http://mirror.ppa.trinitydesktop.org/trinity/rpm/mga8/trinity-r14/RPMS/x86_6... refuses to install via urpmi, which claims bad MD5SUM file for both x86_64 and noarch. Fetched with wget, rpm had no problem upgrading from the installed mga7 version.
While on the subject of Mageia, when installing or upgrading, screen output during installation or upgrading is quite different for TDE packages vs. packages from other repos. Standard package fetch and install are accompanied by no blank lines output. With TDE packages around 5 out of 8 output lines are blanks, so roughly 2/3 of visual output is blank lines. This has been happening too long to remember, but for certain back into last year if not before.
