Hello, I tried to build kontact-trinity on Debian Bullseye with the sources I got from the Trinity repos. At first I used "apt source kontact-trinity" to get the sources. Then I ran "apt build-dep kontact-trinity" to get the dependencies. The next step was to run debuild (from the devscripts package). Finally, I tried to install all the deb-packages. For most packages that was no problem, but I couldn't install tdepim-trinity-dgb, tdepim, kmail, kmailcvt, korn, and kontact (I don't write the whole package name, but they look like kontact-trinity_14.0.11-0debian11.0.0+0_amd64.deb) because dependencies are missing. The messages look like this one: "[...]dpkg: dependency problems prevent configuration of kontact-trinity: kontact.trinity depends on kmail-trinity; however: Package kmail-trinity is not configured yet. dpkg: error processing package kontact-trinity [...]". I expected that I would be able to install all packages because apt source and apt build-dep should get all packages I need to install kontact-trinity. Can you help me with this problem? Greetings, Christoph
