Spoke my friend tnx for your help!! But problem is still there, anyway last nigh i remembered that i heard something about red pill so i searched a bit and i learned how to use it and told huh lets give it a shot, so i used red pill and install that .deb file AND IT WORKS and the most important thing nothing goes wrong ...
but i still have a problem with xterminal when i type dpkg he allways sad unknown option -/ -g,-n etc...so bizzare, so i would like if someone know what's the problem to tell me how to solve it... anyway thank you very much again for your patience, and it would be nice if you would be able to resolve the problem whit xterminal for future operations...
