Hello, quite often, and quite randomly I run into this situation that whenever Guix tries to rebuild a profile, and sometimes while downloading from local Guix hosts sharing their store items, the process will crash with the following error:

Other times it goes through. Current checkout is ff14bc60e56fb0c6636da1da9a850b7b04abb367, which isn't the most current, I know. I've been observing this behavior since some time now, and haven't figured out what the reason is behind it yet. The error message looks similar to [1]. The way this error appears is, that I usually have one host that I upgrade first, and then share the checkout and the store between hosts to speed up the upgrading process locally. Unfortunately the updater will crash randomly whenever the host starts scanning other hosts that are found through mDNS. Sometimes this happens while fetching new packages into a profile. I've set up publishing: --8<---------------cut here---------------start------------->8--- (service guix-publish-service-type (guix-publish-configuration (host "0.0.0.0") (port 3000) (ttl #f) (advertise? #t))) --8<---------------cut here---------------end--------------->8--- and of course host discovery in guix-service-type too.
