I recently found that Picasa for Linux** no longer exists in the Google/Linux repository, so I had a Google around and found a few guides on how to install it with Wine. There were a few different guides, but I got errors as my machine is 64bit and didn't have all the necessary Wine/Windows libs etc..
**Just to be clear, Picasa was always a Windows package, but the Google/Linux download came prepackaged with Wine.
Wine and Winetricks
First you need to install Wine, and then download Winetricks
sudo apt-get update && sudo apt-get updateWinetricks
sudo apt-get install wine
wget http://winetricks.org/winetricks**NOTE on Debian Wheezy (Testing)
sudo mv winetricks /usr/local/bin/
sudo chmod +x /usr/local/bin/winetricks
Artur posted in the comments that you may need to install libwine-cms as mscms.dll is needed.
sudo apt-get install libwine-cmsDownload Picasa 3.9 for Windows
cd && wget http://dl.google.com/picasa/picasa39-setup.exeDownload Internet Explorer 7 64bit as There is no 64bit IE6
Without it, you won't be able to login to your Google account.
**Note To Install ie7
You may have to symlink "wineserver" to /usr/local/bin, as suggested by Simon in the comments.
sudo ln -s /usr/lib/wine/wineserver /usr/local/bin/wineserver
Place it in your Winetricks IE7 cache directory:
mkdir -p /home/YOU/.cache/winetricks/ie7
cp /home/YOU/Downloads/IE7-WindowsServer2003-x64-enu.exe /home/YOU/.cache/winetricks/ie7Download Cabextract
It is needed to extract Windows Cab files.
sudo apt-get install cabextractRun the Winetricks script:
64bit DependencyBefore running Picasa setup with Wine you need an extra lib:
sudo apt-get install lib32nss-mdnsFinally Run the Picasa setup
That's it, now you're good to go with Picasa!
