Hello,This afternoon I have done an upgrade on my Trisquel 8 system, because some packages were not updated. I shut down my computer before I finished working. Now I need to work on it but I am having some troubles:
- I lost the sound- I am unable to open the "Sound" application from the Control Center (nothing is happening: no windows).
Is it possible to revert those upgrades which were done this afternoon? how may we do it?
Thank you for your kind support.
