Hi,
the upgrade from 5 System to latest 6 using sudo omv-release-upgrade stopped with this message....
W: GPG error: http://hwraid.le-vert.net/debian buster Release: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 6005210E23B3D3B4
E: The repository 'http://hwraid.le-vert.net/debian buster Release' is not signed.
N: Updating from such a repository can't be done securely, and is therefore disabled by default.
N: See apt-secure(8) manpage for repository creation and user configuration details.
I have an LSI/Avago Controller running on that system and on some other OMVs 6 running without problems...
Any ideas?
Found the solution - strangely there was something wrong with the key i think - i did the following update and after that the upgrade process started normal....
wget -O - https://hwraid.le-vert.net/debian/hwraid.le-vert.net.gpg.key | sudo apt-key add -
echo " deb http://hwraid.le-vert.net/debian $DIST main " > /etc/apt/sources.list.d/raidtoolRepo.list
apt-get update
thanks!
