It may be change in the Ubuntu 16.6, when I've created a tutorial about installation on Ubuntu 16.4, after installation everything worked fine, so probably the Ubuntu 16.6 needs additional changes. But that's great that it's working now!

Hi there!
Is there any additional steps for Ubuntu 18.04.1 LTS version?
I have this error when I tried to follow the steps:
A timeout occured after 30000ms selecting a server using CompositeServerSelector
{
Selectors = MongoDB.Driver.MongoClient+AreSessionsSupportedServerSelector,
LatencyLimitingServerSelector{ AllowedLatencyRange = 00:00:00.0150000 }
}.

hey Nguyen,
time out means that server is not reachable.
try these steps.
1-check the connection string
2-make sure that mongo service is running.
3-if you are connecting to external database make sure the external server allows your connection (not blocking port or your ip ..etc)
*NOTICE THAT SERVER NAME AND DB NAME ARE CASE SENSITIVE

Thank you for the reply. I will try

Regards! Could you please tell me the steps to install GrandNode 4:40 in Ubuntu Bionic Beaver no docker with Nginx and Mongo?

Hello,

We are working on the updated installation guide, but you can look at our latest installation guide on Ubuntu - https://grandnode.com/how-to-install-grandnode-on-linux-ubuntu-1604

Best,

Hi, Patryk! I can not get GrandNode 4:40 working on Ubuntu Bionic Beaver (server) with Mongo-Nginx following your latest guide for Ubuntu-1604: although dotnet-sdk-2.2 works correctly (Hello, Word) however it has privilege and patch problems when I run "dotnet restore GrandNode.sln". Could you help me get out of such a frustrating traffic jam?

Can you share with us an error log?

Hi, Patryk. Sorry for the delay in responding, it happens that I survive in a country (Venezuela) where electricity and the Internet are very scarce. But this is what I get when I run "dotnet restore GrandNode.sln":
