Thanks for the projects, like your documentation and how you make it flexible.

I'm using the Configuration module to store the settings. That happens to be another module I wrote, so unfortunately I can't just leave it at that and blame the other module 😉

Bottom line, it looks like I may have misunderstood the free desktop XDG Base Directory specification. Bottom line: it's defaulting to XDG_CONFIG_DIRS (i.e. in PowerShell: $Env:XDG_CONFIG_DIRS) which seems to be set, on your system, to /etc/xdg/xdg-cinnamon -- I chose to make that the default because in my head, it corresponded to Windows "Enterprise Roaming Profile" -- however, looking at the free desktop spec just now, I think I may have gotten that wrong, and that location is more like the Windows "ProgramData" settings -- and worse, it may require root to write to it.

In any case, I should probably just change to using the user-specific location as the default export location (i.e. on Windows, LocalAppData, and on Linux, XDG_CONFIG_HOME).

If anyone knows anything about XDG, I'd love to get this right ...

For you, the quick fix is to reconfigure the Configuration module storage paths to point to paths where you have write access.

Open your local copy of the Configuration.psd1 file, and look around line 50 for the PrivateData PathOverrides, and set the EnterpriseData one (at least) to a location that you can write to -- probably the value of $Env:XDG_CONFIG_HOME but it doesn't really matter.

Just encountered this - running for the first time on a Ubuntu GUI.

I can confirm that none of the default XDG_... env variable are pointing to a user writable location.

EnterpriseData = "~/.local/share/" Did the trick for me.

So a bit more about this.
Per the specification, these environment variables, they have default values if they don't exist (fun!)

I think the biggest hurdle here, is that while you are looking for those paths, they don't exist by default. And I'm guessing your code attempts to create the empty directory.

After all, why would saving a local configuration try writing to Enterprise data ?

On a different note, a question:

Any way to manipulate the configuration in Configuration.psd1 programmatically?
I mean PowerShell's object based way and not a string search-replace?
