I am trying to update my system (Ununtu 14.04) but Ubuntu tells me that I have not enough space on file system root (although it is 20GB). I searched for it and tried many suggestion including autoremove, autoclea, etc. For all of above system brings an error - unmet dependencies. Another search and -f install, dist-upgrade, purge remove unattended-upgrades, remove generic... and many more, all are unsuccessful.
I am either unable to update, install or uninstall because of low root space or unmet dependencies. Typical error message looks like this...
Reading package lists... Done Building dependency tree
Reading state information... Done You might want to run 'apt-get -f install' to correct these: The following packages have unmet dependencies. linux-headers-generic : Depends: linux-headers-3.13.0-139-generic but it is not going to be installed linux-image-generic : Depends: linux-image-extra-3.13.0-139-generic but it is not going to be installed linux-signed-image-3.13.0-139-generic : Depends: linux-image-extra-3.13.0-139-generic (= 3.13.0-139.188) but it is not going to be installed E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).
The following packages have unmet dependencies. linux-signed-generic : Depends: linux-headers-generic (= 126.96.36.199.148) but it is not installable linux-signed-image-3.13.0-139-generic : Depends: linux-image-extra-3.13.0-139-generic (= 3.13.0-139.188) but it is not installable E: Unmet dependencies. Try using -f.
Hours of searching brought me here, sorry and please help.
