No Filemanager after Update to debian 9

[evo]

Hello!

after i updated my app-template to debian 9 (dom0 is on fedora24) for
some special apps i can not run ANY filemanager anymore!

i tried to install thunar, caja, nautilus, nemo... they are all now on
my template... but nothing can be run.

Can somebody understand it and help?

Thanks!

Open a terminal in the qube and try to run (e.g.) nautilus - what
happens?

strange... i've tried it already yesterday with caja, dolphin and so on,
it gave me "command not found"

now i have nautilus over terminal with 3 warnings: "no space left on device"

so the problem was the missing space.
as i cleaned it, nautilus runs also over GUI.

thank you!
