Before creating a bug report please make check the following

• [X] You have read our FAQ

Additional context running in docker as root

[vbrandl]

I have the same problem using podman and running as non-root (inside the container/build process, I am root, but I run docker build as non-root user). When building my dockerfile, I get the described permission errors. Running the build as root works, but I'd prefer building using a non-root user...

Were you able to fix this?

[mcmah309]

I have the same issue as well. Running as root does not fix it for me.

[RodrigoDornelles]

@vbrandl @mcmah309 I have an opensource docker image that works around this problem.

• rodrigodornelles/sdkman

https://github.com/RodrigoDornelles/docker-images/blob/db6f47bde097cf55a0ad87bf5de4bac715ea2147/sdkman/docker-entrypoint.sh#L13

how to use:

podman run --rm -v /tmp:/tmp -v $(pwd):/app -w /app rodrigodornelles/sdkman:latest
sdk install java 17.0.9-oracle
fei 3.13.9
flutter pub get
flutter build apk

[mcmah309]

You're the man! :raised_hands:

I pulled your solution out into a script that works on my container instance

#!/bin/bash
# `./fvm_tar_workaround.sh on`  # To install the custom tar
# `./fvm_tar_workaround.sh off` # To remove the custom tar
set -euo pipefail

install_custom_tar() {
  # Create the custom tar script with the flag as default
  echo -e "#!/bin/bash\nset -e\n/bin/tar \"\$@\" --no-same-owner" > /tmp/tar
  chmod +x /tmp/tar
  if [ ! -d /usr/local/bin ]; then
    mkdir -p /usr/local/bin
  fi
  mv /tmp/tar /usr/local/bin/tar
  if ! echo "$PATH" | grep -q "/usr/local/bin"; then
    echo 'export PATH="/usr/local/bin:$PATH"' >> ~/.bashrc
    source ~/.bashrc
  fi
  if which tar | grep -q "/usr/local/bin/tar"; then
    echo "Custom tar command installed successfully."
  else
    echo "Failed to install the custom tar command."
  fi
}

uninstall_custom_tar() {
  if [ -f /usr/local/bin/tar ]; then
    rm /usr/local/bin/tar
    echo "Custom tar command removed successfully."
  else
    echo "Custom tar command is not installed."
  fi
}

if [ "$1" == "on" ]; then
  install_custom_tar
elif [ "$1" == "off" ]; then
  uninstall_custom_tar
else
  echo "Usage: $0 {on|off}"
  exit 1
fi

I'm not familiar with the fvm implementation, so not sure what needs to get done on that side to fix this bug
