APT periodically receiving response code 444 during updates #113

Closed kusalk closed 2 years ago

kusalk commented 4 years ago

This error occurs even when PX has no proxy configured. So I suspect the issue is not related to communication with the proxy but the way PX passes thru connections.

APT output:

E: Failed to fetch http://archive.ubuntu.com/ubuntu/pool/main/u/ubuntu-meta/ubuntu-wsl_1.450.2_amd64.deb  444   [IP: 127.0.0.1 3128]

Error can generally be reproduced with the following (there must be pending OS updates). Note that repeated runs of the command may not throw an error (not reliably reproducible).

sudo apt upgrade

Also note that APT has its own proxy configuration and does not respect env variables.

Have the same problem described here: https://github.com/genotrance/px/issues/100

I've made some minor tweaks and no longer see any 444s with apt. Any testing with the latest versions will be appreciated.
