Running the hubmle branch using WSL2 gets error on build.

Hi,

When using the tutorial on Ubuntu20.04 WSL2 the build fails with error:

• The terminal process "/bin/bash '-c', './build.sh'" terminated with exit code: 1.
• Terminal will be reused by tasks, press any key to close it.

It looks like the memory problem in WLS. Any idea on how to fix this fast ?

Thanks

You might want to see if the container has write access to that folder by trying to write a test file to it.

I'd guess there's a write permission issue with docker and your volume mounts? Windows tends to have extra access control settings
