I have Loki installed on my laptop and desktop. Appcenter works fine on my laptop, but it doesn't on my desktop. It doesn't show any updates, that tab is empty. I can browse and search for software, but everything has an "install" button, even programs that are already installed. Pressing install results in either Appcenter freezing, or displaying "waiting" forever.

I can install, remove, and update things just fine from the terminal. I've tried uninstalling and reinstalling appcenter, updating apt, and everything else I could find here on Stack Exchange. Empty update tab Here's the empty update tab, no updates or current software is displayed. Files is not installed, according to Appcenter According to Appcenter, Pantheon-files is not installed (it is)

  • The same problem. Noticed it after last system update. I have tried to do ations from the comment above but no result. AppCenter works only when I reboot sysytem and choose the previous version i.stack.imgur.com/Gc2if.png Apr 9, 2017 at 17:51

The elementary team has issued instructions on how to fix this (see https://medium.com/elementaryos/important-update-released-501c9d9f28b). Apparently there was a mismatch between AppCenter and packagekit.

sudo apt update

sudo apt install packagekit


I had this same issue and this helped:

1.) remove the eOS repo:

sudo add-apt-repository --remove ppa:elementary-os/daily

2.) update/upgrade repos

sudo apt-get update && sudo apt-get upgrade

3.) reboot

4.) add the repo back

sudo add-apt-repository ppa:elementary-os/daily

5.) update/upgrade repos

sudo apt-get update && sudo apt-get upgrade

this should upgrade the AppCenter app as well and it should work.

If not, try rebooting - it might help. For me the AppCenter sometimes works, sometimes doesn't... I just reboot and it's probably fine after the next boot.

    This is quite a scary move to make: "Do NOT install this PPA if you want a tested running system, this PPA contains the newest and most unstable development of elementary, it's useful only if you are a developer and are not afraid to encounter CRITICAL BUGS. Also this PPA may overwrite already installed packages you don't want it to!" Apr 12, 2017 at 14:11
