A problem has occured when checking for updates - 16.04

Question

There's red circle with white minus sign in the middle that says that a problem has occured when checking for updates. I'm also unable to open "Software & Updates" and "Software Center". I have tried uninstalling and reinstalling the software-center, but it gives me this error when I try to open the software-center via terminal.

File "/usr/bin/software-center", line 140
    print time.time()
             ^
SyntaxError: invalid syntax

Appears to python2 code. Is it using python3 to interpret?

when i tried software-properties-gtk

it gave me this

  File "/usr/bin/software-properties-gtk", line 32, in <module>
    import aptsources
  File "/usr/lib/python3/dist-packages/aptsources/__init__.py", line 3, in <module>
    import apt_pkg
ModuleNotFoundError: No module named 'apt_pkg'

maybe there's something wrong with my python as I just updated python3 to python 3.7.4 — Michael L, Aug 31 '19 at 03:59

Hey This quetion seems to have been answered here but try running

sudo apt-get install --reinstall python3-apt

The error is primarily because of library apt_pkg.cpython-35m-x86_64-linux-gnu.so not being present in /usr/lib/python3/dist-packages.

Removing and reinstalling should help.

If that doesn't work, I would recommend taking a dive into your system logs.

thank you @https://askubuntu.com/users/857799/vikas-kapdoskar in advance

i see it in that /usr/lib/python3/dist-packages – Michael L Aug 31 '19 at 04:15
Try running sudo apt auto-clean sudo apt auto-remove and then sudo apt update – Charles Wilson Aug 31 '19 at 04:28
apt_pkg.cpython-35m-x86_64-linux-gnu.so``` I have two versions. is that normal? There's a symbolic link to the 34m version – Michael L Aug 31 '19 at 04:50
try ------------- cd /usr/lib/python3/dist-packages sudo ln -s apt_pkg.cpython-{35m,34m}-x86_64-linux-gnu.so – Charles Wilson Aug 31 '19 at 05:04
and typically no, when you see double when it comes to APT, it's never really good – Charles Wilson Aug 31 '19 at 05:05
well it i fixed it by sudo ln -s apt_pkg.cpython-{35m,36m}-x86_64-linux-gnu but I have another error for dbus for another post lol – Michael L Aug 31 '19 at 05:44
