I have been using ubuntu for 3 months now and I have come across this problem. An error message showed up saying

packages with unmet dependencies,update

When i tried to update it says

not enough disk space in /Boot.

I looked up some other answers in this forum and ran the command lines posted there but could'nt solve my problem.

Im pasting my terminal output below.

Ran the apt-get -f install command and got this output.

  • Could you please post text files, dialogue messages, and program output listings as text, not as images? To achieve the latter two you can either 1) select, copy & paste the dialogue text or terminal content or 2) save the program output to a file and use that. Longer listings (the editor will tell you what's too long) should be uploaded to a pastie service and linked to in the question. Thanks. – David Foerster Jul 08 '17 at 06:56
  • Did you try to run the command suggested in the output of apt-get, i. e. sudo apt-get install -f? Could you please [edit] your question to include its output? Thanks. – David Foerster Jul 08 '17 at 06:57

This is probably caused by having too many old kernels installed.

If you're happy with your current kernel and want to remove all the older ones, you can use this command to remove all kernels except the currently used one:

sudo dpkg --list | grep linux-image | awk '{ print $2 }' | sort -V | sed -n '/'uname -r'/q;p' | xargs sudo apt-get -y purge

I got this from this answer: https://askubuntu.com/a/254585/19779. I just ran it on my own computer to be sure it works as intended. It freed up 650MB. :)

not enough disk space in /Boot.

Can you mention whether or not you're using a separate disk partition for /boot? In case you did custom installation and created a separate boot partition, you might not have allocated enough space for it. I personally allocate a good 1GB for the /boot partition.
