Hi Eyal,

It might be too long. But maybe you could solve it by fixing
systemd-resolved or disabling it completely. systemd-resolved should
contact DNS as usual, all your aliases should work there unless
overriden in /etc/hosts.

If you do not want to systemd-resolved to interfere, disable it by:

$ (sudo) systemctl disable --now systemd-resolved
$ (sudo) rm /etc/resolv.conf
$ (sudo) ln -s /run/NetworkManager/resolv.conf /etc/resolv.conf

It would not provide split-DNS on VPN, but should always reach dns
module in /etc/nsswitch.conf in default configuration.

If you want to use it and fix it instead, resolvectl output would help
us guess what might be wrong with it.

Cheers,

Petr
