When I try to run ‘dotnet new console’ in either the Ubuntu or VS Code Terminal, I get the following error

Segmentation fault (core dumped)

Running it in the Ubuntu Terminal seems to give more information, looks like it’s failing to do the ‘dotnet restore’ that automatically runs when you do ‘dotnet new console’

Getting ready...
The template "Console Application" was created successfully.

Running 'dotnet restore' on /home/max/Programming/C Sharp/Hello World/Hello World.csproj...

Restore failed.
Post action failed.
Description: Restore NuGet packages required by this project.
Manual instructions: Run 'dotnet restore'

Segmentation fault (core dumped)

Running dotnet restore manually just gives the segfault error

Version of Ubuntu is 21.04, I have already installed everything as per https://learn.microsoft.com/en-us/dotnet/core/install/linux-ubuntu#2104-

Another thing to note is that I can build and run C Sharp applications fine in Monodevelop, and I can run non .NET languages such as Python fine in VS Code

Any ideas / assistance would be appreciated, thanks

I’m seeing a similar issue. I have a .NET tool Neo.Express that has a dependency on native RocksDB library. Native dependencies installed via APT.

Using a fresh Ubuntu 20.04 VM + .NET 6 installed via SNAP, I can execute the neo express create command (which uses only managed code) but the if I execute the run command (which loads the rocksdb native library) I get seg fault.

Doing the exact same thing with .NET 6 installed via APT works fine.

Note, I can run dotnet new console --framework net6.0 and dotnet complete "dotnet a" on this VM w/o a seg fault

(Update): I’m guessing this is a different issue than what @arylee reported. I tried running under a native debugger and it is crashing when it goes to open the rocksdb .so that is included in my tool package. But I don’t understand why it seg faults instead of throwing a load exception. If you try to run this command on Ubuntu when dotnet is APT installed, I get a type load exception instead of a seg fault. I don’t understand SNAP vs APT installation well enough to understand the behavior difference.
