I wanted to try libreoffice 7, however, the application crashes and it does not open even after running safe mode and restoring the profile This solution I found here.
I am using kubuntu focal fossa.
I want to go back to the previous version, libreoffice 6. I have tried the following solution:
sudo apt-get install ppa-purge && sudo ppa-purge ppa:libreoffice/ppa
But it gave me the following warning:
"PPA to be removed: ppa:libreoffice ppa:libreoffice
Warning: Could not find package list for PPA: ppa:libreoffice ppa:libreoffice"
Can someone help me, please?
