Ever since updating (actually a reinstall on a new SSD) Ubuntu from 14.04.1 to 14.04.3, I haven't been able to get the Unity Tweak tool working.

Even from the Software Center, it shows a missing canonical web apps dependency when attempting to run it. Trolling through various web sites, it seems I'm not the only one that can't figure out exactly what needs to be installed. There are a number of sites that provide multi-step procedures for getting it to work, but none of them have worked for me.

Has anyone else experienced this problem? Is there a known fix for this, or a specific set of dependencies that are known to solve the problem?

Thanks for any pointers.

Hi...

There might be. As an idea, please open a terminal and attempt to run the Unity Tweak Tool and then post the results. I think the command is...

Hopefully, this will tell us what's wrong and what files are needed, if any.

as so often (not you personally, cvalkan, it's a common newbie problem), this is the crucial point where you failed providing us with the information necessary to help you.

and no, we don't have the magical fix up our sleeves.

Sorry about the lack of specifics: There seems to have been so much written about this specific problem (set of symptoms?) that I assumed it was well known and neglected to give details. Having said that, there are really very few details available.

The dialog box that appears when running from the GUI says simply:
"The following schema is missing
com.canonical.unity.webapps
In order to work properly, Unity Tweak Tool recommends you install the necessary packages"

Of course it doesn't say what those "necessary packages" are.

When running Unity Tweak Tool from the command line (which I did do), the message is simply:
"Error: schema com.canonical.unity.webapps not installed"

Searching through Synaptic for "com.canonical" shows nothing at all, but searching for "unity.webapps" results in a very long list of possibilities - some obviously irrelevant, but several with similar but not identical names. I attempting installing as many of those as I could without getting the Unity Tweak Tool to react any differently.

The commentaries on several sites (as I said) didn't result in any success either - thus making any list of these unenlightening.

It's not that important. There are a few things I'd like to use it for, so I thought I'd take a shot and see if anyone knew precisely what it was looking for. I should also mention that I tried with both the "developer" version as well as the one included in the Ubuntu Software Center, but as near as I could determine, those are identical.

But thanks anyway.

ubuntu are really doing their worst to make linux the opposite of transparent.
should be called opaque linux really, people would probably even like the name.

and because normal configuration isn't possible anymore, people then have to install "tweak tools". welcome to windows mentality. tsk tsk.
(not that any of this is your fault, cvalkan.)

search the web on how to install software on debian-based systems with apt-get through the terminal.
this still works normally on ubuntu and is a 100% valid alternative to software center, last time i looked.
find out what unity tweak-tools dependencies and install-recommends are.
maybe you'll find the culprit.

Again, thanks, but even when installing with apt-get (which is actually what I prefer since I can have one big script for setting up a new installation), there is still no usable message to suggest that there is any difficulty at all. Strange.

I've been calling it "Obfuscated Linux" for some time, so I guess we view Canonical in much the same way ...

But Ubuntu is still easier to come to grips with than Xenix (Microsoft's early attempt to "fix" Unix), where they seemed to change things just for fun ...

Like I said, however - it's not that big of a deal; it's just annoying.

Thanks again.

This was my thought as well, try reinstalling the software.

If that doesn't work, you can also try repairing any broken packages using the commands mentioned here.

Regards...

this.
