Re: F32, mDNS, and nsswitch.conf
I waited until the final release before upgrading. But it's good to know this is actually a bug and has already been found. Thanks.

Re: F32, mDNS, and nsswitch.conf
Well, my printer was autodiscovered and configured via mDNS, so with the mnds4_minimal entry missing, it was not able to resolve the name. I could've gone an manually added it by IP address or a static DNS name but I liked the simplicity of it working "automagically" and I never remember the exact syntax I need and whether to set it up an IPP or HTTP or LPR printer. I've had issues with the mdns4_minimal entry in the past when accessing work resources over VPN, presumably because we have a .local Active Directory domain at work and mDNS uses .local as well. IIRC I had to move the mdns entry further back in the list to make it work, but that was a few years ago and probably on ubuntu. I never had to mess with it in Fedora until now.

F32, mDNS, and nsswitch.conf
I've been using Fedora on my laptop for a few years now, and on a newly built desktop for since just last summer. I've never had an issue upgrading, but I only recently became aware of the recommended post- install steps. https://docs.fedoraproject.org/en-US/quick-docs/dnf-system-upgrade/ So this time, after upgrading to Fedora 32 I followed the guide. When I was looking through the results of rpmconf -a, I chose to install the newer config files as I hadn't made any local changes, except in sshd_config. After the upgrade, it turned out I could no longer print from my desktop. My printer was discovered via mDNS and configured automatically in the past, it was really nice actually. I tried on my laptop as well and had the same result. I basically ignored it for a few days, installing updates and seeing if it was fixed, but it never was. Monday I had a bunch of printing to do for my kid's "remote learning" school assignments so I figured I'd dig into it. It turns out mdns4_minimal had been removed from host resolution in nsswitch.conf. I restored the nsswitch.conf.bak on both machines and my printer is back in business. I'm not sure if this is a bug? Was it removed for a reason or should I report it? Maybe it has been gone for a while now, and I've just been bringing the config forward. I suspect whatever package adds mDNS functionality also adds the entry to the default config and then I resotred the default back so this is basically user error. ___ users mailing list -- users@lists.fedoraproject.org To unsubscribe send an email to users-le...@lists.fedoraproject.org Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/users@lists.fedoraproject.org
