Error when opening terminal

[FrankBezemer]

Hi Don,

FYI
After running the container I am unable to open a terminal, I get error "Failed to fdwalk: Operation not permitted". The error is describer here as well. mviereck/x11docker#346

The solution they suggest does work for me as well, by running.
docker run -it -p 6080:6080 -p 56780:56780 --security-opt seccomp=unconfined --name alpine-novnc alpine-xfce4

Then the error is resolved.

thanks i have not received that error yet but i'll look into it

[martadinata666]

can you attach your system or docker version? 🤔

[novaspirit]

docker version 20.10.20

[martadinata666]

docker version 20.10.20

yes, as expected, I assume this is due older installation of docker version. let's see OP reply about the docker version.

[FrankBezemer]

I am using OpenSUSE Tumbleweed, my docker version (latest available in the repo) is:
Docker version 20.10.17-ce, build a89b84221c85

[martadinata666]

I tried to replicate it, but i cant, as for note My suse installation is minimal from netinstall.. So something in your system preventing it. Assuming the tumbleweed package updated correctly, likely selinux. You can check disabling and enabling to test it out.

[FrankBezemer]

SUSE including OpenSUSE uses apparmor, not selinux by default (it can if you enable it). Selinux is disabled in my setup, I've checked the apparmor logs and can't see anything related to docker.
If it is just an issue with my setup then ignore it, I'll troubleshoot some more later.

Cheers

I see, looking forward what you find. 👍
