Hello, Looking at DpkgTerminalLog.txt, I believe the failure here was when the firefox deb helper tried to install the firefox snap, and failed when trying to connect to the snap store. Unfortunately there may not be much we can do here except suggest trying with a different network connectivity setup that might help the connection to the snap store succeed.
