With latest client rc build : .../pub/rhel/rel-eng/latest-RHEL-7/compose/Client/x86_64/os/

On virtual machine and with ja_JP language for the anaconda installation.

Thanks,
Robert

I think we are assuming that the languages in which you have installed desktop are the base languages and we don't need to store information about it in /var/lib/yum/plugins/langpacks/installed_langpacks file. We even will not need to remove those langpacks is the assumption yum-langpacks is following.

Based on above information, all things reported in bug description are expected.

So apparently installed_langpacks is not populated by anaconda.
This seems slightly inconistent.

(Naively I would have expected langlist to list the langs that have langpacks installed, or default lang used by yum-langpacks.)

Lijun: if this is not a regression, I think we can move this to 7.2.

I think yes we can move it to 7.2.

Fix to add informative message when installed_langpacks file not available

I am still not convinced for adding base languages in installed_langpacks but maybe I will visit this again sometime later when we start next development cycle.

For now proposing langlist command fix that will make sure installed_langpacks file exist on the system else print "No langpacks installed".

Set PM Ack to +

Fixed in yum-langpacks-0.4.2-5.el7

As per Comment 4, with yum-langpacks-0.4.2-7.el7.noarch:
- 'yum langinstall <LANG>' works as expected
- 'yum langlist' would only work if '/var/lib/yum/plugins/langpacks/installed_langpacks' file exist, else 'No langpacks installed' would be visible on the console as notified in Comment 7 and Comment 8
