gcsfuse failing to install on centos-7

Question

Since Thursday 1st of April we have an issue on a GCP comoute VM which is launched from a base centos-7 image daily.

When launch the startup script will install gcsFuse using the commands listed here: https://github.com/GoogleCloudPlatform/gcsfuse/blob/master/docs/installing.md#centos-and-red-hat-latest-releases

This installation method is now failing since the latest release:

Does anyone know how to resolve this error?

Answer 1

There's a quick workaround but that means skipping GPG repo key verification. I just changed repo_gpgcheck=1 to repo_gpgcheck=0 and left the rest as it is.

Final script would look like:

sudo tee /etc/yum.repos.d/gcsfuse.repo > /dev/null <<EOF
[gcsfuse]
name=gcsfuse (packages.cloud.google.com)
baseurl=https://packages.cloud.google.com/yum/repos/gcsfuse-el7-x86_64
enabled=1
gpgcheck=1
repo_gpgcheck=0
gpgkey=https://packages.cloud.google.com/yum/doc/yum-key.gpg
       https://packages.cloud.google.com/yum/doc/rpm-package-key.gpg
EOF

This was the result:

[wb@instance-1 yum.repos.d]$ sudo tee /etc/yum.repos.d/gcsfuse.repo > /dev/null <<EOF
> [gcsfuse]
> name=gcsfuse (packages.cloud.google.com)
> baseurl=https://packages.cloud.google.com/yum/repos/gcsfuse-el7-x86_64
> enabled=1
> gpgcheck=1
> repo_gpgcheck=0
> gpgkey=https://packages.cloud.google.com/yum/doc/yum-key.gpg
>        https://packages.cloud.google.com/yum/doc/rpm-package-key.gpg
> EOF

Complete!

I tested it just now on a fresh ne VM with CentOS 7 with default settings. I also used it as a startup script and it worked as intended.

Similar issue was discussed here but this approach didn't work for me.
