How to install gcsfuse on Ubuntu in 15 seconds

export GCSFUSE_REPO=gcsfuse-`lsb_release -c -s`
echo "deb http://packages.cloud.google.com/apt $GCSFUSE_REPO main" | sudo tee /etc/apt/sources.list.d/gcsfuse.list
curl https://packages.cloud.google.com/apt/doc/apt-key.gpg | sudo apt-key add -
sudo apt-get update
sudo apt-get install gcsfuse

If that doesn’t work (such as for Ubuntu 21.10 impish at the time of writing this post), use the following method:

curl -L -O https://github.com/GoogleCloudPlatform/gcsfuse/releases/download/v0.39.2/gcsfuse_0.39.2_amd64.deb
sudo dpkg --install gcsfuse_0.39.2_amd64.deb
rm gcsfuse_0.39.2_amd64.deb

This is a summary from the official docs.
