After upgrade from 1.3-rolling-201912110242 to 1.3-rolling-202002080217 I am unable to log in in any way, either via ssh or at the console. The only message printed on the console is "configuration failed!". I had to reboot with init=/bin/bash to examine the config and logs.
The vyos user is missing from /etc/passwd. diff of config.boot with pre-migration shows added quotes around all values in all sections.
vyatta-commit.log contains:
[ system login user vyos authentication public-keys jernej@jernej type ssh-ed25519 ] Invalid value
