dotnet-install.sh fails when using "Pair to Mac" in Visual Studio Enterprise 2022

[Mr-Horse]

Describe the bug.

We're trying to connect to a mac to do development on our old "xamarin" project that is now .NET 8.0 iOS. We normally connect to the mac and build/run the app on the mac simulator or iOS device. We've tried a ton of stuff and nothing seems to work. Currently we're unable to develop on the repo because of this issue. We would appreciate any help, thank you.

Reproduction Steps

• Open visual studio solution with iOS project
• Click on the xamarin agent button in the toolbar
• Click add mac button
• Type in the IP address or mac name
• Enter username and password
• 
• Click sign in
• 
• The window shows an error: The dotnet SDK installation '9.0.102-servicing.24611.3' failed. If trying again doesn't work, please refer to the public documentation for more information and troubleshooting: https://aka.ms/pairtomac/dotnet
• Actual error from the script file:
  Xamarin.Messaging.Exceptions.MessagingRemoteException: An error occurred on client IDB17120153 while executing a reply for topic xvs/idb/initialize-dotnet-sdk ---> Xamarin.Messaging.IDB.Contracts.DotNetSdkInstallationException: Could not install dotnet SDK '9.0.102-servicing.24611.3'. Details: /Users/mrhorse/Library/Caches/Xamarin/XMA/SDKs/dotnet/scripts/dotnet-install.sh: line 1440: link_types[$link_index]: unbound variable

What we've tried

• Visual studio and Visual studio code is installed on the PC and Mac(visual studio for mac was deprecated)
• dotnet 8 and 9 Arm64 are installed on the mac from here and here
• Added all required permissions and settings from here
• We've run "dotnet workload restore" on the mac and PC
• We've run "dotnet restore" and "dotnet build" on the Mac, and the solution does build
• We're able to run the script file "./dotnet-install.sh" from the terminal but ONLY with sudo
• cd /users/mrhorse/library/caches/xamarin/xma/sdks/dotnet/scripts
• chmod +x dotnet-install.sh
• sudo ./dotnet-install.sh --version 9.0.102-servicing.24611.3
• dotnet-install: .NET Core SDK with version '9.0.102' is already installed.
• We're able to ssh into the mac from the PC in powershell and run the script file "./dotnet-install.sh" but ONLY with sudo
• We are an admin on the Mac and PC

[Mr-Horse]

Can you attach the content of the dotnet-install scripts packaged by those tools? I suspect that they are using the out-of date versions of those scripts, and you might be impacted by the changes we've been forced to make by dotnet/core#9671.

Here is the content, it won't allow me to add the file, even as a zip:

dotnet-install.sh

``` #!/usr/bin/env bash # Copyright (c) .NET Foundation and contributors. All rights reserved. # Licensed under the MIT license. See LICENSE file in the project root for full license information. #

Stop script on NZEC

set -e

Stop script if unbound variable found (use ${var:-} if intentional)

set -u

By default cmd1 | cmd2 returns exit code of cmd2 regardless of cmd1 success

This is causing it to fail

set -o pipefail

Use in the the functions: eval $invocation

invocation='say_verbose "Calling: ${yellow:-}${FUNCNAME[0]} ${green:-}$*${normal:-}"'

standard output may be used as a return value in the functions

we need a way to write text on the screen in the functions so that

it won't interfere with the return value.

Exposing stream 3 as a pipe to standard output of the script itself

exec 3>&1

Setup some colors to use. These need to work in fairly limited shells, like the Ubuntu Docker container where there are only 8 colors.

See if stdout is a terminal

if [ -t 1 ] && command -v tput > /dev/null; then
# see if it supports colors
ncolors=$(tput colors || echo 0)
if [ -n "$ncolors" ] && [ $ncolors -ge 8 ]; then
bold="$(tput bold || echo)"
normal="$(tput sgr0 || echo)"
black="$(tput setaf 0 || echo)"
red="$(tput setaf 1 || echo)"
green="$(tput setaf 2 || echo)"
yellow="$(tput setaf 3 || echo)"
blue="$(tput setaf 4 || echo)"
magenta="$(tput setaf 5 || echo)"
cyan="$(tput setaf 6 || echo)"
white="$(tput setaf 7 || echo)"
fi
fi

say_warning() {
printf "%b\n" "${yellow:-}dotnet_install: Warning: $1${normal:-}" >&3
}

say_err() {
printf "%b\n" "${red:-}dotnet_install: Error: $1${normal:-}" >&2
}

say() {
# using stream 3 (defined in the beginning) to not interfere with stdout of functions
# which may be used as return value
printf "%b\n" "${cyan:-}dotnet-install:${normal:-} $1" >&3
}

This platform list is finite - if the SDK/Runtime has supported Linux distribution-specific assets,

then and only then should the Linux distribution appear in this list.

Adding a Linux distribution to this list does not imply distribution-specific support.

Here is the content, it won't allow me to add the file, even as a zip:

Thanks, that is the correct script which is puzzling.

Could you try if this fixes your issue?
sudo ./dotnet-install.sh --install-dir /Users/USER/Library/Caches/Xamarin/XMA/SDKs/dotnet --version 9.0.102-servicing.24611.3 --architecture Arm64 --no-path --verbose

The "Pair to Mac" seems to expect the binaries in that directory (based on analogous case here: #407 )

Our script tries to follow 3xx redirects, but it looks like that's failing for your case, and I agree that it looks like your network security is interfering here.

[JanProvaznik]

as a short term fix I would try downloading from https://builds.dotnet.microsoft.com/dotnet/Sdk/9.0.102-servicing.24611.3/dotnet-sdk-9.0.102-osx-arm64.tar.gz and unzipping that to the install-dir manually

preferably convince your network security to not break the link

[baronfel]

@JanProvaznik I think there's a potential bit of hardening we should do on the productversion.txt calls as well - it seems that we're not checking for a real success here (3xx responses don't count as 'failures') and we probably should be. A minimum bar would be failing, but we should probably attempt to follow any redirects to get the final content.

[JanProvaznik]

Also I notice that these don't exist. Shouldn't they @rbhanda ?

[Mr-Horse]

We put in a request to get the domain https://ci.dot.net unblocked. That fixed it. Thanks @baronfel and @JanProvaznik for the help and for being so responsive!

[baronfel]

@Mr-Horse is the builds.dotnet.microsoft.com domain also unblocked? That is the primary domain for stable releases (like the one you're trying to download in your example), and I'd expect it to be preferred over ci.dot.net.

@Mr-Horse is the builds.dotnet.microsoft.com domain also unblocked? That is the primary domain for stable releases (like the one you're trying to download in your example), and I'd expect it to be preferred over ci.dot.net.

That's probably also blocked. I'll have them add that one as well, thanks!

@mmitche should these exist in ci.dot.net?

[mmitche]

No, since this was an internal build. They would exist in internal containers, but not public ones.
