Hello,

neon says that there's upgrade. Fine. I've click on the icon. Dicover opens and proceed with upgrade. Discover says something about exiting with error 24.
I then run in terminal "sudo apt-get update && sudo apt full-upgrade" to see what errors it gives me. here it is:

----

i did try "sudo apt install --fix-missing" and "sudo apt install --fix-broken" and tried again the upgrade, I still get the errors.

I'm now afraid to reboot in case neon is now in a weird state.

help.
thanks.

hello,

found the solution.
There wasn't enough space on the /boot partition. Made a cleanup as mentionned in ( https://askubuntu.com/questions/1253347 ... -20-04-lts ) and all is good.
