Could not launch 'Ubuntu One' Just upgraded from 10.04-->10.10 64-bit. When I try to launch Ubuntu One, I get a dialog that says:

Could Not Launch 'Ubuntu One"
Failed to execute child process "ubuntuone" (No such file or directory)

I uninstalled, and reinstalled. I also followed a process outlined here to completely purge. Still doesn't work.

Not sure how to trouble shoot this...

I have logged in via the website and added my computer.

I don't know where you're launching it from, but there has never been (to the best of my knowledge) a program called ubuntuone. Running ubuntuone-preferences (which is available in 10.10 in System › Preferences › Ubuntu One should bring up the old preferences application,

Maverick's Ubuntu One Preferences application

which should start everything running; if this is the first time you're running Ubuntu One on the computer, this should in turn pull up the Ubuntu Single Sign On application,

the Ubuntu Single Sign On client

Lastly should ensure that ubuntuone-launch (visible under the user-friendly name of "Ubuntu One") is listed and enabled amongst the System › Preferences › Startup Applications:

Startup Applications Preferences

Thanks... this totally helps. What was confusing to me is that I had an item in my Applications/System menu called Ubuntu One. This is probably a leftover from upgrades from prior versions of Ubuntu. Also, in looking at my startup, I discovered that there was no Ubuntu One instance... also, in looking at another machine, the correct command at startup is: /bin/sh -c '[ -d "$HOME/Ubuntu One" ] && ubuntuone-launch' – Kendor Mar 10 '11 at 15:06
whoops, fixed the u1launch vs ubuntuone-launch thing. The bit before ubuntuone-launch is to avoid running even that if the user has never used the service. – Chipaca Mar 11 '11 at 11:46
