So lot of questions asked. I’ll try to answer some to best of my ability.
When OpenMandriva was formed from the ashes of Mandriva part of the agreement was that we can not call it Mandriva. Legal stuff as I understand.
Any reason you did not install our latest version OM Lx 4.1? Also see the announcement.
Your first assignment is to find and utilize the Software Repository Selector.
Reason is that OM Lx by default only has what we call “main/release” and “main/updates” repos enabled by default. For maximum availability of software there are 3 others. This is explained more here and here. Screen shot of Software Repository Selector:
The OM Lx documentation right now is a work in progress that needs improvement. What we have is found in the OM wiki and the Resources section of this forum. (The URL for the OM wiki is temporary while Infra team is working out web hosting issues.)
There soon will be some additional work done on our documentation.
So am I.
Hope this information helps.
