RPM feed can't be browsed

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

Hi,

it somehow healed "itself"? This morning it presented me with Issues in the feed and I started a reindex. Now I can browse the feed again.

The data was originally uploaded from a build in jenkins through curl:

curl --parallel --user usr:psw --config config.txt

with the config.txt file like this
config.txt-Schema:

url = "https://<proget_url>/rpm/archive_name"
upload-file="rpm_1"
.
.
.
url = "https://<proget_url>/rpm/archive_name"
upload-file="rpm_13861"

Hi @wechselberg-nisboerge_3629 ,

Given how you uploaded the file, the only scenario that I could see this happening is if the file on disk is somehow corrupted. For example, if you were to locate one of the .rpm files on disk and change a few bytes with a hex editor, I would expect this exact error to occur.

A feed reindex could would never fix this and obviously files cannot "heal themselves". However, this is exactly how hardware behaves, so I would look into that.

Thanks,
Steve
