I had some trouble installing Picasa 2.2 on OpenSUSE 10.3. After some tweaking it finally worked out. Here’s what I did:

  1. Install wine via YaST. Wine seems to be integrated in the Picasa archive, but anyhow this step was necessary.
  2. Download Picasa 2.2 at http://picasa.google.com/linux/thanks-rpm.html
  3. Install the rpm via sudo rpm -Uvh picasa-2.2.2820-5.i386.rpm
  4. Make a symbolic link for the wine libs via a sudo ln -s /usr/lib/wine /usr/local/lib/
  5. Edit /etc/sysconfig/ulimit and set SOFTVIRTUALLIMIT=0
    This change will only get active after a reboot. See also http://tr.opensuse.org/Wine for alternatives.
Hope it helps!
