dnn upgrade of 7.0.5 to 7.1.1 install/provider zip files error

Question

I had an error during an in place upgrade of DNN 7. the error occured during the installation of the new providers from the install/providers folder. SPecifically i think it was during the rad editor provider upgrade.

here is the error:

2013-08-27 17:40:54,149 [WS048][Thread:6][FATAL] DotNetNuke.Web.Common.Internal.DotNetNukeHttpApplication - System.Web.HttpUnhandledException (0x80004005): Exception of type 'System.Web.HttpUnhandledException' was thrown. ---> ICSharpCode.SharpZipLib.ZipException: System.ApplicationException: Unknown block type 7 at ICSharpCode.SharpZipLib.Zip.Compression.Inflater.Decode() at ICSharpCode.SharpZipLib.Zip.Compression.Inflater.Inflate(Byte[] buf, System.Web.HttpApplication.CallHandlerExecutionStep.System.Web.HttpApplication.IExecutionStep.Execute() at System.Web.HttpApplication.ExecuteStep(IExecutionStep step, Boolean& completedSynchronously) 2013-08-27 17:42:59,589 [WS048][Thread:6][ERROR] DotNetNuke.Common.Internal.ServicesRoutingManager - Unable to register service routes System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation. ---> System.BadImageFormatException: Could not load file or assembly 'Newtonsoft.Json, Version=4.5.0.0, Culture=neutral, PublicKeyToken=30ad4fe6b2a6aeed' or one of its dependencies.

This makes me think it was a blocked zip file, but I double checked to make sure the zip file was unblocked

Question: Does someone know where this error comes from? Or how can I figure out more specifically where it is comming from

thanks

EDIT #1

So I restored from a backup and tried again, I got the same error but at a different install/provider zip file. I am not sure what is causing this. This error seems to indicate the zip files are corrupted and are not downloaded/uploaded correctly.

EDIT #2

is there a chance that my ftp client is corrupting the zip files during upload? This has been going on for three days with well over a dozen different attempts to upgrade to various versions. I've never had this difficulty with a dnn upgrade ever and I've been using it for years.

Answer 1

It is definitely possible that you're getting corruption issues somewhere.

I would start by downloading the UPGRADE package again, extracting them using 7zip instead of Windows Compression, then try the upload. Maybe try a new FTP client, or see if you can RDP into the machine instead of FTP
