All matches were filtered out by modular filtering for argument: scala
Error: Unable to find a match: scala
If I try to install a package that depends on scala:
# dnf install ant-scala
Last metadata expiration check: 0:32:13 ago on Mon 06 Jan 2020 13:31:04 AEDT.
Error:
Problem: package ant-scala-2.10.6-16.fc31.noarch requires scala = 2.10.6-16.fc31, but none of the providers can be installed
- conflicting requests
- package scala-2.10.6-16.fc31.noarch is filtered out by modular filtering
(try to add '--skip-broken' to skip uninstallable packages)
How can I find out why scalar is being "filtered out by modular filtering"?
This is an updated fc30->fc31 system. A clean install of fc31 will install scala OK.
