Support and News Forum

Dear Team,

I have searched the forum thru, but seem not to have any topic found, which would have answered my particular question.
therefore, I am opening this one, hope, it will help me by my problem.

I try to introduce the EVE NG to our company and have some kind of issue by the installation of it on bare metal.
in the past, and so far, the EVE NG was present here as the virtual machine, and recently we got the hardware for this, which is conform to HCL.
I am following up the cookbook for bare metal installation, but the description there seems to be dedicated to only old Ubuntu release.
Unfortunately, I am restricted to use a very new Ubuntu Server version as per Ubuntu official page, and not allowed to use old one in our environment, even at the beginning...
so I got the official ISO image from Ubuntu:
ubuntu-20.04.2-live-server-amd64.iso
and got it installed on my hardware:

I have followed up the cookbook instructions up to following point:

3.3.2 EVE Community Installation Phase 2

VE Community installation with the following one-line command and hit enter
wget -O - http://www.eve-ng.net/repo/install-eve.sh | bash -i
\\\

but after the execution of the abovementioned script I am NOT getting the EVE-NG Application installed.
it seems to be, that the new UBUNTU Server release has kind of uncompatibility issues in compare with the old one.

following is the log of the script execution:

I would say, that I need kind of step-by-step instruction with all packages, that need to be installed being listed separately.
than I will be able to install the necessary packages individually so, as it is compatible with the newest UBUNTU distribution.

thank you a lot in Advance!

it is very likely, that the issue is on the new kernel version uncompatibility with the old Library:

supposely the step-by-step instruction how to install the eve-ng Software on the Linux with the new kernel 5.4.0-72-generic #80-Ubuntu would help.

Dear EVE Team,
can someone kindly advise the situation?
that would be great!

All simple, do not use custom or newer kernel for eve,
Thats it

Hi Uldis,
Thank you for the confirmation.
does make any sense to consider Pro Version if the newest Linux&Kernel Version is kind of requirements?
Let me know about that if possible
Thank you and best Regards!

No it is not mate,
EVE ernel has too much bindings to the internal processes,
New kernel will give you nothing better or performance..
We are integrating new kernel support on the eve native support only when time comes and it has been matured...
If you will change it now, no one will predict that eve simply will stop work..
Sorry but we dont do thing like that

Hi Uldis,
thank you, Sir!
I got the point!
With best Regards!
