How do I free up more space (increase partition size) in /boot on a VPS?

Question

My boot partition is full. I cannot apply system updates. How can I resize partitions? I don't want to remove old files, I only want to resize. I can not install gparted because I do not have desktop access. Is it possible to do it from webmin ?

I tried these methods:

My /boot partition hit 100% and now I can't upgrade. Can't remove old kernels to make room

How do I free up more space in /boot?

You might want to run 'apt-get -f install' to correct these:
The following packages have unmet dependencies:
 gparted : Depends: libatkmm-1.6-1 (>= 2.22.1) but it is not going to be installed
           Depends: libglibmm-2.4-1c2a (>= 2.36.2) but it is not going to be installed
           Depends: libgtk2.0-0 (>= 2.14.0) but it is not going to be installed
           Depends: libgtkmm-2.4-1c2a (>= 1:2.24.0) but it is not going to be installed
           Depends: libpangomm-1.4-1 (>= 2.27.1) but it is not going to be installed

 linux-image-extra-3.13.0-133-generic : Depends: linux-image-3.13.0-133-generic but it is not going to be installed
 linux-image-generic : Depends: linux-image-3.13.0-133-generic but it is not going to be installed
E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).

If I try apt-get -f install then I get "disk full" error.

I did delete old kernel files from webmin file manager, so I have more space on boot. I did not try resize process yet.

After deleting files from webmin file manager then apt-get autoremove worked. apt-get -f install worked. Everything is working good. Thanks everyone.
