dpkg: error processing archive /home/Me/Downloads/slack-desktop-2.1.2-amd64.deb (--unpack): trying to overwrite /usr/share/doc/slack/copyright', which is also in package slack 0.15.2-7
dpkg-deb: error: subprocess paste was killed by signal (Broken pipe)
Errors were encountered while processing: /home/Me/Downloads/slack-desktop-2.1.2-amd64.deb
