[Bug 1971955] Re: systemd-udevd call unshare process when attaching nvme volume
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 program still exits with a 0 exist status. Yet, in the logs you provided, it appears as if the exist status is 1. Could it be that the error is not coming from "snap auto-import", but rather from the "unshare" command? Can you please try to manually edit the file (after making a copy of it!) and change the RUN line into RUN+="/usr/bin/unshare -m /bin/echo hello" and see if you still get those errors in the log? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1971955 Title: systemd-udevd call unshare process when attaching nvme volume To manage notifications about this bug go to: https://bugs.launchpad.net/dellserver/+bug/1971955/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
