I maintain our internal apt repo of Ceph, its build script generations some ddeb files, which is the debug symbol file. But reprepro cannot add those ddeb files, with errors like:
Unknown file type: 'a2e592c703334bc9f55a62f6fac267d8 135503940 debug optional ceph-base-dbgsym_14.2.7-75-g14b67dbc11-1_amd64.ddeb', assuming source format...
And below is my repo conf/distributions file:
Codename: bionic
Suite: stable
Components: main
Architectures: amd64 source
and reprepro version is 5.1.1
