For everyone who is not following the e-mail lists:
With the upcoming zypper version 1.14.90 and libzypp 17.37.1 (so I guess with the next Tumbleweed snapshot) parallel downloads will become the default for zypper. Therefore the usage of environment variables for that purpose will apparently not be necessary anymore.
Also I would like to quote the following from Benjamin Zeller’s message:
Recommended configuration (For Best Performance & Reliability):
While the automatic mode is a great improvement, we strongly recommend
manually configuring your repositories for the most robust experience.
Please take a moment to perform the following two steps on your
repository files (located in /etc/zypp/repos.d/):
Replace baseUrl= with mirrorlist=. This tells Zypper to fetch a list
of available mirrors. You can form the mirrorlist URL by simply
appending /?mirrorlist to the baseUrl.
IMPORTANT: Make sure there is a trailing slash (/) before the
?mirrorlist part.
Example: https://download.opensuse.org/tumbleweed/repo/oss/ becomes
https://download.opensuse.org/tumbleweed/repo/oss/?mirrorlist
Note: If you used a metalink entry like we suggested in the previous
mail, this is still supported as well.Explicitly specify the GPG key URL with gpgkey=. This enhances
security by ensuring the repository’s signing key is always fetched
directly from the official server.
For further details just read the mailing list link.
I am really looking forward to it.
