Add pop to AUTH_TYPES in password.py

[Gary Perkins]

While troubleshooting my HP scanner, I was getting the error message "Error during device I/O (code=9)". When I ran the plugin download and install utility, I got the message "warning: pop distro is not found in AUTH_TYPES".

AUTH_TYPES is located in /usr/share/hplip/base/password.py, and defines if a distribution uses su or sudo for root privileges. It is used in __readAuthType(self), and if the distro is not defined, the default auth type is 'su'.

Pop! OS uses sudo authentication.

The fix is to add the line 'pop': 'sudo' to AUTH_TYPES.

I created a fresh Pop! OS installation in a virtual machine and verified that without the fix, hp-plugin tries to use su to authenticate as the root user (which for most users has no password), and the installation fails. Applying the fix, hp-plugin properly uses sudo and the installation is successful.

Is there any follow-up? I have the same issue.
