[3dprinter-general] Bug#1055468: Bug#1055468: python3-charon: Warning during boot about "Unknown username "ultimaker" in message bus configuration file"

[Gregor Riepl]

Hi Dave,

> During boot, I get a warning about a missing username "ultimaker". As far as I can tell this stems from the dbus configuration file packaged with python3-charon (/usr/share/dbus-1/system.d/nl.ultimaker.charon.conf) (I don't think it's the systemd configuration file that mentions the same user (/lib/systemd/system/charon.service), as I'm running Devuan with OpenRC).

Actually, this should no longer be an issue and is fixed in 
python3-charon 5.0.0-4. But we didn't backport it, so it still affects 
Cura in bookworm.

We have confirmation from Ultimaker that the daemon/dbus/systemd stuff 
in libCharon is only used on Ultimaker devices and shouldn't even be 
installed with Cura: https://github.com/Ultimaker/libCharon/issues/45

@myon, could we release a backported fix to bookworm, or should we leave 
it as it is? I don't have much experience with stable packaging policies.

Regards,
Greg
