Not sure what happened to it but my unifi controller docker got dorked up to the point where I can't even remove it.  Just says "Removal in progress," if I try and manually remove it from ssh

root@HomeNAS:~# docker rm d260bd1fd45d
Error response from daemon: container d260bd1fd45d1abf7603bbd2a50ff0505f23b5cfab

or this

 

root@HomeNAS:~# docker rmi d260bd1fd45d
Error: No such image: d260bd1fd45d

but it shows up in the list when I

 

docker ps -a

I'm kind of scratching my head on this one, I just repulled the image and renamed it unifi-1.  Any tips on for getting rid of the old one? The fact that it's just sitting there gets under my skin.

Removing a container from the command line isn't the normal way. Did you try removing it in the webUI?

 

Maybe docker image corruption?

 

Go to Tools - Diagnostics and attach the complete diagnostics zip file to your next post.

Sorry, I should have mentioned that it fails from the webui which is what lead me to try to manually remove it. From the logs, it looks like there are now two with the same issue the other being my booksonic docker which I only run intermittently.

You can delete and recreate your docker image, then reinstall all your dockers exactly as before using the Previous Apps feature on the Apps page.

 

 

Well this solved my issues. I was a little apprehensive about deleting the image as I wasn’t aware of the previous apps options.
