Synching channels with updates.suse.com fails with "Curl error 92"

This document (000021096) is provided subject to the disclaimer at the end of this document.

Environment

SUSE Manager 4.2
SUSE Manager 4.3

Situation

SUSE Manager reposync logs are showing the following types of errors when synching channels:

Repository 'sle-manager-tools15-updates-x86_64-sp4' is invalid.
[sle-manager-tools15-updates-x86_64-sp4|https://updates.suse.com/SUSE/Updates/SLE-Manager-Tools/15/x86_64/update/<token>] Valid metadata not found at specified URL
History:
 - [|] Error trying to read from 'https://updates.suse.com/SUSE/Updates/SLE-Manager-Tools/15/x86_64/update/<token>'
 - Download (curl) error for 'https://updates.suse.com/SUSE/Updates/SLE-Manager-Tools/15/x86_64/update/content?<token>':
   Error code: Curl error 92
   Error message: HTTP/2 stream 1 was not closed cleanly: PROTOCOL_ERROR (err 1)

Resolution

SUSE has released updated libzypp packages for SUSE Manager 4.2 and 4.3. To resolve this issue, please update SUSE Manager 4.2 Servers to version 17.31.13-150200.66.1 of libzypp or higher, and SUSE Manager 4.3 Servers to version 17.31.13-150400.3.30.1 of libzypp or higher.

If you cannot install the updated libzypp immediately, there is a workaround, which is to add the following line in the [main] section of the file /etc/zypp/zypp.conf:

techpreview.ZYPP_MEDIANETWORK=1

Note: a reboot of the SUSE Manager Server is required to ensure that the change takes effect for both the resolution and the workaround.

Cause

The upstream delivery network was updated recently to a version that enforces a part of the HTTP/2 protocol that does not allow spaces at the end of fields. SUSE Manager had been adding a space on one field all along, and the upstream delivery network had been ignoring it. Now that it is being enforced, reposync will not work without the updated libzypp or the workaround.
