I can’t update this package why?
Last time on puli I had to update manually.
Download the correct binary version of adguard home on their github.
Connect via ssh and replace the binary.
Reboot and done
It seems like the integration is not really operational and the auto-update feature is inefficient.
The openWRT repo is behind since the updates are more often now.
Two solutions one check that there is plenty of room because I have had this twice, go to the subfolder and delete the old backup.
Second backup your settings and revert to factory defaults, set up your internet settings start up AdGuard and it then will update, reinstall LuCI and restore your backup, or do what Guillaume suggested.
