error that says not enough space on boot

sudo apt-get -f autoremove

results in

0 upgraded, 0 newly installed, 0 to remove and 100 not upgraded.

I've manually removed all kernels (with sudo rm on /boot) except for 5.14.0-1033-oem that I've got from uname -a. This solved lack of space problem for a little bit, so I could run autoremove, and fix-broken (previously they were failing due to lack of space on /boot). But those commands brought a lot of kernels back and there is no space on boot again.

My previous post 0 bytes left on /boot, apt autoremove and apt --fix-broken install fail due to unmet dependencies was marked as answered in My /boot partition hit 100% and now I can't upgrade. Can't remove old kernels to make room , but in fact I've done everything from the linked answers just to come back to original situation.

    Ubuntu automatically removes and deletes superseded kernels to free up space in /boot, so something else is wrong with your system if that automatic mechanism is not working. – user535733 May 25 '22 at 15:10

Ok, the answer was for me to do the whole exercise again.

To sum up the whole story:

  • first rm from boot every kernel related file, except for the one from uname -a
  • sudo apt autoremove , sudo apt --fix-broken install , sudo apt clean
  • now /boot is almost full again, because --fix-broken has put a lot of kernel files in /boot
  • again remove every kernel but uname -a
  • now I'm cool and I can run software updater without errors

This is a little bit counterintuitive but it worked.

    You are describing brute-force methods that are not required. Instead, use ls to learn the kernels that are installed. Use dpkg to uninstall one of those extra kernel packages by name (it can do that, even if the partition is full).. Then use apt to uninstall the rest of the extra kernel packages by name (easier than using dpkg). Then apt autoremove and apt autoclean to tidy up. No need for rm. No need for --fix-broken-install. – user535733 May 25 '22 at 15:09
