Failed shortly after creating a new Copr project and uploading the spec file to start the build

Hello, after I tried to create a new project in Copr and started building by uploading the SPEC file in the new Copr project, the status showed ‘Backend worker is trying to acquire a builder machine.’ After one minute, the status showed ‘failed,’ and when I opened builder-live.log.gz, it showed 404 Not Found.

I’m experiencing the same issue. I’ve created a copr project yesterday, and more than 12 hours later, I still cannot build a package.

“Regenerate Repositories”, both through the web interface and copr-cli, have not effect. The repository does not have metadata:

$ curl -IL https://download.copr.fedorainfracloud.org/results/alpaco/resticprofile/epel-10-x86_64/repodata/repomd.xml -s | grep HTTP
HTTP/2 404

I think the problem is very annoyed.

Sorry for the issues folks,

for the record @march7thdev reported the problem here

The build of the RPM package in Fedora Copr failed, and opening builder-live.log.gz resulted in a 404 Not Found error. · Issue #4192 · fedora-copr/copr · GitHub

we were trying to debug it this week and I think with your report, we may have enough information now.
