I installed Virtualbox 5.0.10 in Fedora 23 workstation 64bit. Virtualbox is running well with installed extension pack.
When i try to update the system an error popups noticed:
"failure: repodata/repomd.xml from virtualbox: [Errno 256] No more mirrors to try.
http://download.virtualbox.org/virtualb ... repomd.xml: [Errno -1] repomd.xml signature could not be verified for virtualbox"
A look in the download section at "http://download.virtualbox.org/virtualbox/rpm/fedora" shows a subdir "23"; but when try to select this subdir the system redirects to the subdir "22" for Fedora22.
Please create subdir for Fedora23 with the needed and correct files in it.
regards
Gerhard
