Unmet dependencies

[Melu]

Hello everybody,
time ago I made a mess with kernels, triyng to remove old installations. I have an encrypted laptop, Linux Mint 18.33 Cinnamon 64-bit. I can't install anything any more, nor make updates. I asked this problem to the Italian forum but they couldn't solve it. Now:

Time to remove some of your old kernels that you are not using anymore.

time ago I made a mess with kernels, triyng to remove old installations. I have an encrypted laptop, Linux Mint 18.33 Cinnamon 64-bit. I can't install anything any more, nor make updates.

Your problem is the full /boot partition. Run this in a terminal (copy & paste as a whole):

Code: Select all

dpkg-query -W -f '${Version}\n' 'linux-image-[^g]*'|sort -u|sed -e '/^$/d' -e 's/\~[^~]*$//' -e 's/\.[^.]*$//' -e "/$(uname -r|sed s/-generic//)/d" -e 's/.*/sudo rm -rfv \/boot\/*-&-*/'|source /dev/stdin

This will delete a bunch of files from that partition. Then run this:

Code: Select all

sudo apt-get install -f -y
sudo apt-get autoremove --purge -y
sudo update-grub

and finally this:

Code: Select all

dpkg-query -W -f '${Version}\n' 'linux-image-[^g]*'|sort -u|sed -e '/^$/d' -e 's/\~[^~]*$//' -e 's/\.[^.]*$//' -e "/$(uname -r|sed 's/-generic//')/d" -e 's/.*/linux-*-&*/'|tr '\n' ' '|xargs -r sudo apt-get remove --purge -y

If that last one generates errors please post them here, I don't need to see them for the previous commands. Otherwise you'll be all good after that. All kernels except your current one will have been removed.

removed.

This worked! Amazing. I was able to make all the updates. Thank you so much!
