Certificate error

Hi, I’m trying to access Cockpit and I get this error on the screen:
“Packageless session unavailable. Install the cockpit-system package (and optionally other cockpit packages) on localhost to enable web console access.”
And when checking the logs I see this:
cockpit-tls: gnutls_handshake failed: A TLS fatal alert has been received.

What cockpit packages do you have installed? Please provide the results of:

rpm -qa | grep -i cockpit

For example on my system, I have the following for my requirements:

root@kvm:~# rpm -qa | grep cockpit | sort
cockpit-334.2-1.el9_6.x86_64
cockpit-bridge-334.2-1.el9_6.x86_64
cockpit-machines-328.1-1.el9_6.noarch
cockpit-packagekit-334.2-1.el9_6.noarch
cockpit-pcp-323.1-1.el9_5.x86_64
cockpit-storaged-334.2-1.el9_6.noarch
cockpit-system-334.2-1.el9_6.noarch
cockpit-ws-334.2-1.el9_6.x86_64

you might not need all of them, it just depends on what you will be using cockpit for. Eg cockpit-machines allows managing VM’s. That’s from a RL9 system, so you’ll need to check and see what RL10 packages need installing but it should be similar.

I have this:
admin@servidor:~$ rpm -qa | grep -i cockpit
cockpit-bridge-334.1-1.el10_0.x86_64
cockpit-packagekit-334.1-1.el10_0.noarch
cockpit-storaged-334.1-1.el10_0.noarch
cockpit-ws-334.1-1.el10_0.x86_64
cockpit-files-16-1.el10.noarch
cockpit-machines-328.2-1.el10_0.noarch
cockpit-system-334.1-1.el10_0.noarch
cockpit-334.1-1.el10_0.x86_64

The same error message on Fedora suggests doing:

dnf reinstall cockpit-system

if you can try that and let us know. Also, ensure these packages are installed:

dnf install polkit polkit-libs

I’ve already reinstalled it and downloaded the other two packages (which were already downloaded), and it still doesn’t work.
