Hello, I have been having difficulty installing Samba. I first installed it in Ubuntu 18 LTS lxc container running on proxmox pve, through "apt install samba". However the version installed by this command was quite outdated and gave me the error "Can not dump core files; core path not specified" when i was trying to configure samba-ad-dc using "samba-tool domain provision --use-rfc2307 --interactive"
samba --version = 4.6.7

Since some online forums suggested it might be a release bug, i decided to try installing the latest samba (4.12.5) from source. I downloaded the tar ball, extracted, installed dependencies, run ./configure, make, make install; however samba did not install despite these commands indicating success.

I have tried installing from source on ubuntu 18 standalone desktop and i get a bunch of errors from ./configure

Will appreciate any input

Did you run the commands to manually install with sudo/root privileges?

yeah, all commands run as root

Is Ubuntu 18 a requirement? Can you use 20.04?
Reason I ask, is 20.04 "ships with Samba 4.11.x" https://wiki.ubuntu.com/FocalFossa/ReleaseNotes

Getting software from repo will also make your life easy down the road when you have to install patches.

Thanks for this. I didnt know that. Let me try 20 and see if i still get the same issues.

Installed Ubuntu 20.4 LTS template on lxc container (unprivileged), and NO it does not ship with samba as i had to install it.
#apt install samba //installs samba version 4.11.6
This version of samba still produces the same error: Unable to dump core files: core path not set

From the research online, it seems samba requests core access which provides it with real root rights so as to dump the files. With unprivileged containers which pick most of their settings from the host node, have this 'real root' disabled. The only way to run it is by using privileged containers.

My conclusion is that I cannot use containers since using an unprivileged container is NOT an option for me!

Can you post your smb.conf file

And also run testparm and copy the results to the post as well.

Ok, how will it help because its a lxc container and samba issue?!

Please excuse, I overlooked the most important statement above.

why on earth do you ignore the error message? You must configure core path. That's all. It is not related to samba, every version will require the mentioned core path.
Opening a new thread still will not solve it.
