Linux Mint and Ubuntu don't get along very well, something that is popular even though they have similar philosophies and seek the same thing: to simplify Linux for the most novice users. The fact that between the Ubuntu Community and the Kubuntu Community there are not very good relations.
This is normal within large projects such as Ubuntu, Kubuntu or Linux Mint. However it is not normal or known the fact that Kubuntu and Linux Mint come together to bring their versions forward of their main distributions.
The Kubuntu team repository now supports Linux Mint KDE Edition
We have known this collaboration thanks to a post that Clem, Linux Mint leader recently made. In this post, he appreciates the work and help received from the Kubuntu Developer Community to bring out the KDE Edition of Linux Mint. What's more have made it possible for their Backports repository to be used in Linux Mint KDE Edition, so that your users have the latest version of Plasma, a version that will improve the problems that still exist in the latest versions of Plasma 5.
Later, Linux Mint team will bring Plasma 5.8 to their KDE edition, but at the moment it will not arrive due to its instability and its incompatibility with the new versions of Linux Mint. We have been talking to you for a long time about how to add this repository in your Kubuntu, the process is similar if not the same in Linux Mint (but it does not work in LMDE as it is based on Debian).
It seems this news will fill Linux Mint KDE users with surprises and the latest versions of Plasma, but it also seems that Kubuntu and its developers are launching a warning or a wake-up call to the guys at Canonical, a tough wake-up call. In any case, it is positive that large projects collaborate with each other to provide the end user with the best Gnu / Linux software Do not you think?
