If you try to install gcsfuse on Ubuntu 22.04, you will face two issues. First, the signature can’t be verified due to the new method of managing APT keys. Secondly, the gcsfuse repo does not have packages for Ubuntu 22.04 even 5 months after its release:
Err:10 http://packages.cloud.google.com/apt gcsfuse-jammy Release 404 Not Found [IP: 64.233.161.101 80]
You can work around both issues by force-installing the bionic packages which appear to work fine for me.
export GCSFUSE_REPO=gcsfuse-bionic echo "deb [signed-by=/usr/share/keyrings/gcsfuse.gpg] http://packages.cloud.google.com/apt $GCSFUSE_REPO main" | sudo tee /etc/apt/sources.list.d/gcsfuse.list wget -qO- https://packages.cloud.google.com/apt/doc/apt-key.gpg | sudo gpg --dearmor --yes --output /usr/share/keyrings/gcsfuse.gpg
