this error shows :

astephen@localhost:/usr/bin$ ./software-centerGtk-Message: Failed to load module "gtk-vector-screenshot"

Traceback (most recent call last):

File "./software-center", line 36, in <module>

from softwarecenter.utils import (

File "/usr/share/software-center/softwarecenter/utils.py", line 19, in <module>

import dbus

ImportError: No module named dbus

I tried reinstaling dbus using

 apt-get install --reinstall dbus 

but it did not help :(

Any help is appreciated :(

A quick search reveals that the name of the Debian package for the Python DBUS module is called python-dbus (or python3-dbus). Why it isn't available despite being an explicit dependency of the software-center package is beyond me. You should re-install the two packages in case they were corrupted:

sudo apt-get install --reinstall software-center python-dbus

i tried to run sudo -h pip install dbus however it returned : Could not find a version that satisfies the requirement dbus (from versions: ) No matching distribution found for dbus Any ideas ? :( –

Further information on what you did would be helpful, however, my hunches:

Consider a python3 upgrade issue

When upgrading to python3, the modules sometimes change names / the import procedure changes; did you remove your old python environment manually or installed something from git?

Try aptitude

Install aptitude, it recommends ways to solve dependencies. Be careful, however, always check what it wants to do, which other stuff may be affected by this change, and write down what you do, and what aptitude does so you always can undo possible missteps.

Reinstall your System

Sometimes it's just best to nuke everything (in a convoluted OS error issue, after backing up everything, using the export function of the apps apps you want to backup, preferrably. That makes things way easier).

If your python3 module cannot find the right version of packages, a possible hack is to create symlinks to old versions.
In case of dbus, you can do the following. (Say you just upgrade python3.5 to python3.6)

$ cd /usr/lib/python3/dist-packages/
$ ln -s _dbus_glib_bindings.cpython-{35m,36m}-x86_64-linux-gnu.so


If you get further errors, try to link all packages.

a=$(find /usr/lib/python3/dist-packages -name '*35m*so')

b=$(echo $a | tr 35m 36m)

IFS=' ' read -r -a a <<< $a

IFS=' ' read -r -a b <<< $b



for ((i=0;i<${#a[@]};++i)); do

    ln -s "${a[i]}" "${b[i]}"

done

You must install dbus-python package using pip or pip3:

pip3 install dbus-python

or

pip install dbus-python

Might be you need to sudo before the above commands.
