The last attempt to update cPanel & WHM was blocked

Hi all,

I need your urgent help. I have got a problem with upgrading on my server as I have got an error:

Code:

A system upgrade was not possible due to the following blockers:

[/LIST]

I have also tried this:

/scripts/upcp –force


It still get the same results. I cannot be able to upgrade it.

I don't really know what to do.

Can you please advice me what I would need to do in order to upgrade it??

Thanks in advance

 

Yes I am using CentOS 6.9

Do you know what I need to do?

 

Oh right, I have checked my centos version via putty using the commend:

/etc/centos-release


It said "Permission denied".

Do you know why and how I can fix this?

 

On the top of the WHM, it said that my centos version is CENTOS 6.9 i686 virtuozzo.

I have tried to upgrade it but it wont let me as something has been blocked.

Do you know what I need to do to unblock it so I could upgrade it?

 

Oh ok thank you for your advice. I am going to upgrade it to 64-bit operating system.

Do you recommend if I should upgrade to CentOS 6.9 64-bit or CentOS 7 64-bit??
