Title says it all.
Since upgrading from 17.10 to 18.04 Alt+Tab works fine i.e. switches apps cycling forward. But Alt+Shift+Tab does not switch apps backwards.
I went to Settings > Shortcuts and noticed that the shortcut for Switch applications is Super+Tab.
I tried Super+Tab and Super+Shift+Tab and they worked as expected, but i'm hardwired to use Alt+[Shift]+Tab. So I switched this shortcut to Alt+Tab.
Still Alt+Shift+Tab only switches forward, and not backwards.
Changing the shortcut to Super+Tab again works as expected for both forward and backward switching.
Any idea how to make the Alt+Shift+Tab work for backward app switching?

That's because Alt+Shift+Tab in Ubuntu 18.04 is blocked by another shortcut.
Run this command to free the Alt+Shift combination:
gsettings reset org.gnome.desktop.input-sources xkb-optionsI was able to resolve it using Gnome Tweaks GUI.
Open Tweaks and go to Keyboard & Mouse, then click - Additional Layout Options:as shown here, ans then uncheck Alt+Shift under Switching to another layout sectionas shown here
That fixed it for me.
1I use Ubuntu 18.04 with KDE and the answer from dima.rus helped me diagnose the problem: it was caused by a conflict with the shortcut for keyboard language switching.
What solved the problem for me:
- Change the
Main shortcutsinSystem Settings -> Keyboard -> Layouts -> Shortcuts for Switching Layoutwhich was Alt+Shift. EDIT: Do not set it to the otherwise rarely used Caps Lock as once I mapped and started using it, in some rare cases it caused the keyboard caps lock mode getting enabled and stuck (as indicated by the keyboard's caps lock light indicator), and forced me to reboot. EDIT: or instead of reboot, just startOnboard(the KDE on-screen keyboard) and use it to press Caps Lock virtually. - Set the
Reverseto Alt+Shift+Tab inSystem settings -> Task Switcher -> Main -> Visualization -> Shortcuts - Log out and in again to KDE
