I tried reinstalling software center (after apt update) and got errors.

Notice that some Loki Release repositories do not have a Release file.

I upgraded Freya to Loki. I noticed numerous errors in the log about not having permissions, as well as the missing release files in Update Manager.

Here is the syslog output:

File "/usr/share/software-center/softwarecenter/db/__init__.py", line 6, in <module>
    from .debfile import DebFileApplication, DebFileOpenError
  File "/usr/share/software-center/softwarecenter/db/debfile.py", line 25, in <module>
    from softwarecenter.db.application import Application, AppDetails
  File "/usr/share/software-center/softwarecenter/db/application.py", line 28, in <module>
    import softwarecenter.distro
  File "/usr/share/software-center/softwarecenter/distro/__init__.py", line 201, in <module>
    distro_instance = _get_distro()
  File "/usr/share/software-center/softwarecenter/distro/__init__.py", line 176, in _get_distro
    module = __import__(distro_module_name, globals(), locals(), [], level)
ImportError: No module named "elementary"

One: "Input error: No module named "elementary"

First of all the only way to upgrade Freya to Loki is to reinstall elementaryOS. So if you didn't fresh install Loki I suggest you to do so, to prevent errors like this one to happen.

Second, in Loki the Software Center was removed to give place to AppCenter.

  • I did an install over Freya. The icon for Software center still shows in the dock and in the menu. Would it help to repeat the installation?

  • As I told you earlier, you have to reinstall, which means make a backup of whats important to you and when installing Freya format each partition before installing Loki. That's is the only and official way to do it. Commented Sep 17, 2016 at 9:32

Having no software center and not being able to get Synaptic Package Manager is like having arms and legs chopped off. We don't all use phones for Internet, quite a lot of serious users use a desktop. What's the point of having to mess with terminal to get the things that you need after installation? I have to go back to Ubuntu until I find an opsys I am happy with. The things I like are pantheon look and the old Midori. I shall miss those
