The issue here was that unbound was not working. Because of that, all the docker image updates are failing like so:

2022-12-06T03:38:02.801Z box:shell startGraphite exec: docker run --restart=always -d --name="graphite"         --hostname graphite         --net cloudron         --net-alias graphite         --log-driver syslog         --log-opt syslog-address=udp://127.0.0.1:2514         --log-opt syslog-format=rfc5424         --log-opt tag=graphite         -m 429916160         --memory-swap 536870912         --dns 172.18.0.1         --dns-search=.         -p 127.0.0.1:2003:2003         -v "/home/yellowtent/platformdata/graphite:/var/lib/graphite"         --label isCloudronManaged=true         --read-only -v /tmp -v /run "cloudron/graphite:3.2.0@sha256:182e5cae69fbddc703cb9f91be909452065c7ae159e9836cc88317c7a00f0e62"

It was hard to figure why unbound is not working, all queries fail with ESERVFAIL (VM, Hyper-V, router, many things here). It's some networking related issue hard to diagnose without getting a full hand on the setup. The workaround was to add a file called /etc/unbound/unbound.conf.d/forward-everything.conf with the following:

forward-zone:
    name: "."
    forward-addr: 1.1.1.1
    forward-addr: 8.8.8.8

Then, systemctl restart unbound . After that, host cloudron.io 127.0.0.1 should work.

Finally, systemctl restart box will then bring up all the containers again.
