Hi again Vincent :-)
Please ignore the part about adding more attributes to the SystemCallFilter
list; I don't think it's a road we want to follow.
What would be more important for me to know, is whether things work if
you change the RUN line to just
RUN+="/usr/bin/snap auto-import
Thanks Vincent. I think I got some hints: I downloaded the package from

issue let me know!

Alberto,
here it is
# cat /tmp/set.log
ACTION=add
BASH=/bin/bash
BASHOPTS=checkwinsize:cmdhist:complete_fullquote:extquote:force_fignore:globasciiranges:hostcomplete:interactive_comments:progcomp:promptvars:sourcepath
BASH_ALIASES=()
BASH_ARGC=()
BASH_ARGV=()
BASH_CMDS=()
Mmm... I'm running out of ideas! Mayve it's something with the
environment?
Vincent, can you try changing the rule to
RUN+="/bin/bash -c 'set > /tmp/set.log'"
and attach set.log here?

Vincent, maybe the udev rules are running under a user lacking some

Can you please try changing the rule to

and then paste here the output of id.log? (hopefully I didn't mess up
the quoting in the command :-) )

Hi Vincent, if I understand it correctly, this command scans the
inserted media for snapd assertions and imports them.
It's still not clear to me what's happening: even if you are running on
a classic system, the "auto-import is disabled on classic" is just a
notification and not an error: the
Hi, Alberto,
from the output below, auto-import is disabled. what this function is
used for？

Hi Vincent, thanks for reporting this. There should be some message
printed by the "snap auto-import" command when it fails.

and paste here the output?
