I keep getting emails from one instance of omv (odroid):
subject [blackboxrotava] Cron <root@blackboxrotava> if test -x /usr/sbin/apticron; then /usr/sbin/apticron --cron; else true; fi
text: W: http://apt.armbian.com/dists/bookworm/InRelease: Key is stored in legacy trusted.gpg keyring (/etc/apt/trusted.gpg), see the DEPRECATION section in apt-key(8) for details.
pls help what to do.
