Once in recover mode, sudo snap install http 4. switch back to run mode: sudo http --pretty=format POST snapd:///v2/systems/$(ls /run/mnt/ubuntu-seed/systems/) action=do mode=run When I did this, the system never seems to fully return to run mode. I get errors about a soft lockup (see below) on the serial console after it reboots. However, if I pull the power at that point, and plug it back in, it does get back into run mode ## Info: input data size = 2 = 0x2 Hit any key to stop autoboot: 0 switch to partitions #0, OK mmc0 is current device Scanning mmc 0:1...
