Byobu in fedora hasn’t been updated in a while. The current fedora version is 4.4, while upstream has moved on to 5.17. That’s quite a lag we have. There’s a bug filed requesting an update by Upstream release monitoring, but it hasn’t received any human responses at all! It was filed in October 2011. Since I use byobu, 24×7, I’ve gone ahead and taken the initiative to update the package and submit the spec to the maintainer in the bug. I hope to see it updated soon. I’ve done a scratch build, you can use the noarch package if you are in a hurry like me. The srpm is available here, so you can build it for your fedora version too.

Howdy! Thanks for doing that. Please join us in #byobu on irc.freenode.net if you need some assistance from upstream. I don’t run much Fedora these days, but I do strive for as much cross-distro compatibility within Byobu as possible~

Thanks for keeping an eye out,

If you do this often, then apply for being a provenpackager. If you have done enough package reviews and maintain several packages as you do, this shouldn’t be a problem. Just file a ticket with FESCo for their consideration pointing to the work you have done so far that is relevant. Being a provenpackager would basically give you commit rights to all packages in the repo with the exception of Mozilla ones due to their trademark guidelines.
