Gnome-Software apt lock error

My software center is really buggy and creates a lot of problems in Zorin OS. It gets stuck and keep giving strange errors which I can't understand. So, I thought of reinstalling Software Center through Terminal to fix problems but this happened

Pls Help

You must close Synaptic Package Manager, then run the terminal command. Apt can only manage One Package Management at a time.

Once done, please also run the following command in terminal:

sudo apt install --reinstall ca-certificates

Thank you for providing solution so fast. And sorry for using wrong tags as I'm new on Zorin Forum and don't have ideas of tags and all the stuff.

Thank you,
Have a nice day ahead.


No problem, fixing things is what we do. :wink:


I've another Question, I have been reading many complaints about Software Center to be buggy and stuff, so why Developers are not fixing this issue of Software Center and remove all the Bugs from Software Center?
And I have uninstalled Telegram as it was causing problems in my System but still, I'am seeing it's update in update tab, what show I do?

The Software store is developed by Gnome, not by the ZorinGroup.

ZorinGroup included Gnome-Software as it most resembles Windows Microsoft Store.
But yes... Gnome-software is quite buggy. You can help by filling out Bug Reports with Gnome Developers to alert them to issues with the application.

Many of us prefer Synaptic, which I see you have installed already.

You might open Synaptic and search
Then remove any remaining Telegram application files.


Cursed Gnome strikes again....
