Linuxtools archiving lost content

It looks like the archiving process for Linuxtools lost some content.

The following folders are missing the files that were supposed to be in the roots of those folders (expected artifacts.jar artifacts.xml.xz content.jar content.xml.xz p2.index)

• https://archive.eclipse.org/linuxtools/update-7.5.0/ (this one also has an extra nesting level)
• https://archive.eclipse.org/linuxtools/update-7.7.0/
• https://archive.eclipse.org/linuxtools/update-docker-4.5.1/
• https://archive.eclipse.org/linuxtools/update-docker-4.6.0/
• https://archive.eclipse.org/linuxtools/update-docker-4.7.0/
• https://archive.eclipse.org/linuxtools/update-docker-5.0.0/ (this one looks ok, but has a dodgy subdir that looks like the broken ones)
• https://archive.eclipse.org/linuxtools/update-docker-5.1.0/ (same as 5.0.0)
• https://archive.eclipse.org/linuxtools/update-docker-5.2.0/ (same as 5.0.0)

Is there a backup of this available? Is there any way to track down what may have happened here. #754 (closed) indicates that some problems occurred during a recent archival.

If there is no backup or idea why this may have gotten lost, I see that there are zip files for each of those releases that look ok (e.g. https://archive.eclipse.org/linuxtools/linuxtools-docker-4.6.0.zip -> https://archive.eclipse.org/linuxtools/update-docker-4.6.0/). Can we get them unzipped to replace the broken folders?

This may relate to #754 (closed) and has been reported to linuxtools-dev https://www.eclipse.org/lists/linuxtools-dev/msg04522.html
