While installing Pop!_OS, if a user enters a colon in the Full Name field, on the subsequent reboot the system is unstable, fails to load the login screen, and then users can't login.
Steps to reproduce (if you know):
In this instance, the breakage happened when setting the Full Name to: "Firstname: Lastname:" (with two colons). It's unclear if it breaks with a single colon, or if both are needed.
Expected behavior:
The installer should prevent using the colon character in that field (I believe it's breaking /etc/passwd)
Distribution (run
cat /etc/os-release):Pop!_OS 21.10
