This was a server issue, you can always report an issue in github and we’ll take a look, it took 10m to fix. But crucially it found an edge case that we hadn’t accounted for and haven’t run into so far, so we’ll work on making sure this won’t happen again: https://github.com/ublue-os/main/issues/643
The entire purpose is to conveniently access your files, so if that’s a problem use containers normally or pass a -h during distrobox create if you want to isolate home directories.
