[tde-users] Trying to install TDE on a (relatively) old Debian (9.13)

Hallo all. I'm re-setting up an old machine (a core 2 quad from 15 xears ago) and wanted to use a somewhat older distribution. I decided for Stretch and managed to find the online repos for older Debians. I then wantes to install trinity (from the website it seems 14.1.1 should be available, I also tried 14.0.0). I followed the instructions for repositories, however when I run install tde-trinity, I get dependency hell Several packages have unmet dependencies, for example Depends : tde-core-trinity (>= 4:14.0.0~) but it is not going to be installed Another weirdness is that aptitude has no installation candidate. I suppose apt or apt-get can be used instead. An idea? Thierry
