Good morning,

I have KDE for 6 months on a Lenovo laptop (dual boot kept with Windows).

This morning by downloading a software (kolourpaint) the computer refused to launch it and then no button worked, I had to press the button to force the shutdown.

Restarting didn't work, Linux started but then unable to access my profile.

I tried safe mode trying to fix things, no more. Then I did

"CTRL + ALT + F2 to activate a text session. enter the login and password.
- run the following commands in order:

sudo pkcon refresh
sudo pkcon update
sudo reboot"

Updated muse stuck at 85% and then strictly unable to restart, black screen stuck at "unable to mount root"

Is there a thing to do or is it hopeless? Was there an error on my part (I was just trying to download image editing software!)?

I still have the key to reinstall but first I would like to understand so that it doesn't happen again.

Sincerely, Wang

The last error sounds like a kernel issue. Can you boot into safe mode again? If that is possible run your pkcon update commands again.

Also which edition are using (user, testing?) As that can explain different problems?

Thank you. It seems I cannot anymore boot in safe mode but I will try tomorow again. I am using "user".

It still doesn't work, I cannot do nothin, the last error when i tried to boot was "SGX disabled by bios"

Literally the first google search result.

Yes thanks. But it was saturday moning, I would try if I could.

Now I have the message "end kernel panic - not syncing : VFS unable to mount root fs on unknown bloc (0,0)"

there is something wrong with your drive mounting - https://unix.stackexchange.com/question ... n-block0-0
