I don't have Fedora ... but I have Ubuntu and I got the .deb file from opera.com
I thought it would be as easy on Fedora too.
You could try doing an install using YUM.
Just download the .RPM file from the opera website. Just go here:
And where it says "Select distribution and vendor" you should choose "Fedora". Then there should be 4 selections down a bit.
Fedora Core 4 8.5 MB
Fedora Core 3 8.2 MB
Fedora Core (Other versions) 10.3 MB
Fedora 7, 8, 9, 10 8.5 MB
Make sure you select the last one ("Fedora 7, 8, 9, 10") and press the download button.
Do NOT check "Download this package in TAR.GZ format"
After you get the .RPM file, place it in your home directory and fire up a terminal, give it root access with "su", browse to your home directory and enter one of the following commands:
rpm -Uvh filename.rpm
yum --nogpgcheck localinstall filename.rpm
to install Opera. Remember to replace filename.rpm with the name of the actual .RPM file.
Hope this works. Good Luck!
