Bug#1099058: plasma-firewall: Installing plasma-firewall on a new system breaks mDNS

[Jeremy Lainé <jeremy.laine@m4x.org>]

Package: plasma-firewall
Version: 6.3.0-1
Severity: normal
X-Debbugs-Cc: jeremy.laine@m4x.org

Dear Maintainer,

I have just spent a considerable amount of time trying to figure out why
I was unable to find any network printers on a freshly installed laptop.
The laptop was installed using a nightly Debian Trixie installer.

It turns out that installing plasma-desktop pulled in plasma-firewall
which in turn pulled in firewalld. The default configuration for
firewalld seems to block mDNS, which completely breaks service
discovery. I have no doubt this can be configured but it seems odd to
have to make users jump through hoops to install their printer.

I can see two paths forward here:

- Downgrade the "Recommends" on firewalld | ufw to "Suggests".
- Change the default configuration of firewalld, in which case feel free
  to re-assign to that package.

Thanks in advance!

Jeremy
