Description Christoph Müllner 2016-11-16 13:09:57 UTC

Description of problem:

On my aarch64 machine (running Fedora 24 (upgraded from a Fedora 21 installation)) the installation of debuginfo
packages does not work, because the configured yum/dnf metalink provides wrong mirror URLs.

The metalink in use is:
http://mirrors.fedoraproject.org/metalink?repo=fedora-debug-24&arch=aarch64

It provides mirrors of the following style:
https://dl.fedoraproject.org/pub/fedora-secondary/development/24/Everything/aarch64/debug/tree/repodata/repomd.xml

Expected (working) style would be:
https://dl.fedoraproject.org/pub/fedora-secondary/releases/24/Everything/aarch64/debug/tree/repodata/repomd.xml

A workaround is to comment the metalink line in /etc/yum.repos.d/fedora.repo and use this baseurl line in the [fedora-debuginfo] section:
baseurl=https://dl.fedoraproject.org/pub/fedora-secondary/releases/24/Everything/aarch64/debug/tree

How reproducible: simply install glibc debuginfo

dnf -v debuginfo-install glibc
cachedir: /var/cache/dnf
Loaded plugins: protected_packages, generate_completion_cache, builddep, copr, Query, debuginfo-install, system-upgrade, noroot, needs-restarting, config-manager, download, playground, reposync

Thanks for the bug report. This is now fixed:

$ curl -s 'http://mirrors.fedoraproject.org/mirrorlist?repo=fedora-debug-24&arch=aarch64' 
# repo = fedora-debug-24 arch = aarch64 country = DE country = FR country = NL country = CZ

http://ftp.nluug.nl/os/Linux/distr/fedora-secondary/releases/24/Everything/aarch64/debug/tree/

and an upstream ticket is opened to get this fixed permanently:
