I had a problem with my left audio front panel and I was trying to fix it. I searched for a solution for my problem in other sites and I execute a code to eliminate the pulse folder. However, the system settings and the control volume are missing now. I try to install gnome and pavucontrol
. But the system returns the same message:
$ sudo apt-get install pavucontrol
Unable to fetch some archives, maybe run apt-get update or try with --fix-missing
P.S. My Ubuntu is 17.10
