Bug ID: 410192
Summary: At logout warn if no valid shell installed; At login
show adequate error
Product: plasmashell
Version: 5.16.3
Platform: Other
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: general
Assignee: [email protected]
Reporter: [email protected]
CC: [email protected]
Target Milestone: 1.0
SUMMARY
If a user logs out in case there's no valid shell set for the user in
/etc/passwd, it won't be possible to login for the user again, but instead it
SDDM says "invalid password".
BACKGROUND STORY
With pacman I installed zsh besides bash and sh. I then suspended the system to
disk. After wake up, I was logged in again automatically, though all before
opened terminals/shells had been closed and zsh had been set as default. After
checking all configuration which came to my mind to revert to bash, I decided
to uninstall zsh via pacman.
Finally I rebooted the system. At the login prompt SDDM told me my password
were wrong.
Fortunately I could login as root with the very same password and change the
shell from "/bin/zsh" to "/bin/bash" in "/etc/passwd".
QUESTION
I am not sure if I have to report this to Manjaro or pacman or SDDM upstream
(instead)?
STEPS TO REPRODUCE
1. Change your user's shell in /etc/passwd to something invalid
2. Logout
3. Try to log in again
OBSERVED RESULT
At logout or restart there's no warning.
At login it says misleadingly "invalid password".
EXPECTED RESULT
At logout warn that's there's no valid shell for the user and a login
afterwards may become impossible.
At login tell the user that there's no valid shell defined in /etc/passwd
instead.
