I was getting an error running hplip-3.23.5.run once it hit the `make` command. So I ran the install script with debug output with the following command: `hplip-3.23.5/install.py -l debug`. Here's what that gave me:

```
The line `/usr/bin/ld: cannot find -lavahi-core: No such file or directory` indicated a missing library, so I googled `lavahi-core` and got references to a package `libavahi-core-dev.` I ran `apt install libavahi-core-dev`, tried the install again, and it worked. Attached is the full log file.
