Just had this occur to myself as well. Same symptoms as others have reported. Endless "Updating all Containers" loop.
* Just upgraded to 6.11.5 this morning, no issues with upgrade
* My docker install I have set to use directories, not a single docker img
* Wen to Docker, clicked [check for updates], 6 containers with updatse
* clicked [update all], update window/log appears
* Initially pulled data for updates to containers, successfully restarted them, then went into a loop starting at the first container again and attempting to pull an update, found no changes, but continued to restart container, then move onto the next one.
Diagnostics attached. Diagnostics were created from another tab while the system was still looping on trying to update the containers.
I also saw that there was a container that wasn't updated (unfortunately don't know if it was part of the 6 that had updates earlier as I didn't catch it fast enough). Clicked "apply update" next to that container specifically and it only updated that one container, then showed [done] button.
