DS-3095 we changed the way DSpace uploads its releases to sonatype. As part of the ticket we changed our documentation (https://wiki.duraspace.org/display/DSPACE/Release+Procedure) including the contents of the settings.xml. Unfortunately we didn't updated the poms of our language packs. The still look for credentials of the old server ids which aren't mentioned anymore in the documentation. Best solution would be to update the poms of our language packs to use the same upload method we are using for our main project.
