Update Urbit / Urbit Pier?

Anyone running Urbit on their Umbrel node? I’ve been running for awhile but can’t get Urbit to update. In trying to install new, or update existing urbit application, I’m to I need to update the base OS.

I figured maybe I could backup my pier, delete urbit from umbrel, and then copy my pier back to umbrel. This isn’t working because I get the ‘Permission denied’ message when trying to copy or access my urbit pier.

Anyone have any suggestions on getting urbit updated to the latest version?
