I saw poor download rates about 4 kB/sec and many timeout errors:
An error occurred processing a GET request to http://myserver:8624/debian/archive.ubuntu.com/pool/jammy/universe/amd64/terminator/terminator_2.1.1-1_amd64.deb: The operation has timed out:

Thanks Stefan

If you're getting an error downloading a .deb file, it wouldn't be related to the feed/connector indexes (i.e. those In/Release files).

When you request a .deb file, ProGet will first check if the file is stored (cached) locally. If so, then it will send them file. Otherwise, it will "forward" the request to the connector and stream the file to you while saving on disk, so that it's cached for next time.

A timeout typically is related to network or hardware errors. The first thing I would work on is reproducing and isolating where theh error is occuring. You can delete cached packages from the feed using the UI, and also download files that way.

I would just use curl to test downloads.

Let us know what you find!

• Installation Ubuntu from LiveCD
• Installation apt List from ProGet Apt Proxy
• Installation repository key from ProGet Apt Proxy
• apt update (more then 330 packages)
• apt full-upgrade

The download of packages in the empty ProGet APT Proxy by apt full-upgrade produced the error messages.

This morning I start again with a new installation and with a new upgrade.

If the error happened during a apt update of hundreds of packages, then it probably was a case of server overload. Make sure to set a lower concurrent rate, which you can do under Admin > HTTPS SEttings > edit. 100 is the recommendation, and will be the default in ProGet 2026.

Thanks,

The upgrade worked this morning.
I think the clue is at feed properties
Index File generation Update in background

Works for me
Thank you

Oh yeah, that'll make a HUGE difference for public repositories. OTherwise it'll probably not work at all :)

Anyway glad it's working now

Thanks,
Alana
