Hello aims2019 ,
so these are actually two questions.
unknown locale: UTF-8what's the output of the locale command?
can't find uninstallerso SAV has been installed and /opt/sophos-av/ exists but does not contain uninstall.sh? What does it contain?
In reply to QC:
so SAV has been installed and /opt/sophos-av/ exists but does not contain uninstall.sh? What does it contain?
there is etc folder and update
In reply to aims2019 aims:
looks ok as far as I can tell. Perhaps DouglasLeeder can tell what might be wrong.
The medium installer has failed, because python doesn't like the locale setting. This leaves some bits from the initial thin installer download present in /opt/sophos-av, but those can be deleted without any problems.
Your locale looks reasonable from this reply, so I'm not sure where it's going wrong - it's ending up with "UTF-8" which isn't parsable.
Let's have a look at the environment:
FYI: This is the wrong group for Linux questions...

Now the problem is
Updating directly from Sophos.
Extra files updating is disabled. You can change updating settings using /opt/sophos-av/bin/savsetup.
Installing Sophos Anti-Virus....
Selecting appropriate kernel support...
When Sophos Anti-Virus starts, it updates itself to try to find a Sophos kernel interface module update. This might cause a significant delay.
Sophos Anti-Virus starts after installation.
On-access scanning not available. It was not possible to obtain or build suitable kernel support because kernel headers are not installed.

Yes, you need to install kernel headers, gcc and make to build Talpa for your kernel.
Thanks for the reply . If you give some guidelines it would be great
Here is the KBA describing the situation: https://community.sophos.com/kb/en-us/13503
Unfortunately different distributions have different package management tools, and name the packages differently, and I don't know SuSE well enough to advise what is required, beyond the generic information.
The qrticle says if we are above version 10.5 , we can use fanotify .
any pros and cons ?
If you click the link: https://community.sophos.com/kb/en-us/118216
That includes the limitations of fanotify.
I am not a linux expert . it would be great if you can give some idea how to manually compile talpa
Before running the the installer and to enable it to compile custom kernel modules, the following must be installed:
Most distributions provide a kernel-headers package which must also be installed. These distributions also provide all the required kernel sources to compile.
Note: For SuSE based distribution you will need the package kernel-syms from the running kernel version.
In the above what exactly they are saying
They are saying you need to install kernel headers, gcc and make.
I'm afraid I don't know SuSE well enough to advice you how to install packages or which packages are required.
I enabled fanotify , and tried to restart the service . after that the server showing red color instead of green
Real time protection disabled
I don't know what is going on
I think you should probably raise a support request, as I don't know what's happening with your system and they are more likely to be able to help you.
This is from another server (attached ) here is the screenshot
