Hello, I have a weird problem when I want to change settings in NoMachine.
I get the error:
Authentication failed, please try again.
My password is working in the terminal, etc. On the second machine, I have the same configuration and don’t have this error. I have researched the forum and the internet, trying different approaches like:
– https://forum.nomachine.com/topic/authentication-failing-when-unlocking-to-change-server-preferences
But I still get the same error. I have tried rebooting, restarting, and reinstalling NoMachine. Additionally, I noticed that I must log out with my Ubuntu by [removed] when I connect with NoMachine, or else I get an extended desktop. Below is a step-by-step guide for how I installed NoMachine on my Ubuntu:
– I installed Ubuntu Server minimal, and then:
# 1. Update your package lists
sudo apt update
# 2. Install LXQt
sudo apt install lxqt
# 3. Install Xorg (if not installed)
sudo apt install xorg
# 4. Download NoMachine package
wget https://download.nomachine.com/download/8.5/Linux/nomachine_8.5.3_1_amd64.deb
# 5. Install NoMachine package
sudo dpkg -i nomachine_8.5.3_1_amd64.deb
# 6. Fix missing dependencies
sudo apt -f install
I can confirm this problem persists for me on NoMachine 8.8.1, on Ubuntu 22.04. Really wish anyone could help with it.
We are not able to report your exact same error, but there is a similar issue which is reported here but related to the Moonlight theme: https://kb.nomachine.com/TR01U10758 which is linked in the topic from those listed above (https://forum.nomachine.com/topic/ubuntu-22-04-1-lts-authentication-failed-when-asked-for-admin-password).
What you could check is whether installing zenity helps,
sudo apt install zenity. If that doesn’t help, update to NoMachine 8.9 and let us know if the problem persists.I get this issue also on ubuntu 22.04 lts. I am running the “unity” desktop (no moonlight theme), and that may itself be the issue, as I can’t get VNC nor RDP to work either (for those I have performed the “keyring dance” which seemed to work ok). I tried the suggestion to install Zenity, but that had zero effect. If I didn’t dread the idea of setting back up all my RAID arrays, I would switch to Mint, and I may have to in the end. Does anyone know why this is occuring? Can I fix it by switching to xfce desktop?
@Britgirl – I am reproducing this problem as well on 22.04.3 with Wayland. You can use the same log for referencing – https://forum.nomachine.com/topic/how-to-speed-up-nm-server-startup-at-boot#post-45867
Please try the workaround here: https://forum.nomachine.com/topic/how-to-speed-up-nm-server-startup-at-boot#post-46160
