Printers are not uninstalled when a user logs out

[garblixa]

In a Debian installation, printers are not uninstalled when a user logs out.
The reason is that, apparently, the PAM environment only has the environment variable PATH=/bin:/usr/bin when logging out, and therefore lpadmin cannot be found.

/usr/lib/python3/dist-packages/linuxmusterLinuxclient7/printers.py:

def _uninstallPrinter(name):
logging.info(f"Uninstall Printer {name}")
uninstallCommand = ["timeout", "10", "lpadmin", "-x", name]

FIX:
def _uninstallPrinter(name):
logging.info(f"Uninstall Printer {name}")
uninstallCommand = ["timeout", "10", "/usr/sbin/lpadmin", "-x", name]

Is lpadmin guaranteed to always be located at /usr/sbin/lpadmin on all platforms?

@dorianim
That's a good question. In the distributions I maintain, lpadmin is indeed located in /usr/sbin. It would probably be cleaner to either expand the PATH variable when the script is called, or check the standard paths to see where lpadmin is located.
