opemmediavault plugin error on "Check"

[clach04]

I've been experimenting with pre-release and stable builds of Open Media Vault for rock64 (see https://github.com/ayufan-rock64/linux-build/issues/426 but right now I can only get stable to boot).

Occasionally when hitting "Check" for plugins I get and error popup with:

Code:

Failed to execute command 'export PATH=/bin:/sbin:/usr/bin:/usr/sbin:/usr/local/bin:/usr/local/sbin; export LANG=C.UTF-8; apt-get update 2>&1' with exit code '100': Reading package lists...

I think it is failing due to missing sudo, running in ssh session as root works:

Code:

root@rock64:~# export PATH=/bin:/sbin:/usr/bin:/usr/sbin:/usr/local/bin:/usr/local/sbin; export LANG=C.UTF-8; apt-get update 2>&1
