Seems like plymouth got serious issues with argument parsing in 'ask-for-password' command
You can reproduce like following (possibly start one machine and ssh to it from another to see what is going on)
1. Start plymouth on tty8
# plymouthd --mode=boot --attach-to-session --pid-file=/run/plymouth/pid --tty=/dev/tty8; chvt 8; plymouth --show-splash;
2. Try first without --number-of-tries
$ plymouth ask-for-password --command='/bin/cat' --prompt="This is a password prompt"
works great
3. Now with --number-of-tries
# plymouth ask-for-password --command='/bin/cat' --number-of-tries=3 --prompt="This is a password prompt"
plymouth: ./ply-boot-client.c:272: ply_boot_client_process_incoming_replies: Assertion `request_node != NULL' failed.
Aborted (core dumped)
That's not only this.
4. if you add random incorrect argument it will open dialog but wont't display prompt
# plymouth ask-for-password --XXXX --command='/bin/cat' --prompt="This is a password prompt"
5. But if we add this to the very end the program will crash
# plymouth ask-for-password --command='/bin/cat' --prompt="This is a password prompt" --XXXX
plymouth: ./ply-boot-client.c:272: ply_boot_client_process_incoming_replies: Assertion `request_node != NULL' failed.
