The elementaryOS team has shipped an urgent fix for a critical bug that causes AppCentre crash. The issue was preventing updates in AppCentre from showing contents. Since the issue had reported, elementaryOS team was working closely to find the origin of issue and they have succeeded in their attempt.
It was figured out that, actual issue was rooting down to PackageKit, under the hood service of AppCenter for retrieving list of software packages and available updates. There was some deprecated piece of code named get-distro-upgrades in PackageKit maintained in elementary repositories. Though this code was patched, there were some hidden references to it and it was triggered following the release of base project, ie, Ubuntu 17.04. It was getting hanged while fetching update information and was preventing proper functioning of AppCenter. After figuring out this issue, elementary team has created a patch to resolve the issue and it is shipped as an update.
Usually, elementaryOS team encourages updating software through AppCentre. But, this time there is no way other than falling back to command prompt as AppCentre updates are not working. elementaryOS users can get the fix using the sudo apt update & sudo apt upgrade commands.
