Hello gasde,

We weren’t able to reproduce the problems in our laboratory.
Could you gather logs from the affected host like it’s described in:

https://www.nomachine.com/DT10O00163#1.1

and send to forum[at]nomachine[dot]com please?

Hello fr2

Looks like you have a problem with creating a profile of user nx.
There are 2 possible reason:

1. Do you use domain users/LDAP/ActiveDirectory? Do you have non
standard restrictions for users?

2. It’s possible that default user profile on your host might be
corrupted. You can try to create few user accounts and check if
it’s possible to login on their desktops. If you experience any
problems, please refer to this Stack Overflow thread:

Hello resmi,

Looks like your issue is related to a presence of nx user.
Probably user nx was removed during the installation process.

Do you use domain users/LDAP/ActiveDirectory? Do you have non
standard restrictions for users?

A standard set of logs will be helpful. Gather them like is
described in:

https://www.nomachine.com/DT10O00163#1.1

and send to forum[at]nomachine[dot]com.

Hello apfaffman,

You are right, looks like your issue is related to presence of nx user
From logs looks like in the beginning of installation the user had
existed:

NX> 700 Running: /usr/sbin/chown nx:wheel ‘/Applications/NoMachine.app/Contents/Frameworks/etc/update.cfg’.
NX> 700 Result: OK.

but in the next phase there where problems:

NX> 700 Running: /usr/sbin/chown nx:wheel ‘/Applications/NoMachine.app/Contents/Frameworks/etc/guests.db.lock’.
NX> 700 ERROR: Cannot change ownership of: /Applications/NoMachine.app/Contents/Frameworks/etc/guests.db.lock to: nx:wheel.

Looks like the user nx was removed during installation process.

Do you use domain users/LDAP/ActiveDirectory? Do you have non
standard restrictions for users?

Hello david555

Probably your problem is related to SELinux. To check this you can:

1) temporally set permission mode

sudo setenforce 0

2) run NoMachine:

sudo /etc/NX/nxserver --restart

3) try to reproduce the problem,

4) set SELinux’s enforce mode:

sudo setenforce 1

if you aren’t able to reproduce the problem, then we check deeper
SELinux logs.

Anyway a standard set of logs will be helpful. Gather them like is
described in:

https://www.nomachine.com/DT10O00163#1.1

and send to forum[at]nomachine[dot]com.

Hello,

The problem is related to ‘install’ command.
Probably the standard command was replaced by a link/wrapper to apt.
Could you run:

/bin/install --help

It should looks like this:

$ install --help
Usage: install [OPTION]... [-T] SOURCE DEST
or:  install [OPTION]... SOURCE... DIRECTORY
or:  install [OPTION]... -t DIRECTORY SOURCE...
or:  install [OPTION]... -d DIRECTORY...

This install program copies files (often just compiled) into
destination locations you choose........

The default location of original ‘install’ program in Ubuntu 16.04 is:

/usr/bin/install

Hello Carlos,

During detecting name of Administrator’s group something went wrong.
Do you use ActiveDirctrory/LDAP/domain users?

To investigate the problem I need output from these commands:

net localgroup

net user nx

and a file adminGroup.txt from this:

"C:\Program Files (x86)\NoMachine\bin\nxdisplay.exe" --admingroup > adminGroup.txt

You can send the outputs and the file to forum[at]nomachine[dot]com.

Hello Sergey Slizovskiy,

Generally you can install a package with the patch having only NoMachine access.

If you are attached by NoMachine to physical session – the session is visible on physical screen. You can run terminal and install update package. You will be disconnected but after several minutes, when update finished you should be able connect again.

If you are not sure that you are running physical session or you are running virtual NoMachine session, you can install ‘screen’ program:

sudo apt update
sudo apt install screen

then run screen session -> execute in terminal:

screen

and in the screen session run NoMachine update:

sudo dpkg -i nomachine_6.7.6_41_amd64.deb

you will be disconnected, and after update finished you can connect by NoMachine again.

As safe as updating NoMachine is, there is a risk that something totally unexpected could happen. This could affect the possibility of connecting via NoMachine.

Hello

I assume, that you have now uninstalled NoMachine.
Please run this commands and preserve output of them:

sudo systemctl stop nxserver.service
sudo systemctl disable nxserver.service
sudo rm /etc/systemd/system/nxserver.service
sudo rm /usr/lib/systemd/system/nxserver.service
sudo rm /etc/init.d/nxserver.service
sudo rm /etc/init.d/nxserver
sudo systemctl reset-failed nxserver.service

After executed this commands if you still get the same error, please
show us the commands output.

Hello Amivaleo

Looks like really something went wrong during uninstallation. I think that the quickest way to solve your problem is to install again and uninstall NoMachine following the regular procedure. Please follow these steps:

1) remove leftover dirs:

sudo rm -rf /usr/NX /etc/NX /var/NX

2) install again:

sudo rpm -i nomachine_6.7.6_11_x86_64.rpm

3) uninstall:

sudo rpm -e nomachine

[zaq]

Hello,

Most possible is that you had corrupted default user profile (point 4). When you have this issue you can create a new user
account but you can’t log in:
