Can you run an strace and upload the log file (logfile below) somewhere?
strace -f -o logfile dotnet new console -o hwapp
Edit: does dotnet --info work?
Here you go :
$ dotnet --info

Hi, any news on this ? Anything else I can do to help debug?
@livarcocc is this the one people have been working around by disabling the first run experience?
export DOTNET_CLI_TELEMETRY_OPTOUT=1
removed the segmentation fault for me

should I close the issue or you want it left open until a real fix has been issued?
Lets leave it open until @livarcocc confirms that there is an issue somewhere tracking the fix. Once we have that, this can be closed. Thanks @ierpe!
@Petermarcu @steveharter can you help debug this and understand why the telemetry code is causing a seg fault? If this were in native code, I would expect a stack trace somewhere. But we will investigate.
@livarcocc I’m installing fresh debian now, will report back tomorrow.
I couldn’t repro. I used debian stretch. One difference is that dotnet --info reports the RID as Linux-x64 instead of debian-x64.
dotnet --info

@ierpe what is the contents of your /etc/apt/sources.list.d/dotnetdev.list file? I have:
deb [arch=amd64] https://packages.microsoft.com/repos/microsoft-debian-stretch-prod stretch main
the same issue @Mac
the official guide says:
dotnet new console -o hwapp
cd hwapp
I checked the dotnet help (dotnet core sdk 2.0)

all the guide shuold be update to :

cd hwapp
dotnet new -t console
FWIW here’s my Debian Stretch environment (no repro, clean install)

@icedfish
the same issue @mac
So you’re also getting the seg fault during dotnet new console?
Does export DOTNET_CLI_TELEMETRY_OPTOUT=1 prevent the seg fault?
@ierpe have you tried to debug the seg fault, or look at any dumps in order to determine the crashing modulestack? I can send you gdb instructions.
@icedfish
I checked the dotnet help (dotnet core sdk 2.0)
Can you confirm this? What does dotnet --version say? What does dotnet --info say?
~ dotnet help new .NET Initializer Usage: dotnet new [options] Options: -h|--help Show help information -l|--lang <LANGUAGE> Language of project [C#|F#] -t|--type <TYPE> Type of project ➜ source mkdir dotnet
That looks like the older 1.0 Preview SDK. -t does not work with the 1.x or 2.x SDKs.
@ierpe probably the easiest way is to catch the seg fault with gdb if you can. You’ll likely need to be root to install that. So
su
apt-get install gdb
exit
and then run dotnet:
gdb --args dotnet new console
run
after seg fault
hopefully you get a crashing module (libcurl?) and stack.
@omajid sorry , I checked my system, find that I used to install the old 1.0RC SDK before install the new 2.0 sdk.
after uninstall the old version by the cli script
and reinstalled the sdk 2.0, It’s ok now.
But it’s really puzzle, the the 2.0 sdk not remove the old sdk automaticlly or even notify me the incompact…..
@steveharter is that what you wanted ?

@ierpe yes thanks. It is likely crashing when calling into OpenSsl.
Can you run a couple commands please:
$ openssl version
and
ls /usr/lib/x86_64-linux-gnu/libssl.so.*
You should get back
OpenSSL 1.1.0f 25 May 2017
and
/usr/lib/x86_64-linux-gnu/libssl.so.1.0.2 /usr/lib/x86_64-linux-gnu/libssl.so.1.1
If not, and you’re getting the 1.0.0 version you can give this a try:
apt-get remove ssl1.0.0
apt-get install ssl1.0.2
@steveharter
$ openssl version
OpenSSL 1.1.0f 25 May 2017
$ ls /usr/lib/x86_64-linux-gnu/libssl.so.*
/usr/lib/x86_64-linux-gnu/libssl.so.1.0.0
/usr/lib/x86_64-linux-gnu/libssl.so.1.0.2
/usr/lib/x86_64-linux-gnu/libssl.so.1.1
@ierpe since you have the 1.0.0 version, that is likely conflicting and has been a problem for others. You can remove that by doing an apt-get remove ssl1.0.0
Typically the 1.0.0 version is there due to an upgrade to stretch or buster, and not a clean install. It could have come from another app’s dependency as well.
cc @bartonjs is there an issue to address this in some manner? Like if 1.0.2 is there use that first. Thanks
@steveharter removing ssl1.0.0 fixed it for me, thanks for the support!
@steveharter The reason I had 1.0.0 version was that spotify-client depends on it and I had manually installed it. Please refer to my post in #649
This was referenced
May 17, 2018
I have multiple apps that depend on version 1.0.0 and others that depend on 1.0.2.
What do I do?
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 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

Earlier this evening I installed .NET core preview 2 on Debian Sid, and tried to create a new project via the dotnet new command, only to get a segmention fault error message:
matt@IDSiG:~/git/testproject$ dotnet new console Segmentation fault
In this instance, the segmentation fault on creation of a new project was is due to .NET Core telemetry being incompatible with version 1.1 of OpenSSL.
A quick check via dpkg shows the current version I have of the OpenSSL package is indeed 1.1
