Not enough space in boot partision for update

Sebastian

I have a separate partision for /boot. It has the standard size of a normal Ubuntu installation (700+ MB). There are only the latest two kernel versions installed but 50%+ of the space is taken and I can't install the new update from 21.04 to 21.10. I could delete the second kernel but that would only be a temporary fix. I have searched a lot but the solution was always to "delete the dozent old kernel versions". I only have the one I'm using and the backup kernel. Are there other known ways to free up space that I cound'nt find.

Your initrd images seem to be 3x the size they are on my system. That's what's taking up all the room, no idea how that happened.

PC or Laptop and what type? Try `ls -la /boot/efi` and see what is there. You do not need a separate book partition anymore. Doesn't mean you cannot configure your system that way just if you end up re-installing keep that in mind.

I deleted the older kernel version and updated successfully my system.The new installed kernel is not that big. It seams like the problem is solved even though I don't know why this happened. My main partition is encrypted. That's the reason why I use a boot partition and could not enlarge it.

There is a COMPRESS in /etc/initramfs-tools/initramfs.conf which is set to lz4 on my system -- check your system, if not set, that explains the larger initrd sizes.

The value is `zstd` on my system. I will watch the situation and when I have the same problem again I will change this value. Thanks.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
