Losing my mind here. Trying to install Signal on Fedora as a stop-gap while I troubleshoot Whonix not working with Signal.
Trying to install Signal via flatpak, which requires flathub. Installing flathub I get this error:
[user@fedora-42-xfce ~]$ sudo flatpak remote-add --if-not-exists flathub https://flathub.org/repo/flathub.flatpakrepo
error: Can't load uri https://flathub.org/repo/flathub.flatpakrepo: While fetching https://flathub.org/repo/flathub.flatpakrepo: [6] Could not resolve hostname
Any and all help is much appreciated.
