What's the best way to solve this.

Had a few times difficulties with the login before, but then it worked at the 2-3 startup.

omv-firstaid tried, but no improvement.

The login GUI comes after the cleanup.

But after entering the user and password I get the same message as I wrote above.

I think I know what it is now.

Got the system running on an 8 GB flash drive.

A few days ago, I installed Docker and then Emby.

I guess now the storage space is at its limit.

Here again a few lines from the log:

Now the question is, what's the best way to change it.

First thought: Uninstalling Docker + Emby

Two thoughts: expand memory

Is there any other option?

Now I've stopped dockers and then performed omv-firstaid.

A login via the browser was then possible again as usual.

Now I have deleted Emby and will try the project on a Odroid C2.
