I started to upgrade to beta7 and /admin/upgrade/docker_manager worked fine, but after that I hit Upgrade All and it stayed stuck here:

But /admin/upgrade is still stuck in “Upgrading…” (same when I click through to “Upgrade all”)
I’ve checked on mobile and I get the same, so it’s probably not a caching issue.
