Curl command errors out

[Ithrial]

Hello

Trying to install this on Ubuntu 24.04.1 LTS outside of Docker to provide persistent storage to Portainer. When I run the Curl command provided, the command errors out with "dirname: missing operand"

I also have this error on an uptodate Arch install. Notably though, when I make curl save the script to a file instead and run that I don't get the error, but it also doesn't work. It just prints the parent directory to wherever I'm running it and seemingly does nothing

For instance if I'm in ~/Workspace/Docker/ and run ./local-persist-installer.sh then it'll print
/home/username/Workspace

edit : after some more searching it seems like this is a dupe of another issue (possibly several, it's not clear how actively maintained this repo is) and in #104 a 'solution' is given. Basically do what I suggested and save the install file, but then replace line 21 with the diff given in that issue's comments and it should work fine
