Hi folks,
I’ve had this issue for a while, but haven’t had the time to triage it until now.
I’m able to update via the CLI, but I get errors when I try to do it from the GUI.
In the logs I’m getting lots of "Permission denied"s - output below.
I always just assumed that I did something wrong when I first span up this LXC in Proxmox - I didn’t originally install in the “pi” user and do had to some chowns to get it working.
However, I just created a new Ubuntu 22.04 LXC. Did my updates, created “pi” user and followed all the instructions on the docs.openenergymonitor scripts page. The install ran successfully, no errors. I was able to create a new user and login. However, when running my first software update via the GUI, I’m met with the same errors.
I compared the user and group for a bunch of these locations - see below.
/var/www/emoncms - drwxr-xr-x 8 root root 13 Mar 9 22:58 .git
/var/www/emoncms/Modules/app - drwxr-xr-x 8 root root 13 Mar 9 22:58 .git
etc
/opt/emoncms/modules/backup - drwxr-xr-x 8 root root 13 Mar 9 22:58 .git
I suspect most of this is root root as when I originally installed I did a “sudo ./main.sh” … when logged in as the “pi” user should this have been run with a sudo?
