I'm not currently using that board, but I can bring it back up if needed for testing/reproduction.
I wasn't using a prebuilt image, I was installing Ubuntu using debootstrap (IIRC, booted originally with the 18.04 based image provided [0], or "cross" installed originally from a Debian image). So totally unsupported, and for the specific case of the BeagleBone Black there were some issues with Ubuntu's u-boot (something about old configuration flags for the SPL?), but I do think making the change would be helpful as for other boards it does "just work". 0: https://elinux.org/BeagleBoardUbuntu#All_BeagleBone_Variants_and_PocketBeagle -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1917903 Title: Kernel flavors specified that aren't in Ubuntu To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/flash-kernel/+bug/1917903/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
