I'm feeling like a newbie despite my age when asking: what have I messed up when I get this reply trying to submit a build? mimmi$ rfpkg build You might want to run rpmfusion-packager-setup to regenerate SSL certificate. For more info see https://fedoraproject.org/wiki/Using_the_Koji_build_system#Fedora_Account... Could not execute build: Could not auth with koji. Login failed: HTTPSConnectionPool(host='koji.rpmfusion.org', port=443): Max retries exceeded with url: /kojihub/ssllogin (Caused by SSLError(SSLError(336236705, u'[SSL: LIBRARY_HAS_NO_CIPHERS] library has no ciphers (_ssl.c:2214)'),)) Running rpmfusion-packager-setup doesn't change anything. mimmi$ rpmfusion-packager-setup Setting up RPM Fusion packager environment ~/.rpmfusion.user already exists - skipping ~/.rpmfusion-upload-ca.cert already exists - skipping ~/.rpmfusion-server-ca.cert already exists - skipping Done! My own certificate is fresh: mimmi$ certtool -i < ~/.rpmfusion.cert | grep -A2 Valid Validity: Not Before: Thu Jan 24 22:26:14 UTC 2019 Not After: Tue Jul 23 22:26:14 UTC 2019 So what is it I'm doing wrong?
