[Nottingham] systemd-resolved Failed to send hostname reply: Invalid argument

[Phil Bass]

Hi, guys.

It was good to meet a few of you on jitsi last night.

A few days ago I installed Linux Mint 20 on an old Windows laptop. I haven’t fiddled with any settings (my sysadmin credentials are somewhat lacking but I can follow instructions 🙂). The machine connects to my WiFi but can’t access the Internet. The Logs app contains multiple error messages that say:

systemd-resolved Failed to send hostname reply: Invalid argument

Googling for this error message throws up a GitHub thread <https://github.com/systemd/systemd/issues/11626> dating from Feb 2019. The problem was originally associated with sleep/wakeup in Arch Linux but has also been reported as a permanent problem preventing access to the Internet and in Ubuntu. There’s no resolution in that thread and the last post was yesterday.

I’ve also found a thread on a Manjaro forum <https://forum.manjaro.org/t/i-broke-my-dns-configuration-limited-connection-to-internet-on-manjaro/122487/28> that suggests masking or disabling systemd-resolved and that has solved the problem for the original poster. Is that worth a try?
