Haven't been able to update for a few weeks now. The update only has errors from Brave browser ..

Then the upgrade keeps giving me this error on a vlc dependency


sudo apt-get upgrade

You might want to run 'apt-get -f install' to correct these.
The following packages have unmet dependencies:
vlc : Depends: vlc-bin (= 2.2.8-2~xenial3) but it is not installed
E: Unmet dependencies. Try using -f.

So I try this ..


sudo apt-get -f install vlc-bin

Found a similar issue at https://askubuntu.com/questions/148383/how-to-resolve-dpkg-error-processing-var-cache-apt-archives-python-apport-2-0

So, did this ..


sudo dpkg -i --force-overwrite /var/cache/apt/archives/vlc-bin_2.2.8-2~xenial3_amd64.deb
sudo apt-get -f install vlc-bin
sudo apt-get update
sudo apt-get upgrade

and it all looks fine now. :)

That's a dirty solution. There is no vlc-bin in the official repositories for Ubuntu 16.04, so I don't know where you got it and I don't know where you got that vlc that depends on it.

Your problem with Brave browser seems unrelated.
