Description David 2016-11-26 13:09:40 UTC

Description of problem:
When updating a rhel 7.2 container to 7.3, the update of glibc and glibc common, cause the locales to become unusable.

Locale -a, lists only C and POSIX.

This breaks a number of web applications that depend on the server having access to the same locale as the client. I first discovered it with an owncloud container.

The locale files under /use/share/i18n do get installed, and permissions are correct on them.

The config file in /etc does show (in my case) en_US.UTF-8, but locale command shows its using POSIX.

Selinux on host shows no denials, labels on the locale files are correct.

To fix, have to do a localedef build on every language. Or downgrade the glibc and glibc-common packages
localedef -v -c -i en_US -f UTF-8 en_US.UTF-8 

This does also occur on centos 7.2 containers being updated to their CR version.

Version-Release number of selected component (if applicable):
glibc-2.17-157.el7.x86_64
glibc-common-2.17-157.el7.x86_64

How reproducible:
Upgrade existing container from 7.2 glibc packages, to the 7.3 versions.
Locale -a does not show locales except c and POSIX

Steps to Reproduce:
1.use existing rhel 7.2 container
2.upgrade glibc and glic-common to the 7.3 versions (and all other packages if desired)
3.do a locale -a, or utilize something dependant on another locale

Actual results:
Only c and POSIX work 

Expected results:
All locales work

This is the intended behavior.  We wanted to make the container image locale removal persistent across updates.

Bug 1392855 comment 3 contains the steps required to obtain a full complement of locales.

I agree that this is a documentation issue.
