WSL: running/installing flutter from master fails.

[JordanMajd]

Using WSL on Windows 10 I am unable to run/install flutter via the master channel; whereas I have no issues with the latest stable release. Running any flutter command from master fails with:

Building flutter tool...
Connection closed while receiving data
Error: Unable to 'pub upgrade' flutter tool. Retrying in five seconds... (9 tries left)

I've reviewed similar issues, however none produced satisfactory results. I tried reproducing the issue directly on an Ubuntu server and everything ran fine; it would seem it is a WSL related issue.

System Information

System information:

• Windows 10 Pro 1809 17763.737
• Linux <Hostname> 4.4.0-17763-Microsoft #379-Microsoft Wed Mar 06 19:16:00 PST 2019 x86_64 x86_64 x86_64 GNU/Linux

Steps to Reproduce

Before either I ensured I had prerequisites installed and my system fully upgraded:

sudo apt update
sudo apt upgrade
sudo apt install curl git unzip xz-utils libglu1-mesa curl

Method One: SDK Install

wget https://storage.googleapis.com/flutter_infra/releases/stable/linux/flutter_linux_v1.9.1+hotfix.4-stable.tar.xz
tar xvf flutter_linux_v1.9.1+hotfix.4-stable.tar.xz

# flutter commands work now
./flutter/bin/flutter config --no-analytics # this should be the default setting btw
./flutter/bin/flutter --version

# lets switch over to master
./flutter/bin/flutter channel master

# fails
./flutter/bin/flutter upgrade

# any flutter command will now fail since  switching to master channel
./flutter/bin/flutter --version # fails
./flutter/bin/flutter doctor # fails

Method Two: Git Install

git clone -b master https://github.com/flutter/flutter.git

# any flutter command will now fail:
./flutter/bin/flutter --version
./flutter/bin/flutter upgrade
./flutter/bin/flutter doctor

Same problem on MacOS Mojave 10.14.6

[kevin-sakemaer]

It also fail if you do this :

$ git clone -b stable git@github.com:flutter/flutter.git
$ flutter --version
Building flutter tool
Connection closed while receiving data
Error: Unable to 'pub upgrade' flutter tool. Retrying in five seconds... (9 tries left)
...

so it's not only on master.

[silvanocerza]

I had the same problem on WSL, solved by adding /usr/lib/dart/bin to PATH. Might not be the same problem though.

[pothos-dev]

I got the same problem (WSL2 on Windows 10), adding dart to PATH did not help.

[LuckierDodge]

Also seeing this issue (WSL1 on W10).

[ilyoungkim]

Not working flutter(WSL1 on W10).

I have same issue with @ilyoungkim .

[coolbeatz71]

Hey, @ilyoungkim @CXZ7720 I had the same problem too, It happens because you probably installed a windows copy of flutter but trying to run it inside WSL which a Linux environment. You should consider installing the Linux copy too

[CXZ7720]

Hello, @coolbeatz71.
I didn't installed windows copy of flutter.
I just installed new build of flutter_linux_1.17.1-stable.tar.xz.

Here's full copy of WSL console.
Sadly until now, it just print out errors.

It says you are running flutter from /mnt/c/src/flutter/bin.
Can you provide the echo $PATH output from wsl?
You can try the following workaround: microsoft/WSL#1493 (comment)

Oh, I See. Thanks for your comment.
I realized that there are mixed value of windows and linux value at $PATH.
I followed instruction of the comment. microsoft/WSL#1493 (comment)

After I changed my registry value from 7 to 5, echo $PATH output shows only Linux values.

kygha7205@DESKTOP-1T1AT4I:~$ echo $PATH
/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/snap/bin:/home/kygha7205/flutter/bin

But, unfortunately, every flutter command doesn't work. It only prints like this.

kygha7205@DESKTOP-1T1AT4I:~$ flutter --version
Unhandled exception:
OS Error: Connection refused, errno = 111
kygha7205@DESKTOP-1T1AT4I:~$ flutter doctor -v
Unhandled exception:
OS Error: Connection refused, errno = 111

In this case, I think WSL found right linux binaries, but there are some OS specific problems.
