Ubuntu 23.04 LTS, XFCE: docker-desktop fails to start

thomas-maeder commented 1 month ago

Description

Any attempt to start docker-deskop results in the following lines to be written: [14:13:14.009777147Z][main.statehandler ] sending to Dashboard: starting [14:13:14.009797868Z][main.virtiofs ] waiting for filesharing sockets to be created [14:13:14.009958375Z][main.virtiofs ] closing virtiofsd stdin pipe: close |1: file already closed [14:13:14.010276398Z][main.virtiofs ][W] virtiofsd error occurred while waiting for sockets: %!(EXTRA *errordef.dockerDesktopError=starting virtiofsd for /home: starting namespace for virtiofsd: fork/exec /bin/bash: permission denied) [14:13:14.010322691Z][main.engines ] stopping engine

Before that, the output looks ok.

Run /opt/docker-desktop/bin/com.docker.backend

Turns out, that the installation package and the docs are broken.

docker-desktop does some user namespace stuff
but the package fails to install a suitable apparmor profile
also the docs don't mention this with a syllable

thomas-maeder commented 1 month ago

Cf. #209 The fix provided there looks like extreme overkill, though, because it disable some aspect of apparmor for all applications.

Cf. #211 This workaround https://github.com/docker/desktop-linux/issues/211#issuecomment-2127698252 provides a more local fix that only affects docker-desktop; you want to replace "chrome" with something more suitable on the last line, though.
