What I did:
I shut down my Raspi on location A and switched off an USB HD
then I went to a complete other location B
here I unmounted the USB HD in Webmin and tried to mount another USB HD again in Webmin.
This did not work so I tried to do that with DIETPI-DRIVEMANAGER.. and that did not work, too.
that was the advise from DIETPI-Software.. but I could solve this mounting problem by my own.. Funny, but after a reboot drive manager worked again. I am used to see this behavior in Linux..
But next I run in another problem on installing ** home assistant.**
The installer refers to a file in /tmp, which I enclose to this case python-build.20250330230346.8247.log (995 Bytes)
