Install on linux x64 (ubuntu 9x10 and 10.05) fails:
If I specify install to /opt, it asks for elevated permissions then bombs out with no error message.
If I specify install to your home folder it sometimes says it's downloading, sometimes doesn't say anything, sometimes says "404" and then bombs out.
I've seen other people with similar issues, saying it was solved by specifying the proxy. I don't have a proxy.
I did manage to install this in an ubuntu 9x10 x64 environment a couple of weeks ago, but it stopped working after about 20 minutes - and never let me log on anyway. Reinstall attempts similar to above.
