Linux installation with perl script fails on Red Hat family distributions with localpkg_gpgcheck enabled in /etc/dnf/dnf.conf

Describe the bug

The glpi-agent RPM packages are not signed, but the perl installation script doesn't pass the --nogpgcheck flag to dnf when trying to install it, making dnf fail on installs where localpkg_gpgcheck = 1 has been configured in /etc/dnf/dnf.conf or /etc/yum.conf.

I'm not sure if localpkg_gpgcheck being true is the default on RHEL/CentOS Stream 9, but at least with the ANSSI-BP-028 minimal SCAP profile applied it is set (see https://static.open-scap.org/ssg-guides/ssg-rhel9-guide-anssi_bp28_minimal.html#xccdf_org.ssgproject.content_rule_ensure_gpgcheck_local_packages).

To reproduce

1. Get a RHEL/CentOS Stream 9 machine running
2. Add localpkg_gpgcheck = 1 in /etc/dnf/dnf.conf
3. Download the latest published linux perl installation script
4. Execute it with perl glpi-agent-X.X-linux-installer.pl
5. Watch dnf refuse to install the downloaded RPM because the signature is missing

Expected behavior

dnf should not fail to install the downloaded glpi-agent RPM.

The RPM should ideally be signed and the perl script should import the RPM public signing key, but it may not be feasible in the foreseeable future so instead you could add the --nogpgcheck flag to the dnf install command here

$self->{_dnf} ? "dnf -y install @rpms" : "";

like it’s done with the openSUSE installation --allow-unsigned-rpm just above.

Hi @PlqnK

the question has still been discussed in this discussion: #723

To me, it's a bad idea to add --nogpgcheck as this will prevent also this check on dependencies even where it's not a problem.

But maybe adding --setopt=localpkg_gpgcheck=0 can work.

[g-bougard]

I confirm this works. You can modify the installer this way:

sed -ie 's/dnf -y install/dnf -y install --setopt=localpkg_gpgcheck=0/' glpi-agent-1.11-linux-installer.pl
