Background： ・We plan to upgrade Sonatype Nexus from version 3.59 to 3.79. ・Since we are migrating from OrientDB, we understand that it is necessary to upgrade to 3.70 first as an intermediate step. ・Due to the requirements for the number of users, we need to migrate to PostgreSQL instead of H2. ・We are currently using an S3 blob store. ・The server in use is running RHEL 8.1. After upgrading from version 3.70.4 to 3.79.1, migration and startup completed successfully. However, three types of errors occurred in the nexus.log, and materials in the target blob store are no longer accessible. The upgrade procedure and error logs are detailed below. Based on the error content, we believe this is a similar issue to the following: > > > I have upgraded to 3.74 from 3.71 runnin gon CentOS 8 with Java 17 and H2 databa…se. > I am using S3 as my blob store. > > During start of nexus 3.74 saw errors which looks like connection issue to S3 storage. > > \image > > Once restarted I went to blob store edit screen and clicked on save and got below error. > > \_An error occurred saving data. ERROR: (ID 845202fa-50d7-4ff3-a41f-388dfbc1c64c) java.lang.IllegalArgumentException: Unexpected end of base64-encoded String: base64 variant 'MIME-NO-LINEFEEDS' expects padding (one or more '=' characters) at the end. This Base64Variant might have been incorrectly configured\_ > > \image > > I have tried to update the Access Key ID and Access Key Secret but the error is still the same. I verified the Key and Secret, both are correct. > My S3 blob store does not have any encryption enabled > \image Questions: ・What is the cause of this error? ・Could you please advise on how to resolve this error?
