I tried everything like removing the 24 kernel manually but no matter what I do this is my output of sudo apt-get upgrade:

Reading package lists... Done

Building dependency tree       

Reading state information... Done

Calculating upgrade... Done

The following packages will be REMOVED:

  linux-image-4.4.0-24-generic linux-image-extra-4.4.0-24-generic

0 upgraded, 0 newly installed, 2 to remove and 0 not upgraded.

**7 not fully installed or removed.**

After this operation, 217 MB disk space will be freed.

Do you want to continue? [Y/n] y
