I encounter some troubles with some packages installation. Synaptics package manager offered me to do an upgrade and I accepted it, making my computer freezing at login screen after the reboot (with mouse not moving and so on : really stuck).
During boot, now, I can choose the previous version, before upgrade was applied : this one still work. Or recovery mode, that doesn't seems to end somewhere (I waited one minute only : was I too impatient ?)
Other times, when my computer seems queasy, I attempt a
Ctrl-Alt-1. But I see only a blinking cursor, and no prompt...
I wonder if there is a combination of keys that at the time the computer is booting, forces him to go in console mode, without reaching
GNOME the graphical environment I'm using.
I would like to see if my computer that frozes with the new upgrades when on
GNOME login screen, is however able to start in console mode with all its new packages. And maybe, discover what happened ?
Solution (taken for your advices) : @GADR,
Welcome, Ctrl + Alt + F2 , then sudo dpkg --configure -a then try to update sudo apt update && sudo apt upgrade allowed me to reach the console, pressing that keys immediately after having selected the
22.214.171.124-amd64that were going wrong. But no packages were broken.
apt-get install --reinstall linux-image-126.96.36.199-amd64
succeeded in solving the problem.
Thanks a lot, everyone !
