I've build a Hyperledger Fabric network (v2.0.0) and I want to know if Hyperledger Explorer tool is compatible with this version of network.
Can anyone help me?
As of now regarding Hyperledger, Hyperledger Explorer can support up to Hyperledger Fabric 1.4.8
Ref:- https://github.com/hyperledger/blockchain-explorer#10-release-notes----
You are in luck. As of July 1st 2020 they support v2.0 and above.
Just download the latest docker image build of version: v1.1.1 (Jul 17, 2020) and you are good to go.

Currently I am using Ubuntu 22.04 LTS version on Oracle virtual machine. When I try to install all the prerequisite of hyperledger composer it's showing an error Ubuntu jammy is not supported.
I am unable to run ./prereqs.sh command. Please help me
Unfortunately Hyperledger Composer has been unmaintained since August 2019 so I'm not surprised that you have hit problems with prereqs.
I would strongly recommend using Hyperledger Fabric directly, which is what Composer was based on. Although it is still not as straightforward as Composer, there have been quite a few improvements to Fabric over the last few years which should hopefully make getting started a bit easier. For example, have a look at the full-stack-asset-transfer-guide repository, which was used in a workshop at the Hyperledger Global Forum last week.
I would like to know what is the recommended version of Hyperledger Fabric (1.4 or 2.x) or if it is 100% recommended to implement the most recent version, in this case 2.x.
This is because for obvious reasons 1.4 has more downloads and implementations for having more time published.
Greetings and thanks
Hyperledger fabric 1.4 community support will finish in April 2021 (Service providers may provide support for longer). The recommendation is that you should start with Hyperledger fabric 2.2 which is the current LTS version or 2.3 if you want to try some of the newer capabilities
I wanna build a blockchain on hyperledger fabric. So I found some good repos in version 1 but not in hyperledger fabric version 2.
Would you recommend to use the old version instead of the latest version (2.0)?
Thanks for any recommendation/suggestion.
Hyperledger Fabric 2.2 LTS was released July 2020, this means that Hyperledger Fabric 1.4 LTS will go out of support in April 2021 (ie do not expect any updates or releases to the 1.4 version such as bug/security fixes).
Any new project should start with the latest LTS version which is currently 2.2
Where can I find a specific version of Service FabriŃ, I need 5.6 runtime and 2.6 sdk version. Is there any download list for Service Fabric versions?
I found the link https://blogs.msdn.microsoft.com/azureservicefabric/2017/06/20/release-of-sdk-2-6-220-and-runtime-5-6-220-refresh-for-windows , but there no link for downloading this version. Every link leads to the latest version.
I found it!
https://servicefabricsdkstorage.blob.core.windows.net/public-release-notes/Microsoft%20Azure%20Service%20Fabric%20Release%20Notes%20-%20SDK%202.6.220%20-%20Runtime%205.6.220.docx
Here is a link where the downloading links of service fabric Runtime, SDK and VS Tools can be found.
So the algorithm for seeking download links:
Find the release update on Azure
site.(https://blogs.msdn.microsoft.com/azureservicefabric/2017/06/20/release-of-sdk-2-6-220-and-runtime-5-6-220-refresh-for-windows/
in my case)
Find release notes of a specific release.
Download Release Notes
Find Download links at the end of a document.
Can use Web Platform Installer to install different versions of Service Fabric SDK together with runtime. If you don't want to install the corresponding SDK, only runtime, actually you can go to Web Platform Installer's folder to find the package, such as "%LOCALAPPDATA%\Microsoft\Web Platform Installer\installers\ServiceFabricRuntime_6_5_CU5".
When I'm deploying the Service Fabric Application with new version, the complete application is getting replaced with new version in service fabric cluster. And it is working fine as expected in upgrade scenario. But, When I deploy the application with downgraded version, application is not getting replaced rather it is again creating an application with older version.
After the application deployment, I have two different versions of same application in service fabric cluster.
How we can downgrade the application to older version with application deployment. Does we need to change settings/parameters for cluster or in power shell command.
Service Fabric cluster with two versions after deployment of older version image
Thanks.
This is a view of the Service Fabric Image store, which shows the current versions available, below this you should be able to see the actual version that is being used within the cluster, see below, versions 1.0.0 and 1.0.1 are currently in the image store but version 1.0.0 is the version being used.
You can confirm this by looking at your nodes as well.
EDIT:
To remove the unwanted versions from the cluster run the following in PowerShell, obvious replace with your application name and version.
> Unregister-ServiceFabricApplicationType -ApplicationTypeName DowngradeDemoType -ApplicationTypeVersion 1.0.1
