CUPS dependency issues in Crostini

So I recently acquired a new HP Chromebook and when I learned of its ability to run Linux apps in the Crostini container, I was more than pleased. My biggest issue right now is I can't get CUPS up and running so I can print from the installed Linux apps (LibreOffice, Thunderbird, Firefox). As far as I can tell, I have successfully installed CUPS itself but when I get to the next command, sudo apt install system-config-printer, the process breaks down with dependency issues and I get the following message and I can go no further:

Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:

The following packages have unmet dependencies:
system-config-printer : Depends: python3-cups (>= 1.9.60) but it is not going to be installed
Depends: python3-cupshelpers (= 1.5.11-4) but it is not going to be installed
Depends: system-config-printer-common (= 1.5.11-4) but it is not going to be installed
Recommends: system-config-printer-udev but it is not going to be installed
E: Unable to correct problems, you have held broken packages.

Anybody have any clue how to debug this? Thanks in advance!
