I am trying to install an application and as mentioned in the manual, I am trying to add it's repository without luck:
sudo add-apt-repository ppa:linuxuprising/shutter
And here is the error I am getting:
Traceback (most recent call last):
File "/usr/bin/add-apt-repository", line 12, in <module>
from softwareproperties.SoftwareProperties import SoftwareProperties, shortcut_handler
File "/usr/lib/python3/dist-packages/softwareproperties/SoftwareProperties.py", line 28, in <module>
import apt_pkg
ModuleNotFoundError: No module named 'apt_pkg'
I have tried to reinstall using this solution:
sudo apt remove python3-apt
sudo apt autoremove
sudo apt autoclean
sudo apt install python3-apt
Still get the same error on my Ubuntu 20.04 LTS Python version is: 3.7.9
I must say that it work when I switch to python 3.8 using update-alternatives.
Maybe this can help you to guide me what should I change.
You can add the repository manually (working around the add-apt-repository script problem):
Import the gpg key:
sudo apt-key adv --recv-keys --keyserver keyserver.ubuntu.com EA8CACC073C3DB2A
Add the ppa:
printf "%s\n" "deb http://ppa.launchpad.net/linuxuprising/shutter/ubuntu focal main" |\
sudo tee /etc/apt/sources.list.d/linuxuprising-shutter-focal.list
Then run:
sudo apt update
