it successfully install without any error only so one warning (We don't care about warning ). At that time i thought dropbox installed in my system and i can sync my folder but when i opened dropbox and click on splash screen, it show me following error.
Shit i did not get any preference window for set proxy so now time to google. I googled this problem around 1:30 hour and ask my friend also but at last i got a blog in which that personupload a tar file. That tar file contain all the file which dropbox download from the net and make a .dropbox-dist folder in your home directory.
Installation steps :
1. Download dropbox rpm from its main site and install it using command "rpm -ivh package-name"
2. Download off-line file from here .
3. Extract the off-line file and its extracted name ".dropbox-dist" so it is a hidden folder you press "CTRL+H" for see that folder and copy or cut it, then paste it in your home folder as same extension. DON'T RENAME IT.
4. Now you create a dropbox account from here .
5. Now go to Application -> internet -> dropbox , now a dropbox icon is appear on your panel right click and first set proxy if you are under proxy server.
Congrats you install dropbox successfully.
