BTW,
when using the octave 5.1 copr repository on Fedora 30 I get:
# dnf upgrade
...
Upgrading:
qrupdate x86_64 1.1.2-17.fc31 group_scitech-octave5.1 79 k
qrupdate-devel x86_64 1.1.2-17.fc31 group_scitech-octave5.1 8.0 k
The weird part is the .fc31 suffix. Was that of a bad timing when branching?
:-)
Regards,
