how to solve altera_installer_gui problem

10.0_quartus_linux.sh: line 396: altera_installer/bin/altera_installer_gui: No such file or directory

during I installed quartus 10.0 in my Ubuntu 10.04.1 LTS I found this problem.

but, luckily I solved this problem. you must install the ´flashplugin-install´ which the altera_installer_gui needed, I guessed that it really required the adobe flasher supported.

:D
