Which package should I install in Ubuntu 9.10 before I manually can install Parallels Tools 5? In the help function of Parallels there are a few dependencies mentioned, but I don't know how they are called in Ubuntu. And one I can not found in Ubuntu 9.10. This is mentioned in help: Parallels Tools can be installed in Linux guest operating systems that comply with the following requirements: glibc 2.3.4 and later libstdc++ 3.4.6 and later (libstdc++.so.6) gcc 3.4.6 and later (including C++ support) make 3.80 X Window System X11R6.7, X11R6.8, X11R6.8.99, X11R7.0, X11R7.1, X11R7.2 (1.3), X11R7.3 (1.4) kernel sources or development package But the tools are installed with a clean install of Ubuntu 9.10 but I can not manually install Parallels Tools because it hangs on installing and Ubuntu 9.10 will not boot after.
