Hello Mike
thanks for you quick response.
When I try to install tdm it complaines that "tdm requieres libr0 which is not an install candidate" so the dependensies could not be resolved. What to do next?
Do you have builddeps configured in your sources.list?
No, I hadn'd.
I give it a next try witn the builddeps enabled (I really didn't understand what the repo is good for - exept I have a longer time to wait) and now trinity was not deinstalled - but some other packages - for example gimp, freecad...
So many thanks for your help Rolf
