Description
Discovered my Docker host VM paused this morning. Interrogating the journal showed Exit=2 for docker.socket.
Rebooted the VM, ran Debian updates, rebooted again.
I've scoured all .env and docker-compose.yml files and confirmed there are no values with a space appended to them.
I don't know how to get dockerd to tell me where it's getting that from. Search engines have turned up nothing useful aside from suggesting there is an issue with a .env or docker-compose.yml somewhere.
Tried starting docker manually with sudo dockerd (full output is in the more info section) but get a panic error indicating there is a space appended to the hosts local IP address:

I've reached the limit of what I know off the top of my head and Google searches are telling me to wipe out all my containers and volumes. If that's really the only way to sort this out, I'd be satisfied hearing it from an expert and not a language model shoe-horned into my search results.
Reproduce
sudo dockerd
Expected behavior
docker should start up normally and resume containers.

Description
Discovered my Docker host VM paused this morning. Interrogating the journal showed Exit=2 for docker.socket.
Rebooted the VM, ran Debian updates, rebooted again.
I've scoured all
.envanddocker-compose.ymlfiles and confirmed there are no values with a space appended to them.I don't know how to get dockerd to tell me where it's getting that from. Search engines have turned up nothing useful aside from suggesting there is an issue with a
.envordocker-compose.ymlsomewhere.Tried starting docker manually with
sudo dockerd(full output is in the more info section) but get a panic error indicating there is a space appended to the hosts local IP address:I've reached the limit of what I know off the top of my head and Google searches are telling me to wipe out all my containers and volumes. If that's really the only way to sort this out, I'd be satisfied hearing it from an expert and not a language model shoe-horned into my search results.
Reproduce
sudo dockerdExpected behavior
docker should start up normally and resume containers.
