New XBPS 0.25 repository format
Starting with XBPS 0.25, the repository format has been changed to a single compressed file. This will cause troubles if you are upgrading from an old version, and you will encounter errors with missing packages when installing and/or upgrading.
Therefore you must update XBPS before continuing to avoid the missing package errors:
$ xbps-install -Su xbps
This will update XBPS to the latest stable version stored in the old repository format.
After upgrading XBPS to
>=0.25 you can safely install and upgrade packages normally.
