I am trying to use a yum proxy to Centos 8 EPEL, but I keep getting 404’s on xml.xz files. The only entry in the Nexus log is that is about “An exception occurred determining the content type of asset”. I have tried to disable Strict Content Type Validation but it does not help fix the issue.
Is this a bug, or am I doing something wrong?
Nexus version:
Nexus OSS 3.21.1-01
Client error:
Cannot download ‘https://reposerver/repository/epel_mirror_2/8/Everything/x86_64/’: Yum repo downloading error: Downloading error(s): repodata/af449e2ed3e8482345740f973eab1fd3054df95d9eb701800529c05c6c9a1e31-prestodelta.xml.xz - Cannot download, all mirrors were already tried without success.
(showing 404 when trying from a browser)
