ProcessError (exited non-zero) localhost: net: (255)

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 " 🔒 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.

I'm also on Debian 12 (bookworm) and get the same error. If I open the browser console (Firefox), I see this additional error – maybe this is related?

ExitedProcess(Server(localhost), Command(["net","conf","showshare","global"], {"superuser":"try","binary":true,"err":"message"})) (exited 255):
stdout:
error getting share parameters: SBC_ERR_NO_SUCH_SERVICE

stderr:

ProcessError (exited non-zero): localhost: net:  (255)

[AlBundy33]

good point - this may be the issue 🤔

root@debian-lxc:~# net conf showshare
Usage:
net conf showshare <sharename>
root@debian-lxc:~# net conf showshare global
error getting share parameters: SBC_ERR_NO_SUCH_SERVICE
root@debian-lxc:~# net conf list
root@debian-lxc:~# net conf showshare global
error getting share parameters: SBC_ERR_NO_SUCH_SERVICE
root@debian-lxc:~#

[muellermartin]

My guess was right: The other error message from the browser console was related! Running net conf showshare global results in the same error (error getting share parameters: SBC_ERR_NO_SUCH_SERVICE) and net conf listshares showed no global configuration (only one share that I configured via cockpit-file-sharing.

I could solve this error by first commenting out the include = registry line in /etc/samba/smb.conf and then running sudo net conf import /etc/samba/smb.conf global. This imports the global configuration/share. After that the include = registry can be activated again. (Note: not disabling this line results in an infinite import loop)

Strangely I also had to install samba as it was no dependency of cockpit-file-sharing.

After that it seems to work :)

@muellermartin confirming those steps worked for me. The error is gone now.

[dimarcode]

@muellermartin confirming those steps worked for me. The error is gone now.

This works in the newest version of cockpit and Ubuntu 24.04?

It was in Debian 12 for me

[matjanss]

@muellermartin Worked for me aswell. Debian 12.

Why not simply try it? 🤔
If it's not working you can install an older version.
