I am running Linux Mint which is ubuntu/debian based. I got the error message: update-alternatives: priority must be an integer during installation of J9.4
The command in install-usr.sh causing the message was: update-alternatives --install $BIN/ijconsole ijconsole $BIN/ijconsole-9.4 9.4 The final parameter 9.4 should be an integer. Some standard way of converting between version number and an integer should be used. I used a three digit approach for myself: sudo update-alternatives --install /usr/bin/ijconsole ijconsole /usr/bin/ijconsole-9.4 940 This way it would get a higher priority than 9.03 --> 903 where just using 94 would be a lower priority. ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
