Discovered today that GrapheneOS (and its native apps) will not update when a VPN is in place on the phone. Aurora Store and F-Droid will update, but Graphene system updates and default app store don't work over the VPN.
Had been wondering why I hadn't received updates in recent weeks to the core OS, but most apps were updating successfully. Disabled the VPN temporarily and GrapheneOS updated itself, then re-enabled the VPN.
The past few Ubuntu release announcements have made it seem like the developers are not enthusiastic about their distributions and are in a holding pattern. The community spins in particular mostly read like "We had to put up an announcement, the kernel has been updated." There doesn't seem to be much innovation happening.
(The exception seems to be Ubuntu Studio. They still convey excitement and a sense of adding something new to the ecosystem.)
