When I run 'dnf check-update', I get an error saying dnf failed to synchronize cache for repo 'updates' : $ dnf check-update Error: Failed to synchronize cache for repo 'updates' from 'http://download.fedoraproject.org/pub/fedora/linux/updates/23/x86_64/': Yum repo downloading error: Downloading error(s): repodata/c49b5dbbcb4aec26fcd2147ec683889472d67054e85ef72898e391d254dfc069-filelists.xml.gz - Cannot download, all mirrors were already tried without success; repodata/fb6a6253a20448a1cf842e96278b6e8d187a330dc63c6f51a90ba0033b9d7514-prestodelta.xml.xz - Cannot download, all mirrors were already tried without success It works only with option '-C' present. $ dnf -C check-update Last metadata expiration check performed 3:32:17 ago on Thu Feb 11 05:24:23 2016. arprec.x86_64 2.2.18-1.fc23 updates hplip.x86_64 3.15.11-6.fc23 updates [...] Version-Release number of selected component (if applicable): dnf list dnf* Last metadata expiration check performed 0:04:50 ago on Thu Feb 11 08:48:38 2016.

Hi, This was probably due to the mirror simply being down at the time. I've just tried this with a .repo config using the very same baseurl and it worked for me (it fetched the metadata successfully). If you hit this issue again, please consider filing a ticket against Fedora Infrastructure, as described here: https://fedoraproject.org/wiki/Infrastructure/Tickets
