Just before I dive into describing my issue, I just want to put out that I am quite new with Linux, so keep that in mind if I have not pointed out the obvious.

I have run into some issues with my Ubuntu server. Initially, I found that it was rebooting in a continuous loop. After forcing a power shutdown, and then removing the power cable, reconnecting and performed another boot, I was able to successfully boot the server. After some digging around, I believe the culprit to my server issues is that my boot partition is full.

You might want to run 'apt-get -f install' to correct these:
The following packages have unmet dependencies:
 linux-image-extra-3.16.0-33-generic : Depends: linux-image-3.16.0-33-generic but it is not going to be installed
 linux-image-extra-3.16.0-44-generic : Depends: linux-image-3.16.0-44-generic but it is not going to be installed
 linux-image-extra-3.16.0-51-generic : Depends: linux-image-3.16.0-51-generic but it is not going to be installed
 linux-image-generic-lts-utopic : Depends: linux-image-3.16.0-51-generic but it is not going to be installed
E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).

I seem to get similar outputs when trying to remove kernels 34, 36, etc.

I've done a lot of Googling but haven't come up with a solution. There is the one report to try 'apt-get -f install' with no packages but unsure how to do that or if I should even try.

Any help or pointers on how to fix this would be most appreciated!

Thanks,

Torbuck

  • You can use this answer askubuntu.com/questions/263363/…, just be sure to use the exact kernel name, using * is a little dangerous, after you delete some of them and get some space on /boot , use apt-get to fix and get your system up-to-date – bistoco Oct 21 '15 at 23:11
  • you could just cd /boot/ do ls then sudo rm linux images. The idea for all these tools, dpkg, apt, aptitude, whatever, is that they make your life easier. Until they simply fail to work. It sounds like you can identify the kernels you want to remove. If that is the case, don’t be afraid to do it manually. sudo apt-get -f install is just a command that trys to fix apt-get when it has broken dependencies. – j0h Oct 22 '15 at 1:08

Use sudo dpkg -r <pkgname> to remove each of the older kernel packages, and then once you free up some space by doing that, sudo apt-get install -f.

  • so would I do sudo dpkg -r linux-image-3.16.0-33-generic and then the same for 34,36 37, 38 and 39? – torbuck Oct 22 '15 at 0:02
  • @torbuck, yep.. in fact, iirc, you can do sudo dpkg -r linux-image-3.16.0-{{33,34,35,36,37}}-generic and get them all at once. – psusi Oct 22 '15 at 0:10
  • I seem to be having dependency issues with removing these old kernal packages: dpkg: dependency problems prevent removal of linux-image-3.16.0-33-generic: linux-image-extra-3.16.0-33-generic depends on linux-image-3.16.0-33-generic. dpkg: error processing package linux-image-3.16.0-33-generic (--remove): dependency problems - not removing Errors were encountered while processing: linux-image-3.16.0-33-generic – torbuck Oct 22 '15 at 0:19
  • @torbuck, ahh, you will just have to remove those as well. – psusi Oct 22 '15 at 0:58

I ended up just moving initrd.img-3.16.0-33-generic (plus 34, 36, 37 & 38) to a temp folder and then was able to successfully perform a sudo apt-get install -f. Once that was complete, I performed a sudo apt-get autoremove which successfully freed up some space on my boot partition. All is good now!
