I am afraid that I don’t have good news for you.
Your root partition (/dev/sda3) has only 69M space left. The chances are virtually certain that new package updates will exceed that. Unfortunately what is in the root partition is all related to the packages and can not easily be removed. All the logs are stored in the /var partition (/dev/sda4), which is the partition with lots of space.
You additionally have very little space left in your /boot partition (/dev/sda1) and it is clear that 64M is insufficient for updating with the current kernel, etc. You would need 128M otherwise even if the update in the root partition could be made when you went to reboot it would fail.
The only ways to resolve this are
- Do a fresh install and then restore
- Move space on the /var partition to the /boot and / partitions. However that can only be done when the partitions are not mounted, so cannot be done while IPFire is running.
I am afraid that your simplest option will be to re-install when you are no longer remote from the IPFire location and then do a restore from your last backup.
