So i havent upgraded my PopOS 21.04 in a while and i keep getting this error message when trying to upgrade

`dpkg: error processing archive /var/cache/apt/archives/libxpm4_1%3a3.5.12-1_amd64.deb (--unpack): trying to overwrite shared '/usr/share/doc/libxpm4/changelog.Debian.gz', which is different from other instances of package libxpm4:amd64 Errors were encountered while processing: /var/cache/apt/archives/libxpm4_1%3a3.5.12-1_amd64.deb` I have tried: `sudo mv /usr/share/doc/libxpm4/changelog.Debian.gz $HOME` Although this seems to be kinda working as it momentarily fixes my upgrade although I need to keep typing this with the new package it tells me to move to $HOME I also tried sudo apt-get --fix-broken install and reconfiguring dpkg but I still have the same issue.
