You are right about the website, but it is old information and has not been
updated. I lived through the changes and have MEPIS 8 installed, so I know the
repos well. MEPIS is a one person operation and Warren was ill through this
period, so perhaps it was not a high priority. It emtions 2006, but not beyond
that.
This is the Wikipedia section on this period:
MEPIS was designed as an alternative to SUSE Linux, Red Hat Linux, and Mandriva
Linux (formerly Mandrake) which, in the creator Warren Woodford's opinion,
were too difficult for the average user. MEPIS's first official release
was on May 10, 2003.
In 2006, MEPIS made a transition from using Debian packages to using Ubuntu
packages. [1] SimplyMEPIS 6.0, released in July 2006, was the first version of
MEPIS to incorporate the Ubuntu packages and repositories.
SimplyMEPIS 7.0 discontinued the use of Ubuntu binary packages in
favor of a combination of MEPIS packaged binaries based on Debian and
Ubuntu source code, combined with a Debian Stable OS core and extra
packages from Debian package pools.[2]
If you install MEPIS all evidence of Ubuntu is gone. While it mentions Ubuntu
source code in Wikipedia, there is nothing that faintly resembles Ubuntu. So I
am not sure what they are using re: Ubuntu since Ubuntu and MEPIS have the same
original source, Debian. Debian has long complained about Ubuntu's lack of
upstream contributios, but that is no longer the case. They now contribute
upstream and this could be what the wikipedia article refers to.
I admit it is all confusing, which is one of the reasons that I moved from MEPIS
to Ubuntu in 2006.
