I'm on dual booth with Windows 7, and AppCenter does not update or install anything; it just hangs on "waiting in queue". There is a working Internet connection, and I have another non-dual boot PC where AppCenter works just fine. Any ideas what I might be doing wrong?
I'm on dual boot (UEFI) with Windows10 and AppCenter installs work fine here (Installed a fresh copy yesterday)
There was an issue with the appcenter not so long ago (issue description) so you can follow these instructions.
Have you updated the OS
sudo apt update
sudo apt upgrade
Can you install via apt or apt-get? -------------------------------------------------17/05/17 UPDATE: I run the upgrades and the appCenter is still working
