Situation

Updating the system through YaST --> Software --> Online Update.

The following two packages are included in the updates:

ruby2.5-rubygem-puma
release-notes-sles-for-sap

When installed, the release notes should be displayed in YaST, but it is not displayed.

In the log file /var/log/YaST2/y2log the following error is displayed followed by a backtrace:

2022-11-30 16:30:46 <3> localhost(11054) [Ruby] yast/wfm.rb:272 Client /usr/share/YaST2/clients /inst_release_notes.rb failed with 'Failed to load Module 'Language' due to: undefined method `missing_extensions?' for nil:NilClass' (RuntimeError).

Resolution

This is a minor issue that does not stop the packages from being installed. There is no need for any immediate action to correct the problem. The failure is only in displaying the release notes.

This issue has been reported to engineering and will be fixed in a future update to ruby.

Cause

Minor bug in ruby.

Status
