Couple of days back, I had to sync some photos from my laptop to Picasa web albums. This was the first time I used Picasa app after installing Fedora 12 in my laptop.
I clicked on the "Sign In to Web Albums" and entered my gmail username and password and got log in failure message. The log in window returned immediately showing "Login failed - Please try again later". The error was thrown in less than a second which was ample reason for me to believe that that this is a problem at my end, not at gmail end.
Searched the web and got the solution suggesting to install "openssl-devel" package on my laptop.
# yum install openssl-devel
Tried to sign in to the web album again, but unfortunately still getting the same error message.
Banged on my head for a couple of minutes and finally realized that Fedora 13 running on my laptop was x86_64 and picasa is a 32 bit application and I must install openssl-devel.i686.
# yum install openssl-devel.i686
I was really happy after that. Everything worked as expected and my engagement photos are now live on picasa.
