Bug Info

Describe the bug Installed latest version in Rocky 9.4 with cockpit 311.2 and now I get this error when opening the samba-page

ProcessError (exited non-zero)

localhost: net:  (255)

this is a new lxc container - so I don't have any shares configured

Does the user you logged into cockpit as have administrative access (e.g. a sudoer)? Check the top right part of the cockpit window to see if it says "Administrative access" or " :lock: Limited access"

[AlBundy33]

yes, of course - downgrading to the previous version works as expected (no error message and global settings are visible)

in terminal I can run net conf commands without error.

@AlBundy33 same issue here with debian 12 on bare metal, which version did you use to get rid of the error?

[AlBundy33]

on rocky the latest working version is 3.3.7-1

[timwhite1]

on rocky the latest working version is 3.3.7-1

This worked for me on Alma Linux 9.4 as well.

Needed to block updates to the package to prevent pulling back in 4.2.5 (until new features are fully functional in a few weeks)

Install older version 3.3.7 Cockpit File Sharing plugin

wget https://github.com/45Drives/cockpit-file-sharing/releases/download/v3.3.7/cockpit-file-sharing-3.3.7-1.el8.noarch.rpm sudo dnf install -y cockpit-file-sharing-3.3.7-1.el8.noarch.rpm

Lock updates for the plugin to avoid reinstalling newer buggy version

cp /etc/dnf/dnf.conf /etc/dnf/dnf.conf.bak #backup the original dnf config file if ! grep -q '^exclude=cockpit-file-sharing' /etc/dnf/dnf.conf; then echo 'exclude=cockpit-file-sharing' | sudo tee -a /etc/dnf/dnf.conf > /dev/null fi

Note this simply adds an exclude line to the end of dnf.conf

# exclude=cockpit-file-sharing

I was having the same issue. The exact same error when opening the samba page, and no global settings available for configuration in the gui. Rolling back to 3.3.7 worked for me as well. Logged in as root on brand new LXC container in proxmox.

The same problem also occurred on Ubuntu 24.04.1 LTS. This is my solution. I hope it will be helpful to those in need.

Isnt this just installing an older version to fix the issue temporarily?

Yes, fix the problem by installing an older version. If you need to use the new feature iSCSI, this is not a good solution.
