"/boot full" error, even after emptying. Encrypted hdd.

[CTolley]

Cannot install large "Ubuntu base" updates. Smaller updates work fine, but 80+M do not. I have cleaned all but the current kernel out of /boot, but the error persists. I have tried many steps, and am only submitting the bug report after no fix was discovered on this thread:

http://ubuntuforums.org/showthread.php?t=2235403

I checked the box for security vulnerability only because of the "Ubuntu base" updates being the problem. I have not had any security issues at this time.

Sometimes GUI environments don't delete files when you delete them, instead it moves them someplace else, making it far harder to find the files to remove.

I suggest looking through ls -la /boot/ output to look for potentially hidden files. If /boot isn't on its own filesystem you may need to look elsewhere for a way to free up some space. It might be best to head to IRC for help so you can get some interactive advice.

Thanks

Before this issue, I had 4 kernels and accompanying files. Now, it's only the one kernel and other required stuffs.

[CTolley (ctolley64)]

Also, boot is on it's own file system. I have roughly 250G free on the usable hdd. In future installs, I won't separate /boot, but it seemed logical at the time, and I haven't had an issue since I started using Ubuntu at 8.10. This is my first encrypted install, and other encrypted users are experiencing the exact same error.

Status changed to 'Confirmed' because the bug affects multiple users.
