@brennor when checking for available updates via tab on top,aswell as when searching for packages through search menu,infinity loop gets displayed.how can it be resolved,so that software center can be used,as supposed to?
I’m not sure, I don’t use the software center at all. How long have you let it run for? It is possible that there is just a bunch of processing going on to update after removing the cdrom sources list.
You might find some additional information in /var/log/apt/term.log. Watching that log file while launching the software center might provide additional insight.
tail -f /var/log/apt/term.log
when triggered via terminal,logfile is ending,before the center can even be launched.
so,how can that log file be watched,while the software center is launching?
using a -F instead of -f will follow the log file even if it is truncated or rotated.
