I'm a tech newbie user who's just started using Horus and I'm loving it so far, but I had a warning pop up saying that I'm running out of disc space on /boot. Since I know enough to enter commands in the terminal but not to tinker with an OS, I tried this solution (Low Disk Space on boot warning) but it didn't work. I got this result: 0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded.

I've looked into other entries in this forum but balk at things that are over my head, like these:

Low disk space on file system elementary OS disk space getting low

Any ideas what to do?

Update: I tried Bleachbit to free up space but still got an error message saying I have even less space on my /boot folder now, so I tried Bleachbit again. It hung up on me, though, so I aborted the operation (it was able to free up over 30 GB of space, though) and just in case it worked I tried this solution again (Low Disk Space on boot warning) and this time got this:

sudo apt-get autoremove

Help, please?

  • Can you provide your disk partitions sizes? Also, can you use ncdu to find out what is taking that much space? Commented Mar 21 at 2:44

Did you ever get any help with this issue? I'm in the very same boat as you and can't find any topic that has helped. Did you? Could you pass it along?
