I have just installed Ubuntu 16.04 32-bit.
When I opened its software store, I found that it's not showing the apps I installed in Ubuntu 15.10 like Clementine, Gdebi package installer or synaptic package manager, dconf, acetoneiso etc.
I need these applications. How can I install them?
The Ubuntu Software app in Ubuntu does not have the same software in it as the classic Ubuntu Software Center has. Not only is there missing software in the Ubuntu Software app, but the Ubuntu Software app also has some GNOME software in it that the Ubuntu Software Center doesn't have. To be sure of finding all the available software, you need to have both the Ubuntu Software app and the Ubuntu Software Center installed. If you want to broaden your search to include snap packages in Ubuntu 16.04 and later, you have to search in the terminal to find available snap packages too.
Ubuntu Software and Synaptic are the top two software apps in Ubuntu 18.04 and they complement each other in functionality.
It should be noted that because software can be installed from both of these two GUI applications, only one of the following two applications should be opened and used to install software at the same time.
Ubuntu 17.04 doesn't have Ubuntu Software Center in its default repositories. Synaptic Package Manager works fine in Ubuntu 17.04 and shows all the apps like Ubuntu Software Center does, however Synaptic does not provide the same rich user experience as Ubuntu Software.
When I searched for a way of improving the package search functionality in Ubuntu 17.04, I found Debian Package Search (packagesearch). Debian Package Search is a GUI for searching packages and viewing package information. Debian Package Search can be installed alongside Synaptic and Ubuntu Software to add additional search functionality to Ubuntu 17.04 and 17.10 (discontinued in 18.04 and later).
Search in Debian Package Search can be done by:
Additionally a lot of information about the packages is displayed, including the files belonging to them.
Ubuntu Software Center works fine in Ubuntu 16.04 and shows all the apps as it did in earlier versions of Ubuntu. Ubuntu Software Center can be installed in Ubuntu 16.04 and Ubuntu 16.10.
sudo apt install software-center
The new software center was a mess for the first couple of hours, and this faulty version doesn't seem to refresh itself while it keeps running in the background even after you've closed the window.
You can force quit it by invoking
killall gnome-software
When you start the software center again it should update and look like a proper software center.
It's actually a very nice program now.
I have experienced the same problem. Until it is fixed, I suggest using Synaptic package manager. All the packages are available there and it works very well.
sudo apt-get install synaptic
sudo apt-get install gksudo
gksudo synaptic
(it is safe to skip a step if already installed)
Search for your package (application) by name and right click and mark for install. Then click apply. You can uninstall by the same method.
I had similar issues and I tried all the solutions mentioned above and no luck! Every time I click on the Software Center icon, it shows very few applications and I don't find common applications like Geany, Filezilla, and so on. On my laptop, I have the same version of Ubuntu 16.04 and there I find all applications by clicking on the Software Center icon. Finally, I started the Software Center from the command line and it loaded with all applications, thank God!
Solution (Open software center from terminal instead of clicking on the icon):
shoeb@shoeb-OptiPlex-980:~$ software-center
If the method above doesn't work you can try this:
First, open the terminal and type this:
ps aux | grep apt
You will get a result in a table form, we are interested in the apt requests that contain the words http or software in them.
Once you find it, look at the second column. For example this is how it might look like:
username 2514 0.0 0.0 21376 948 pts/1 S+ 22:37 0:00 apt-http
The results you get will be similar, but not exactly the same.
Now, we want the second column for the above result: that's 2514 for me. Add it here (put the number you just got instead of 2514)
sudo kill 2514
Repeat the commands until you get no more unnecessary requests (chances are you will have to do it only once).
Now start the ubuntu software and it should work!
Removing unused dependency packages solved this problem for me.
To do this
sudo apt autoremove and press Enter.I hope it works as well for you as it did for me. Unfortunately I have no idea which package caused this problem.
