    2.5 Make sure there is a plesk.gpg in /etc/apt/keyrings. If missing, grab it from http://autoinstall.plesk.com/plesk.gpg

    Tried this solution but for me Imunify360's repos will not acknowledge my adjustments made via the above steps no matter what. I opened a ticket with Plesk Support and will update once we get to a solution in case others face a similar issue.

    I tried all that, still getting the same NO_PUBKEY BD11A6AA914BDF7E error on the SSH command line. There is a chmoded new plesk.gpg file in both /etc/apt/keyrings and /etc/apt/trusted.gpg.d .

    When I use the interface, it says that there are no new Plesk versions (stuck at 18.0.52) - I want to get to 18.0.53 update 1 as I _think_ my smaller servers are falling over and getting stuck while trying to update. (Server hangs - will not allow SSH). This is on 1 - 2GB lightsail servers. Hangs every 24 - 72 hours. I was able to update some of my servers to the latest plesk and they seem to be running better.

    Interesting. I copied the plesk.gpg file to  /etc/apt/trusted.gpg.d/plesk.gpg - then chmod it. Then in the UI visit the page https://myserver.whatever/admin/server/tools and pick Plesk -> updates and then the file /etc/apt/trusted.gpg.d/plesk.gpg is removed. Is that expected or normal? I'm more of a C/Go/JS/PHP coder than sysadmin.

    https://talk.plesk.com/threads/no_pubkey-bd11a6aa914bdf7e.368962/ seems relevant. There is a bit by 'Mow' where he points out that things are self sabotaging...
