Hi, I've got the same problem. (on Dapper 6.06). I've added all repositories, and tried both synaptic and aptitude.
'sudo aptitude install -f libsdl1.2-dev' gave the following: ... The following packages are BROKEN: libglib2.0-dev ... The following packages have unmet dependencies: libglib2.0-dev: Depends: libglib2.0-0 (= 2.10.2-1ubuntu3) but 2.10.3-0ubuntu1 is installed. -- libsdl1.2-dev has trouble installing (dapper) because of libarts-dev dependancy https://launchpad.net/bugs/56939 -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
