[mrparadox213]

Problem encountered on https://dotnet.microsoft.com/en-us/learn/dotnet/hello-world-tutorial/install
Operating System: linux (Linux mint 20.2)

I generated a ASP.NET project template but when i cd into the directory and run sudo dotnet watch i get the following error code
I Installed the dotnet SDK using snap

watch : Exited with error code 139
watch : Waiting for a file to change before restarting dotnet...

Hello @mrparadox213. I'm unable to reproduce this issue in my environment. Error code 139 might indicate something is amiss with permissions, and I generally have not needed to use sudo for running dotnet.

Can you confirm that you followed all the setup steps for installing .NET with Snap?
https://docs.microsoft.com/en-us/dotnet/core/install/linux-snap

If so, we'll need more information on how to reproduce this. Was everything successful as expected leading up to running dotnet watch?

Hi thanks for your reply @jeffhandley i did follow the steps ts install dotnet SDK and using sudo is a must because when running dotnet it reply with a permission denied error message

cannot snap-exec: cannot exec "/snap/dotnet-sdk/152/snap/command-chain/snapcraft-runner": permission denied

Thanks for the confirmation, @mrparadox213. I'm going to transfer this issue to the dotnet/sdk repository for further triage/investigation by that team.

FIX:

Probably, you can update documentation, to add export PATH to .bashrc, as well, otherwise it is good

~/.bashrc

# dotnet
export DOTNET_ROOT=/snap/dotnet-sdk/current
export PATH=$DOTNET_ROOT:$PATH

# bash parameter completion for the dotnet CLI

_dotnet_bash_complete()
{
  local word=${COMP_WORDS[COMP_CWORD]}

  local completions
  completions="$(dotnet complete --position "${COMP_POINT}" "${COMP_LINE}" 2>/dev/null)"
  if [ $? -ne 0 ]; then
    completions=""
  fi

  COMPREPLY=( $(compgen -W "$completions" -- "$word") )
}

I have a solution for the sudo-ers in snap package users:

1. Add export PATH to ~/.bashrc

export DOTNET_ROOT=/snap/dotnet-sdk/current
export PATH=$DOTNET_ROOT:$PATH

2. Add dotnet group and add it to sudo-ers

sudo groupadd dotnet
sudo usermod -aG dotnet $USER

Logoff and login to reapply rules

newgrp dotnet

@marcpopMSFT this issue is not specific to dotnet-watch. @funcelot points out that the documentation for installs via SNAP might be missing some steps:

Probably, you can update documentation, to add export PATH to .bashrc, as well, otherwise it is good

Presumably it's this page - https://docs.microsoft.com/en-us/dotnet/core/install/linux-snap. Do you know who the best person to follow on this might be?

@dleeapho who's our best contact for snaps?
