Low disk space boot volume is full

Post by Spiderspoon » Mon Apr 08, 2019 1:01 am

When doing updates yesterday, which included updating kernels, I got a message:
The volume "boot" has only 21.2 MB disk space remaining.
Can I delete old kernels, and how do I do this?

In Update Manager, View, Linux Kernels, it says:
You are currently using the following kernel: 4.15.0-47
Now I have Kernels 4.4, 4.8, 4.10, 4.11, 4.13 plus a whole lot of 4.15.0.
Kernels, 4.15.0-39 through to 47 are installed.

Which ones can I delete, and how do I do that?
Thanks
John

Update
I did some research elsewhere on this forum etc and found that individual kernels can be removed.
In my case only a few, about 6, were installed. The ones that were installed had Remove buttons. All the others were not installed and thus did not have Remove buttons. So I guess now that these ones are not taking up any space. I don't know why they are listed. They are available to be installed, but I have no need to do that.
So I removed a few of them and what remains are the current one, 4.15.0-47, which is marked as Active. 46 and 45 are installed. I have left them there.
I am now no longer getting the low disk space warning. So I guess that every time I update a kernel, I could remove an old one.
Any comments on this? Thanks.

Yes. For a way to automate this see here: viewtopic.php?p=1514402#p1514402

If you ever upgrade, in LM 19.2 old kernels will be cleaned out automatically.

I have just downloaded 19.1 Cinnamon.
I have done the Integrity Check, but I am getting stuck on the Authenticity Check.
Can you give me a link for help with this?
Thanks.

Because they are available to you, so that you have a choice. Specific hardware, that you may or may not have, might need it.

The system doesn't know or anticipate all your needs, so it's giving you options.

Yes, that is a very good habit. Keep the active one (of course) and one that you used before. All others can go.

If your issue is solved, kindly indicate that by editing the first post in the topic, and adding [SOLVED] to the title. Thanks!

The Linux Mint Installation Guide and "How to verify ISO images" both have details.

If you're having specific issues, you'd get the most help by posting a new topic specific to them. :)
