Description Martin Kyral 2019-02-19 07:37:10 UTC

Description of problem:

yum can't install modularized content into user specified install root because of missing /etc/os-release in the install root. IMO, the file shall be read from the standard location, if not found in the destination.

# yum --installroot=/var/tmp/tmp.FPC0jWdbj7 --nogpg install postgresql-server -y
Unable to detect release version (use '--releasever' to specify release version)

Comment 1 Martin Kyral 2019-02-19 10:12:22 UTC

I was instructed that there is --setopt=module_platform_id=platform:el8 option allowing instalation of modularized content into install root. Tried, tested - it works. It is documented but the mention is hidden in the huge man page. So hint in case of this failure (similar to --allowerasing / --skip-broken hints in case of package transaction problem) could help a great deal and would be enough as a fix for this bug.

Comment 2 Jaroslav Mracek 2019-03-12 18:16:42 UTC

I created a patch (https://github.com/rpm-software-management/dnf/pull/1355) that provides a hint how to set up the platform module.

Comment 3 Jaroslav Mracek 2019-06-10 10:06:17 UTC

I believe that the issue is solved by changed detection of module_platform_id. Now it is taken from available package that provides a system-release.

Hi Jarda,
could you please provide more details on how this is supposed to work? Thank you.

Found the answer here https://github.com/rpm-software-management/libdnf/pull/712
However bug 1698942 is not fixed and thus the detection capabilities are limited.
