Hello!

I try to use "Add/remove Applications" on the home menu, but I get a dialog box with following:

Failed to check for installed and available applications

Further it says that I must check the file /etc/apt/sources.lit

But what shall I do exactly?
Thanks for answering

Hello
Update and upgrade your repositories: sudo apt update && sudo apt upgrade then try again...
Remember that you don't need any gui installer for install softwares.
just try: sudo apt install [softwarename] in your terminal.

Thank you again!
You have solved two of my problems today (this and that https://trisquel.info/en/forum/installing-playsound-python3)
I tried sudo apt update. It appeared that I had put a corrupt file in a directory. I took the file away.
Then tried again your suggested commands and now everything work.
And yes I prefer also to use sudo apt instead of gui.
Thanks again :)
