Hi,

I have the same problem. I tried to install fsl on two machines, with the same issue. One machine: Ubuntu 20.04 (focal). Second: Windows 10 with Ubuntu installed from Windows Store.

Error: "This command returned an error: home/$user/fsl/bin/mamba env update -n base -f /tmp/tmp0ceysaja/fsl-6.0.6.3_linux-64.yml"

I tried to run the script with python 2.7, 3.7 and 3.10 and with/without admin rights (sudo). I tried to update the system, also did not work.

If anyone have any idea, I would appreciate it. 

Kind regards,
P
