I wonder why this bug is there till now. I have almost no experience with debian, and absolutely no idea of citadel, but I suspect what is the cuase why it hangs. I did manage to install the package with the following steps: (1) I have to xterms with ssh to the server (2) run in one of them: apt-get install citadel-server (3) wait until in hangs (4) run in the other: sendcommand "CONF PUTVAL|c_default_cal_zone|UTC" (5) Search with "ps ax | grep citadel" the PID of /usr/lib/citadel-server/setup -q (6) run: kill PID -- the above process, the hanging proces (7) run: /usr/lib/citadel-server/setup The last program is interactive. The quiet version "setup -q" ist probably run in a script that make errors filling values. I discovered this after interrupting apt-get many times and braking it, and each time making strange things to make apt-get work again, until I discovered this solution. After this short experience with debian I am waging to install other OS. Rod.
