Hi, Please consider to add "No such file or directory" as output for when passing a non-existing .deb to `apt install`. It would make it a not clearer to the user what is going wrong. $ apt install ../non-existing.deb Error: Unsupported file ../non-existing.deb given on commandline $ ls ../non-existing.deb ls: cannot access '../non-existing.deb': No such file or directory Best regards, Niels
