Euca2ools can be installed on Debian squeeze using binary DEB packages. To install them, add our repository to the list of repositories for your system to use. To do so, add somewhere in /etc/apt/sources.list file the following line:
For 1.1:
deb http://www.eucalyptussoftware.com/downloads/repo/euca2ools/1.1/debian squeeze contrib
For 1.2 (including release candidates):
deb http://www.eucalyptussoftware.com/downloads/repo/euca2ools/1.2/debian squeeze main
And then run:
apt-get update apt-get install euca2ools python-boto=1.8d-1
You will have to type "Y" if you see a warning like,
WARNING: The following packages cannot be authenticated! ... Install these packages without verification [y/N]? y
After installation you may remove the entry from sources.list if you don't want to update Eucalyptus packages automatically.
