System version
NethServer release 7.5.1804 (final)
Kernel release

The same problem

Latest kernel is 3.10.0-862.3.2.el7.x86_64, but the updates could be blocked by another package. If yum update throws “Error unpacking rpm package python-backports-ssl_match_hostname” follow the instructions pointed on the other solved topic.

I make yum update but responde No packages marked for update

yum makecache
yum update

or if it does not work, clear the cache and try again.

The solution to the post is partial, only solves the problem with the update of the python-backports-ssl_match_hostname package. The problem with the DPI module has not been solved. The installed kernel is not compatible and yum has no kernel updates.

There must be some settings that create the kernel update problem but I can not find it.

Do you have subscription? Maybe the update is delayed due to that.

Installed a new NS 7.5 instance from iso today.
After update kernel 862.3.2 was installed.

nDPI module and basic firewall installation without problem. No subscription so long (will follow).
could create a rule with facebook-dpi without problem.
So I don’t think this is general problem of NS 7.5.



No! I don’t have a subscription!

If I look for the installed kernels I find the compatible version:

# rpm -qa kernel

I think it’s tied to a grub configuration but I’m not able to change it

@pasing, Did you reboot the server in order to load the new kernel?

Strange, I restarted it a few times only now it was successful.
Thanks for your patience and support, @dnutan!
