Topgrade or it's child processes successfully connect to a remote address.
What actually happened?
I have spurious errors that a topgrade child process fails to connect.
This sometimes happens with
SSH:
Connecting to HOST...
ssh: connect to host HOST port 22: Network is unreachable
– even if I'm currently connected to HOST and actively transferring some data to said host.
Docker:
Error response from daemon: Get "https://ghcr.io/v2/": dial tcp: lookup ghcr.io on [::1]:53: read udp [::1]:36276->[::1]:53: read: connection refused
zypper (no specific error at hand, but also some kind of cannot find/connect to server)
(If I retry the step a second time, it usually works.)
Additional Details
At first I was pretty sure that this is an issue on my side, however it also happens on other systems (e.g. my server which is in a remote data center with high-reliablity network connection and tight network monitoring). So I started looking at the logs, but found nothing. Additionally, I setup some monitoring on my local machine, and again nothing.
The weird thing is: This only happens with topgrade. I literally have weeks where everything else works flawlessly without network errors etc, and then there is topgrade which reliably fails every two days.
And to be honest im quite a bit puzzled – I'm not sure if it's even reasonably possible for topgrade to introduce weird network errors for child processes; so I'm not sure if this is even related to topgrade – however, this is the only context where such errors occur 🤷🏻♀️
Which operating system or Linux distribution are you using?
This happens with macOS Monterey, macOS Ventura and openSUSE Tumbleweed
