I recently updated my Macbook Pro 2015 to macOS Sierra. Right after it showed me a couple of updates on the App Store. However, when I try and update them I get the following errors. Its been showing me these errors for the last 5 days now. Can anyone please help? --- Post Merged, Nov 12, 2016 --- I think I have this resolved. I selected "Check for unfinished downloads" from the Store menu in the App Store. It asked me to login again and then switched my store account to my native country. After that it wouldn't show the updates in the Updates section (it just kept saying "Checking for Updates") but under Purchases I could see all the apps installed on my App from the Store and I could update my apps from there.
