Desktop (please complete the following information):

• OS: MacOS 11.6
• FVM Version: 2.2.4

Additional context

• To attempt to isolate this issue to fvm, I pulled down the latest stable flutter SDK and executed pub get doing ~/path/to/flutter/sdk/bin/flutter pub get on the same project. This completed successfully.
• Additionally, I'm able to curl the URL in the error output just fine:

@btrautmann is this issue happening consistently? I saw another problem but seemed like it was google servers.

[btrautmann]

@leoafarias yeah it's been happening since yesterday (well that's when we noticed it), and another coworker is experiencing the same after doing the above. We have a setup script that installs fvm and we've asked other teammates not to run it in fear of running into this 🙃

[leoafarias]

I saw another issue this morning when pulling google data but seems like it was a flutter backend hick up.

Is the problem still happening for you? Fvm just proxies the commands so not sure if it's fvm related.

[btrautmann]

Yeah, I've been testing this all morning. I just tried moments ago with the same failure. flutter pub get in the standalone SDK completes without issue.

[btrautmann]

I figured I'd open this just in case something came to your mind, but if you're pretty confident it isn't fvm I have no problem closing this to debug further.

[leoafarias]

I suggest removing the cached version in fvm and installing it again.

Maybe during the install the error happened and something got corrupted.

Will look out for it though. Thanks.

[btrautmann]

I've tried completely getting rid of fvm via brew uninstall fvm and reinstalling, as well as installing it via dart pub global activate fvm and both have the same issue. I just now figured I should try doing a flutter create my-app in a different directory in case something about our project was the issue, but that also failed.

[leoafarias]

@btrautmann what I mentioned was the actual cached version of 2.5.3 cached by fvm and running again.

I will be on the lookout if there are any issues.

[btrautmann]

the actual cached version of 2.5.3 cached by fvm and running again.

@leoafarias where would that be?

[leoafarias]

If you installed stable fvm remove stable or if it was 2.5.3 directly just do fvm remove 2.5.3, and install it again with fvm install 2.5.3

[btrautmann]

🤔 Is this expected?

flutter [main] % fvm remove 2.5.3                 
Building flutter tool...
2.5.3 is current configured as "global". Do you still would like to remove? Y/n: Y
Removing 2.5.3...
2.5.3 removed.
flutter [main] % fvm install 2.5.3
/Users/brandontrautmann/.pub-cache/bin/fvm: line 8: dart: command not found

flutter [main] % fvm install 2.5.3
/Users/brandontrautmann/.pub-cache/bin/fvm: line 8: dart: command not found

No idea what is going on here... this seems very weird, can I take a look at this setup script that you are running to install fvm

[leoafarias]

I believe this is related to the issue you are seeing here #352

I am curious to see the Dart path configuration also, is that an alias?

[btrautmann]

FLUTTER_VERSION=2.5.3
COCOAPODS_VERSION=1.10.0

install_flutter() {
  set -e
  # we used to rely on a globally installed dart from homebrew in order to access fvm
  brew uninstall --force dart || true

  append_to_rcfile 'export PATH="$PATH:$HOME/fvm/default/bin"'
  export PATH="$PATH:$HOME/fvm/default/bin"

  # make sure that your shell can find global dart cli commands
  append_to_rcfile 'export PATH="$PATH:$HOME/.pub-cache/bin"'

  fvm install "$FLUTTER_VERSION"
  fvm global "$FLUTTER_VERSION"

  flutter config --enable-macos-desktop

  flutter doctor
  flutter precache --force --ios --android --macos
}

This is the interesting bit ☝️

[leoafarias]

Oh ok.. so that makes sense the warning was correct. The global configured version was the one running the command that is why you had the command not found after.

Not 100% sure what is happening here but looking through your initial error, it did say that there might be an issue with your connection, and I believe was probably more visible because of the precache.

I think that during the initial install something went corrupt because of the connection. So when you were running the global you were having issues.

[btrautmann]

After chatting with a teammate, we are thinking this is likely related to an internal issue with our certs, and I'm going to close this until we discover otherwise.

[kuyazee]

@btrautmann how do you run the append_to_rcfile when I run it, it just says command not found: append_to_rcfile for me

[btrautmann]

@btrautmann how do you run the append_to_rcfile when I run it, it just says command not found: append_to_rcfile for me

Ah, sorry, that's just an internal helper that appends the content to the correct rc (bashrc or zshrc) file if not already present.

We've actually come to the conclusion that there's something going on with the flutter install itself, as installing via Github as detailed here fails for the same people. We've opened flutter/flutter#93739 as a result.
