I am using the precise beta and totally hate the new qt based ubuntu one control panel. I would like to switch back to the old, pretty, gtk based control panel, and expect that it would still work. However, I don't know how to install the old control panel from the oneiric repo without manually installing all dependencies from the ground up. How can I install it without dependency checks?
The old ubuntuone-control-panel-gtk code is no longer available in the trunk source tree, or in the Ubuntu archive. The package is now a transitional package, so that people upgrading from older versions of Ubuntu to 12.04 will automatically get the ubuntuone-control-panel-qt package installed (as it is not part of the default install, due to CD size limitations), rather than having the ubuntuone-installer pop up asking them to install Ubuntu One again.
If you really must have the older version, you can tell apt to install a specific version of a package like:
If it is still in the archive or your local apt packages cache (packages apt has downloaded before), it should install it. You can also download the older package from Launchpad and install it directly, with gdebi, dpkg, or similar. However, be aware that installing the older control panel will break system integration, and is totally unsupported. You get to keep both pieces if something breaks. :)
