Muon software center - search not working

[thany]

I tried to find some packages that should bleedingly obviously be in the repositories exposed by this program. I tried to find firefox and 7zip, and the search cannot find them. They are listed, just not found by attempting the search function.

What's going on? Even when I search for "firefox" the search turns up zero results. How can this be? It's clearly in the list...

Have you tried fetching updates? I have not seen this happen myself. Of course I do not see how to do this using the Software Center, so you may want to try doing this using the full Muon package manager to see if updating the package list fixes this.

I would say the search function is a bit strange in it (software center) however I did just use it for the first time and firefox did pop up before I got threw typing it , 7zip did not but to be accurate it is p7zip for us
use the muon package manager

I'll try it after updating then.

Mind you, "p7zip" has "7zip" in it. I would fully expect it to turn up, especiallyif nothing else matches - because turning up zero results is never better than turning up approximate matches.

Much like Ubuntu's Software Center, Muon Software Center does not list the full number of packages available, I believe. I can see something like p7zip (from the Universe repo - not supported by Ubuntu) not showing up, but Firefox should, which is why I suggested refreshing th package list, as I do not know when and where the Software Center updates its package list

This:

sudo update-apt-xapian-index -f

will force a rebuild of the package index that Muon uses.

This:

sudo update-apt-xapian-index -f

will force a rebuild of the package index that Muon uses.

Yeah, but that should not be necessary for a user-friendly GUI, right, or the for the users thereof?

[SteveRiley]

Show me the GUI button that says "Rebuild Muon index"

[claydoh]

:P

[vinnywright]

This:

sudo update-apt-xapian-index -f

will force a rebuild of the package index that Muon uses.

you would expect muon software center to use the same package index that muon package manager dose ,,,,,and show the same software ,,,,,,that is all that is avalable from the sources you have enabeld ? as should muon discover !!

All three elements of the Muon suite rely on the same Xapian index:

muon-installer is the Muon Software Center. It intentionally doesn't display everything in the archive; instead, it limits the choices to "typical" end-user applications. muon is the Muon Package Manager, which exposes the entire set of all available packages. And no, I don't know what the decision factor is for deciding what goes into and what stays out of the Software Center

Normally, the Xapian index is self-maintaining. But I suppose it could become corrupt somehow, so knowing how to rebuild it could be useful.

[thany]

Even if the index would have gone corrupt (I can't check right now, sorry) it would be a software error, since this is a fresh install (and I do mean fresh) and the computer hasn't crashed or anything.
