Would it be acceptable to show a debconf dialog/warning to the user? For example
```
playonlinux requires a 32-bit installation of wine
Please make sure multi-arch is enabled:
dpkg --add-architecture i386 && apt update
And install the wine:i386 package:
apt install wine:i386
```
I spent some time debugging this before finding the bug report.
To make matters worse the playonlinux message is very vague.
I think reminding users to manually install a dependency would help
many.
Thanks
