When " flutter upgrade", I get "Permission denied" error

I would like to build a web application with Flutter. I followed this instruction. https://flutter.dev/docs/get-started/web I use Windows 10, Windows Subsystems for Linux, Debian 10.

I installed Flutter SDK in ~/development/ directory and have already set the path.

I input this.

flutter channel beta

And get this result.

To ensure that you're on the latest build from this channel, run 'flutter
upgrade'

Next, I input this.

flutter upgrade

Then, I get this.

Downloading Dart SDK from Flutter engine ef9215ceb2884ddf520d321bcd822d1461330876...
mv: cannot move '/home/kazu/development/flutter/bin/cache/dart-sdk' to
'/home/kazu/development/flutter/bin/cache/dart-sdk.old': Permission denied

So, I read this NOTE. https://flutter.dev/docs/get-started/web#set-up

The flutter upgrade command silently fails when origin points to a personal fork. 
To validate that origin points to https://github.com/flutter/flutter.git, 
run the following commands in the root directory of your local copy of the 
https://github.com/flutter/flutter repository:

Then, I input this.

cd ~/development/flutter/
git remote get-url origin

Then my terminal returned this.

https://github.com/flutter/flutter.git

So, I tried again.

flutter upgrade

I got the same result.

Next, I tried sudo

sudo flutter upgrade

Then I got this.

sudo: flutter: command not found

Could you give me any advice please?

Solution

  • For me, The problem you got is the current user not have permission in dart-sdk folder. You need to re-check the permission or dart-sdk folder.

    Example run ls -la to see the details

    drwxr-xr-x 10 user-xxx staff 320 6 Jun 10:18 dart-sdk

    If not current user, using sudo chown to change owner of dart-sdk folder.

    try flutter upgrade again.
