Solved [FAILED] Failed to start Unbound DNS Resolver.

[gobenizzle]

Hi all,

I am a bit desperate...
our cloudron Server stopped working out of nowhere.
We get the error: [FAILED] Failed to start Unbound DNS Resolver.
I tried to reinitialize the unbound root.key.
This worked in so far as I get the unbound service running again. However I get a new error message:
"error: could not fflush(/var/lib/unbound/root.key): No space left on device"

Can you please help?

the hint is that you ran out of space, delete some files, make some space available and then restart the system.

@gobenizzle see the unbound section of https://docs.cloudron.io/troubleshooting/#recovery-after-disk-full in case you hit the disk space issue.
