I had O running on F21 without major issues. I did a fresh install (upgrade didn't work) of F23/KDE on a Lenovo W500. Now when I try to install O 4.1.1108 I get this message:
"Multiple packages exist that are not compatible with each other.
This is usually due to mixing packages from different software
"Could not depsolve transaction; 2 problems detected:
0. nothing provides opencpn-gshhs-low needed by opencpn-4.1.1108-1.fc23.x86_64
1. nothing provides opencpn-gshhs-low needed by opencpn-4.1.1108-1.fc23.x86_64"
O, the docs, and the plugins are all listed, but because of the missing dependency, nothing installs.
