Error indexing packages

When I updated to version Octopus.3.11.16-x64 and today to Octopus.3.12.4-x64 indexes of the package repository were re-indexed. In the task log it runs a task after installing both versions. The task is called “Re-index built-in package repository”.

When running I get a lot of warnings with the following message:

Error indexing package ‘D:\Octopus\Packages<mypackagename>.20161221.1.0.nupkg’.
Central Directory corrupt.
System.IO.InvalidDataException: Central Directory corrupt. —> System.IO.IOException: An attempt was made to move the file pointer before the beginning of the file.

When I look at the file it does exist on disk at the specified path, BUT the size is 0 bytes.
This task took about 12 minutes to complete.

My questions:

  1. Is this going to be a problem?
  2. How should I deal with those 0 byte files (more then one file, didn’t count them)?
  3. How did those 0 byte files get there?

Thanks for helping out.


Thanks for getting in touch!

These errors shouldn’t cause any problems, looking at the code, we just log the exception and move on to the next package.

Are these 0 byte files new? The one you gave as an example looks to be from late 2016 (going by the package version)?

Not sure where these 0 byte files would’ve come from, how do you package / push your files to Octopus? Maybe there was an issue when pushing / uploading these packages.

I hope that helps!

Thank you and kind regards,

We’re deploying with Visual Studio Online to octopus. Can you make the error message less drastic


I’ve raised this GitHub issue to have improve the error message.

Thank you and best regards,

Thanks for improving that error message. Last question, can I delete the 0 byte files without consequences?

Yes, you can remove the 0 byte files as they have somehow been corrupted and we won’t be able to do anything with them, so they are just going to create noise in your logs.

Thank you and best regards,
