Incus arch-linux container - pacman update errors `Failed to write change to /sys/device...`

1

Hi,

I am using a archlinux incus container. It works fine, I’ve noticed when I try to update the packages using pacman, the packages install but I get a lot of Permission denied errors…maybe 100s of errors. They all seem to be trying to write to /sys/devices…

I have a feeling I am doing something wrong (or missing an option or something…)

I am issuing the command as follows (in the container)

container> sudo pacman -S -y; sudo pacman -S -u;

Here are a couple of errors in case it helps

device:72: Failed to write 'change' to '/sys/devices/LNXSYSTM:00/LNXSYBUS:00/PNP0A08:00/device:43/device:45/device:72/uevent': Permission denied
...
tty47: Failed to write 'change' to '/sys/devices/virtual/tty/tty47/uevent': Permission denied
...
scsi_tmf_8: Failed to write 'change' to
...

That looks normal to me (if a bit verbose).

Basically something in your package update seems to be running an udevadm trigger or equivalent. This attempts to write change to every uevent file in /sys.

Most of those devices are not owned by the container but owned by the host instead, so they won’t let you write to the file.

Sorry for the late reply…as I mentioned in the post, the install works fine, everything works fine…I was just worried by all the errors.

Thank you for your response…One reason for my late response is that I have not been able to pin down exactly what is writing to uevent. I think on my system it maybe Mkinitcpio.

I will come back to this problem later…I am hoping that I can avoid all the error messages at some point :slight_smile:
