One problem with Galaxy installation on Windows Subsystem Linux

Hi, everyone. I need your help.
My system is Windows Subsystem Linux (WSL). I would like to install a local galaxy for bioinformatics analysis. I am following the instruction as below:
$git clone -b release_21.01
$cd galaxy
When I use “sh”, I enountered an error as the attached picture show:

/mnt/f/galaxy/galaxy$ sh
: not found
: not found
: not found 10: cd: can’t cd to .
: not found 12: .: Can’t open ./scripts/


I don’t know what’s wrong with it. I have tried google, but still could not solve the problem. Could someone help me? thank you.
