That's the funny thing, it says "see log for full details" but there's nothing regarding the packages.

Hey Mike, that sounds very strange. Regarding this

nothing happens when the file gets dragged in the box.

Could you tell me which browser are you using and which package are you trying to install?

This may not be the case but it's worth checking - Can you go to App_Data\packages\installed\ and show me how the installedPackages.config file looks like?

Cheers, Georgs

Hey, I did some more digging into this myself. Here is the log with a possible error.

Creates a Data Type with a Default Value (used for properties that cannot be modified)

This was useful for a project that implements the schema.org types, so each page (article, news, foto) has a default value (Article, newsArticle, Photograph) that may be overridden by another schema.org object type, but if the user does not override anything, the default is used. Therefore, the default cannot be changed.

There can be plenty of other reasons to add a "cannot be modified" property to a document, so the package is now public.]]></readme>

It happens with every package I try to install. We triple checked the permissions already.

Note: I was able to install packages in localhost, there must be a server sides issue?

I have no idea how to install the packages manually by unzipping them so I haven't tried that.

For uninstalling, I have removed the folders and tried again. I could remove all those guid folders in app_data and try again?

Oops, sorry, you don't need to unzip them.

Just unblock the file and select "Install local" in the back office.

Some packages put files in the /bin folder, the /app_data folder, and the /app_plugins folder, and maybe the /Config and /Views folders, and others update the trees.config and the dashboard.config files, and the /app_data/packages/installed/installedPackages.config file.

The installedPackages.config file may actually tell you where everything is after installation.

If you have used the package, you may have files in the /app_data folder that you don't want to lose, so maybe back that one up.

I know you have said this, but you could just check that you have you given the application pool the correct permissions?

Hey,

When I unblock the package and try to install it manually I still get an error.

I'm sitting with someone who has access to the server today to try and fix the problem.

Thanks for trying to help. I think it's just easier to copy the folder form the server, put it on localhost, install the packages and then upload it again. The website is not live yet anyway.

Hey, I actually came across the same issue on another server and another umbraco installation of mine.

I might've came across the problem, does your server have SCOM? A microsoft server monitoring software?

Yeah, we're running it.

Hi,

We had the same issue and after removing SCOM it worked! Thanks a lot!

As we need SCOM for monitoring we found that you can install SCOM manually : https://docs.microsoft.com/en-us/system-center/scom/manage-deploy-windows-agent-manually?view=sc-om-1801

We used the following command:

%WinDir%\System32\msiexec.exe /i path\Directory\MOMAgent.msi /qn USE_SETTINGS_FROM_AD={0|1} USE_MANUALLY_SPECIFIED_SETTINGS={0|1} MANAGEMENT_GROUP=MGname MANAGEMENT_SERVER_DNS=MSname MANAGEMENT_SERVER_AD_NAME =MSname SECURE_PORT=PortNumber ACTIONS_USE_COMPUTER_ACCOUNT={0|1} ACTIONSUSER=UserName ACTIONSDOMAIN=DomainName ACTIONSPASSWORD=Password AcceptEndUserLicenseAgreement=1 NOAPM=1

The NOAPM option installs the Operations Manager agent without .NET Application Performance Monitoring. It seems this this .NET Application Performance Monitoring install something which is not compatible with Umbraco.

Hope this will help somebody,

Let me know what it does if you install it with the workaround! I'm interested to know.

Turns out that you can force the server to use TLS 1.1/1.2 by updating the registry. I used this link as the resource and, once the changes were made and the server was rebooted, I was able to download and install packages from the gallery again.

https://success.outsystems.com/Support/EnterpriseCustomers/MaintenanceandOperations/%28.NET%29EnableSSLProtocolsforyourIntegrations-TLS1.1andTLS_1.2

Hope this helps.

Sean

Instead of editing the registry you can just tell your site to default to TLS 1.2 by either installing - https://our.umbraco.com/packages/developer-tools/codesharetls12umbraco/ or using the code from it

Matt

I did find that plugin but the drawback there is that you have to remember to install it for every Umbraco instance created on the server. We have several instances from v4x to the current version, with new instances being created all the time, and the same developer is not responsible for setting up all of them, so the registry route was better for our setup.
