Thank you! was able to get it to run with 1-2 tiny modifications

Who has any issues with the above try the following:

@RainyZombie I got Ubuntu. Ubuntu_22_04.tar.gz: Permission denied with your Dockerfile, any solution?

Edit: I think its permissions issue, user steam, how to fix it?

[RainyZombie]

@fund440 Ubuntu_22_04.tar.gz should be downloaded in /home/steam/.fex-emu/RootFS/ where user steam should have permission, are you sure you used the dockerfile I posted and there are no previous errors before the permission denied one about the ubuntu archive?

I fixed it by running doing this

RUN mkdir -p /home/steam/.fex-emu/RootFS/
RUN chown -R steam:steam /home/steam/.fex-emu
RUN chmod -R 755 /home/steam/.fex-emu

USER steam

WORKDIR /home/steam/.fex-emu/RootFS/

I did this too to /home/steam/Steam

idk why I copied your exact Dockerfile 😅

You can put on
'ENTRYPOINT FEXBash'
then just attach on container.
