@arubislander said in unknown filesystem type 'overlay'.: @dafeihong you probably want to run those tools in a LXD container. Try searching for LXD on Ubuntu Touch in the forum. Thank you very much. It sounds like the container solution I need. I'll go check its support for these tools.

@arubislander I thought directly compiling ofono-binder would offer more VoLTE settings options, but it seems I need to change my approach. I'm flashing the system again now, hoping that this time it will resolve the issue of enabling VoLTE for unsupported SIM cards. Thank you.
