Cannot export PS1 over SSH

Trying to customize shell prompt on a Ubuntu 18 LTS server over SSH.

On the server, the .profile sources .bashrc correctly, and .bashrc has force_color_prompt=yes uncommented. The prompt is not colored.

Tried setting it manually. It does not export:

user@ubuntu ~ $ export PS1="[ ${debian_chroot:+($debian_chroot)}u is awesome: w ]\$ "

user@ubuntu ~ $ echo $PS1

u@h w $

But as root it works fine:

user@ubuntu ~ $ sudo su

root@ubuntu:/home/user# export PS1="[ ${debian_chroot:+($debian_chroot)}u is awesome: w ]\$ "

[ root is awesome: /home/user ]#

What is going on?

Perhaps your ordinary user's login shell is not bash?

Please edit your question and show us the output of echo $PROMPT_COMMAND. Ideally, show us the entire contents of your ~/.bashrc. Also show us the output of ps -p $$ as your regular user. @steeldriver are there any shells that accept the foo=bar syntax for variables and don't support PS1? It's defined by POSIX for sh so I would be very surprised to find an sh-like shell that doesn't understand it.

Checked $PROMPT_COMMAND as advised by @terdon:

user@ubuntu ~ $ echo $PROMPT_COMMAND

__git_ps1 "u@h w" "$(__drush_ps1 "[%s]") \$ "

Then looked harder at .bashrc and found:

# Include Drush prompt customizations.

if [ -f "/home/user/.drush/drush.prompt.sh" ] ; then

    source /home/user/.drush/drush.prompt.sh

fi

Drush was setting its own $PROMPT_COMMAND, apparently instead of PS1. Not sure how PS1 gets overwritten by this, but it does. Commenting out Drush's superfluous customization makes the problem go away. Thanks to @terdon.
