I just ran sudo apt-get update && sudo apt-get upgrade
and suddenly there was no sound.
I rebooted and I heard the bios boot sound but when Ubuntu boots there is no sound. I followed instructions on this post but when I uninstall alsa-base
I couldn't install it back and apt
says there is no install candidate :
Package alsa-base is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source
E: Package 'alsa-base' has no installation candidate
I tried to do this but it doesn't work, apt
just gets 404 on that repo.
Now I can't even get to the System settings page since alsa-base
was uninstalled.
Any suggestions?
