It works. Thanks

This didn't work for me unfortunately, seems strange for us to get this after Umbraco upgrade....

I can't upgrade Umbraco or Umbraco Forms whilst I get this message

Hi Alex,

It was a problem Newtonsoft and System.Threading.Tasks.Dataflow. Once I removed those from packages.config it worked. However I'm not not able to upgrade to 7.6.1 because I get the following in VS!

Unable to find a version of 'UmbracoCms.Core' that is compatible with 'Archetype.Binaries 1.13.2 constraint: UmbracoCms.Core (≥ 7.2.2)', 'Codery.TextCount 1.0.8 constraint: UmbracoCms.Core (≥ 7.5.6)', 'Our.Umbraco.CoreValueConverters 3.1.2 constraint: UmbracoCms.Core (≥ 7.4.2 && ≤ 7.6.0)', 'Our.Umbraco.NestedContent 0.4.0 constraint: UmbracoCms.Core (≥ 7.1.4)', 'RJP.UmbracoMultiUrlPicker 2.0.0 constraint: UmbracoCms.Core (≥ 7.6.0 && < 8.0.0)', 'Terratype 1.0.8 constraint: UmbracoCms.Core (≥ 7.0.0)', 'UmbracoCms 7.6.1 constraint: UmbracoCms.Core (= 7.6.1)', 'UmbracoForms.Core 6.0.1 constraint: UmbracoCms.Core (≥ 7.6.0 && < 7.7.0)', 'uSync.Core 5.6.3.740 constraint: UmbracoCms.Core (≥ 7.4.0)'

Looks like it was Umbraco Core Property Value Converters that was holding it back. I removed that and it worked. I presume its because this is now in the core.....

Yes, it's in Core, what if you disable it?

I needed to remove the package from my project for Umbraco to upgrade

Oh yeah i've removed mine after the upgrade too

Hi Guys,

I am experiencing a related issue when trying to update Umbraco to 7.6.4

Just Simply trying to update UmbracoCMS via nuget and is not allowing me because of this error.

An error occurred while retrieving package metadata for 'Newtonsoft.Json.10.0.2'

I tried to follow the above steps to solve this problem.. but first of all, I do not have any corrupted files in the packages.config.. and I also I tried to remove the mentioned packages that Ben mentioned and again, no success.

I would appreciate a lot any kind of help / suggestments how I can actually update my Umbraco without these issues.

Thank you.

Hi Simon

Can you show what do you have in web.config, assemblyBinding section?

Thanks,

Alex
