Symbolic Link Failure

Picked up a new Pi (400) and trying to install Channels. It gives:

curl -f -s https://getchannels.com/dvr/setup.sh | sh
Downloading Channels DVR 2021.01.15.1649 (linux-armv7l) to /home/pi/Media/channels-dvr......
ln: failed to create symbolic link 'channels-dvr/latest': Operation not supported

ERROR: Installation of Channels DVR failed.
ERROR: Please contact [email protected] with the full output above.

I've tried both creating the channels-dvr folder myself and letting the script do it. Error is the same. The output of "ls -alh /home/pi/Media/channels-dvr" is:

The file system you're using doesn't support symbolic links.
