Description of sign's "K" warning when performing apt command

  • 772

Every time I perform an apt command (fi sudo apt install <package-name> I receive the following warning messages regarding snap:

sudo apt-get install supertux
Pakketlijsten worden ingelezen... Klaar
Boom van vereisten wordt opgebouwd       
De statusinformatie wordt gelezen... Klaar
De volgende extra pakketten zullen geïnstalleerd worden:

2018/11/06 11:15:08.534162 main.go:150: description of install's "dangerous" is lowercase: "installeer het opgegeven snapbestand zelfs indien er geen vooraf erkende handtekeningen voor zijn, hetgeen betekent dat het niet werd geverifieerd en dus gevaarlijk zou kunnen zijn (--devmode impliceert dit)"
De volgende NIEUWE pakketten zullen geïnstalleerd worden:

My own translation of the error lines regarding snap:

2018/11/06 10:21:08.236205 main.go:150: description of sign's "k" is lowercase: "name of the key in use, use the default key"
2018/11/06 10:21:08.236582 main.go:150: description of install's "dangerous" is lowercase: "Install the snap even if there are no recognized keys which means that these were not verified and could be potentially dangerous (--devmode implies this")

I remember installing some snaps with this --devmode switch but cannot tell which. How can I search for them and uninstall?

apt snap

    I found the same issue reported on the snapcraft forum around two weeks ago here.

    Seems to be a combination of incorrect translations in snap, causing it to print these warnings, and an incorrect script in apt that should hide these internal warnings...

    A forum moderator called "chipaca" advised to change that internal apt script so that it correctly hides warnings from snap in that place, as intended. Quoting their reply:

    Ok, so the bug is in the file /etc/apt/apt.conf.d/20snapd.conf. It isn’t redirecting standard error as it should. It looks like this:

    AptCli::Hooks::Install { "[ ! -f /usr/bin/snap ] || /usr/bin/snap advise-snap || true"; };

    and you want it to look like this:

    AptCli::Hooks::Install { "[ ! -f /usr/bin/snap ] || /usr/bin/snap advise-snap --from-apt 2>/dev/null || true"; };

    the best way would be to just edit that file and add the needed redirection. If that seems too arcane, you could also run

    sudo perl -pi~ -we 's|from-apt|from-apt 2>/dev/null|' /etc/apt/apt.conf.d/20snapd.conf

    which should do the edit for you (and leave a backup of the old file in /etc/apt/apt.conf.d/20snapd.conf~ just in case). But you probably shouldn’t be running arbitrary commands from some rando on an internet forum. I hear it’s bad for your teeth.
