Tumbleweed – NX> 704 ERROR: Unsupported operating system ‘linux’

[jayltee]

Running Tumbleweed with all updates as of November 2017. Tried to install NoMachine v5.1.62 (which I have been successfully running with Leap42.2) and it fails as below. I get the same with 6.0.62 so it’s not version specific.

To resolve this I had a look in the nxserver script and see it does the following to work out the OS/Distribution:
getLinuxNameFromFiles ()
{
#Function returns:
# 0 : OS name is found
# 1 : OS name not found

wantedOS=”$1″
searchedFile=””
ret_getLinuxNameFromFiles=”1″

if [ -f /etc/lsb-release ];
then
searchedFile=”/etc/lsb-release”
elif [ -f /etc/os-release ];
then
searchedFile=”/etc/os-release”
elif [ -f /usr/lib/os-release ];
then
searchedFile=”/usr/lib/os-release”
else
return 0
fi

os_out=${GREPCOMMAND} ‘\(\(NAME\)\|\(DISTRIB_ID\)\)=.*'”${wantedOS}”‘.*$’ “${searchedFile}” 2>/dev/null || test 1

if [ “x${os_out}” != “x” ];
then
ret_getLinuxNameFromFiles=”0″
fi
}
###########
The difference with Tumbleweed and Leap42 is that TW has /etc/lsb-release and Leap does not. As this file is found first it is used in the next stage of the script but it does not have the distribution in it – it looks like this:
LSB_VERSION=”core-2.0-noarch:core-3.2-noarch:core-4.0-noarch:core-2.0-x86_64:core-3.2-x86_64:core-4.0-x86_64″

This leaves the script without knowledge of the distribution and so fails. I simply removed this file and the installation was fine as all Suse distributions have the “standard” /etc/os-release file.

Maybe someone can fix the /usr/NX/scripts/setup/nxserver script so that /etc/lsb-release is not there (or at least move to the end)? If not, I hope this at least helps someone with the same issue as it could hit other distributions.

Cheers,
JT

Thank you for reporting this problem and the detailed analysis. We are still investigating this issue because we weren’t able to reproduce it. We will open a Trouble Report and inform you about it as soon as possible.

I have exactly the same problem

Thank you for reporting this problem. We have opened a Trouble Report to track this issue: https://www.nomachine.com/TR11O08293. To let the installation complete without errors please temporarily change name or backup and remove “/etc/lsb-release” file (it can be restored after installation/update of NoMachine) as the user “jayltee” instructed.

 

To be notified when the fix is released, you may register to the ‘Notify me when the TR is closed’ option.
