I installed dotnet SDK 6.0 with apt followed by the document. It works! But the snap way fails.

devhawk · 2022-04-11T16:56:18Z

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.

devhawk · 2022-04-11T23:07:26Z

I created a simple console app via dotnet new on my SNAP based VM. I can run the app from the command line, but if I open up VSCode on the folder I get a warning that the .NET Core SDK cannot be located and OmniSharp can't load this very simple one line project w/o zero additional dependencies. But if I open the terminal inside VSCode, I can dotnet run the app and get "Hello, World!" as the output

devhawk · 2022-04-11T23:21:22Z

Looks like this is a known issue that isn't going to get fixed

PhilParisot · 2022-04-15T06:15:37Z

Same issue on Ubuntu 21.10 install

PhilParisot · 2022-04-15T17:33:44Z

Just checked, the Snap installs and runs fine on Ubuntu 20.04 for some reason.

wcdeich4 · 2022-06-16T14:10:20Z

7.0.100-preview.5.22307.18 worked for me in Ubuntu 22.04 LTS

njavilas2015 · 2022-08-28T03:19:01Z

the commando is => sudo snap refresh dotnet-sdk --beta

njavilas2015 · 2022-08-28T03:30:03Z

good evening I'm trying to start a good new project and I can't get it, a hand would be very useful to me I'm just starting

danmoseley · 2022-08-28T17:26:01Z

@njavilas2015 What is your distro and version?
Can you run under gdb or lldb and get a backtrace?

njavilas2015 · 2022-08-28T19:10:39Z

I have made the installation from the page as it appears

I have fixed it by just installing apt install dotnet

thatguywiththefunnyname · 2022-10-25T09:18:51Z

Don't know if this is any helpful at all, however on POP 22.04 I checked apt to see if it has any dotnet packages and found that it had the dotnet-sdk-6.0 so it ran
sudo apt install dotnet-sdk-6.0 and it seemed to work fine.

Hope it helps :)

zamis · 2022-11-11T12:10:01Z

Some observations on this error in the blog https://www.hanselman.com/blog/13-hours-debugging-a-segmentation-fault-in-net-core-on-raspberry-pi-and-the-solution- was
you can compare apt-get and snap install binaries
I think there will be gaps

Works for me as well, thanks!

has same issue from time to time on different Ubuntu 20.04 VPSs
not obvious at all what causing it, there is no clear information where is the core dumped and how to find out the root of issue

See dotnet/runtime#67465

please fix. dotnet new console. segmentation fault (core dumped)

@goff73 please share version used, distro version, how you acquired dotnet, and if possible the stack trace.

goff73 · 2023-01-14T21:37:28Z

I think I was using it through snap. I just got it to work when reinstalling with the scripted install. https://learn.microsoft.com/en-us/dotnet/core/install/linux-scripted-manual#scripted-install Thank you. No more errors. (Linux ubuntu with .net 7.)

orion6dev · 2023-03-17T12:34:01Z

Same issue here. After removing the SNAP install and re-installing using APT instructions here, it worked.
