Hello,
I decided to upgrade my Debian Stable (Buster) system today using instructions on the Internet.
I booted into Mate. The first bad thing was no speech. I remembered being asked if I wanted to update my /etc speech dispatcher files. I said "yes" because /etc is system settings, right? I forgot speech runs system wide.
Next was to fix that problem by just reinstating MATE, but now the second problem: no networking. I rebooted to use a USB rescue disk.
I had to use a Ubuntu rescue disk because both my Ethernet and Wi-Fi cards contain non-firmware.
I did a chroot having mounted my broken Debian system at /media/debian.
My updates seemed OK, but reinstalling didn't seem to work because they were done in seconds.
Is there a method of fixing a broken Debian Bullseye system on the latest release candidate CD?
Best wishes
David
