Do you have "deb cdrom:" lines in your sources.list ? If so, comment them out and try whether these complaints vanish. > E: The repository 'file:/media/deploy/UUI buster Release' is not signed. > N: Updating from such a repository can't be done securely, and is therefore > disabled by default. > N: See apt-secure(8) manpage for repository creation and user configuration > details. I understand that apt-secure can be used to create a signed repo. I assume that you'd have to copy the ./dist and ./pool trees to a writable filesystem before producing the signature. But the internet proposes as quick workaround in sources.list: deb [trusted=yes] file:/media/deploy/UUI buster main (documented in man sources.list) ------------------------------------------------------------------------- Aren't any sources.list experts present who could keep me from guessing around ? Have a nice day :) Thomas
