Not enough free disk space on /boot

Not able to install updates for Ubuntu, or even remove older packages from /boot

Many answers suggested good solutions, but again I am not able to even remove older packages from /boot.

Not enough free disk space when upgrading

Unable to update ubuntu applications because there is not enough space on /boot

I am stuck in a loop here, my /boot size is 256M

df -h output:

"*I am not able to even remove older packages from /boot*" Correct: `rc` means that kernel has *already* been removed. That's merely of index of known packages, not a list what's actually on your system. Please edit your question to show the complete output of `ls -lah /boot`. Check that output for old, orphaned files that can be safely removed.

Your boot-partition is way too small.

I struggled with fixing the issue since I found that I did more damage than I expected, and reinstalled ubuntu leaving more space for swap and boot this time, I was not aware of this configuration when I first installed it. thanks for the answers. the question can be closed.

That's not how AskUbuntu works. You can flag you own question, if you wish. But it's better if you answer your own question to help future users with a similar problem.

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.
