    Issue with uninstalling packages after upgrade to 7.5.3

    Hello,

    We have got an issue with uninstalling packages after upgrade to 7.5.3. As soon as we click on any package under 'Installed packages' node, we get the following error:

    2016-10-12 14:32:38,086 [P5208/D20/T500] ERROR Umbraco.Core.UmbracoApplicationBase - An unhandled exception occurred System.Web.HttpUnhandledException (0x80004005): Exception of type 'System.Web.HttpUnhandledException' was thrown. ---> System.NullReferenceException: Object reference not set to an instance of an object. at umbraco.cms.businesslogic.packager.data.Save(PackageInstance package, String dataSource) at umbraco.cms.businesslogic.packager.InstalledPackage.Save() at umbraco.presentation.developer.packages.installedPackage.Page_Load(Object sender, EventArgs e) at System.Web.UI.Control.OnLoad(EventArgs e)

    What can we do to resolve this annoying problem?

    Thanks in advance, Alexander

    Hi Alexander,

    What package did you install ?

    Is this package compartible with your version of Umbraco?

    Thanks,

    Alex

    Hi Alex,

    We didn't install any packages after the upgrade (from 7.4.something btw).

    Currently we have got the following packages:

    • Cultiv Search Engine Sitemap
    • Optimus.Core + Less and Sass providers
    • Robots.txt Editor
    • uBlogsy
    • UmbBackofficeMembershipProvider
    • uSync.Backoffice

    Is there a way to know what package causes the issue?

    And what package do you want to uninstall?

    Actually, we don't want to uninstall anything, but we also don't expect to see crashes of the system, so I prefer to solve the issue for future.

    Clicking on any of those packages brings that problem.

    I have the exact same problem, after upgrading from 7.4.3 to 7.5.3, on clicking any package it gives object reference not set to an instance of an object.

    [NullReferenceException: Object reference not set to an instance of an object.] umbraco.cms.businesslogic.packager.data.Save(PackageInstance package, String dataSource) +469 umbraco.cms.businesslogic.packager.InstalledPackage.Save() +52 umbraco.presentation.developer.packages.installedPackage.Page_Load(Object sender, EventArgs e) +3230 System.Web.Util.CalliEventHandlerDelegateProxy.Callback(Object sender, EventArgs e) +51 System.Web.UI.Control.OnLoad(EventArgs e) +92 umbraco.BasePages.BasePage.OnLoad(EventArgs e) +14 System.Web.UI.Control.LoadRecursive() +54 System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint) +772

    Sort of the same problem here.

    I just only get the NullReferenceException error when i actually try to uninstall a package.

    Anyone found a solution?
