over period of time, very long list in sources.list. there are very few packages installed, required, used by me. i want to remove as many as possible from file. i just want to install latest stable versions and focal, focal-updates and focal-backports satisfy my needs. should i delete all others? my only concern, why mupdf is not uptodate?
sources.list:
Code:
jindam@localhost:~$ cat /etc/apt/sources.list
