RPM feed can't be browsed

[wechselberg.nisboerge_3629]

We are hosting an RPM feed, which can't be used in the UI anymore, because if only shows this error:

This is logged in the Diagnostics Center.

The archive entry was compressed using an unsupported compression method.

Hi @wechselberg-nisboerge_3629 ,

This error is the result of a "bad rpm package" (basically one that is compressed using a method we don't support) getting accepted into ProGet. It should have been rejected on load -- if ProGet cannot open a package file due to unsupported compression, then I'm not sure how it would have indexed the package.

You should be able to find which package it is by going to the "packages" tab at the top of the UI; when you click on the rpm package, it will give a similar error.

How did you add this package? What package is it? This is an error we can definitely fix if we can figurer out how you got the unsupported package in there.

Thanks,
Steve
