Every time I try to upgrade it shows me this message

sudo apt-get upgrade

You might want to run 'apt --fix-broken install' to correct these.

    Did you run sudo apt --fix-broken install?

  • @ajgringo619 Have you? That command literally never works.

  • @Cerin - I've switched to an Arch-based distro since that post. When using Linux Mint, I did have to use that command a couple of times. Maybe sicvolo's answer will work for you.

In certain cases you might also want to force the overwrite

sudo dpkg --configure --force-overwrite -a

Alternatively:

sudo apt -o Dpkg::Options::="--force-overwrite" --fix-broken install

    I scoured all over the internet to find this solution. :)

  • Dpkg really helped!

  • it's frustrating that this issue breaks the whole sytem update system. sudo dpkg --configure --force-overwrite -a was the solution: just beware that the things it lists as broken may indeed break: Tolerable if getting the rest of the system updated is in fact more urgent (as it often is, otherwise you miss security-critical updates). Issue affects far more than just libreoffice.

sudo apt --fix-broken install

Is not valid command for apt v.1.6.12. What should help is:

sudo apt install --fix-broken

or 

sudo apt reinstall

  • Given that apt itself suggests apt --fix-broken install, I think it’s safe to assume that variant works. apt reinstall won’t work on its own, it needs to be told what package to reinstall.

  • @StephenKitt apt still suggests the same, but wouldn't execute and give the help menu every time I execute apt --fix-broken install, but as suggested in the answer, apt install --fix-broken works perfectly fine and fixes everything.

  • You can try deleting the lock files if present. sudo rm /var/lib/apt/lists/lock You may also need to delete the lock file in the cache directory sudo rm /var/cache/apt/archives/lock
