Unable to upgrade to version 4

[defsecprof]

Hi,

I have successfully upgraded my test server from 3.2.6-1 to 4.0.1 following the manual. However my production server running exactly the same configuration (Debian 10.6, MongoDB 4.2.11, Elasticsearch 7.10.0) tells me that that I have already the latest version:

graylog-server is already the newest version (3.2.6-1).

I have run:

wget https://packages.graylog2.org/repo/packages/graylog-4.0-repository_latest.deb

dpkg -i graylog-4.0-repository_latest.deb
apt-get update &&  apt-get install graylog-server 

This is my list of packages:

dpkg -l | grep graylog
ic graylog-3.1-repository 1-1 all Package to install Graylog 3.1 GPG key and repository
ic graylog-3.2-repository 1-1 all Package to install Graylog 3.2 GPG key and repository
ii graylog-4.0-repository 1-2 all Package to install Graylog 4.0 GPG key and repository
ii graylog-server 3.2.6-1 all Graylog server

I have tried to remove the old version with: dpkg -r graylog-server, however when I run apt-get install graylog-server I am always getting the old version.

What am I doing wrong?

Thank you in advance for any help in resolving this one.

I have found a solution myself but I want to share in case somebody is experiencing the same issue.

Here is what I have done:

Edited /etc/apt/sources.list.d/graylog.list:
commented out the old entry and added this one:
deb [trusted=yes] https://packages.graylog2.org/repo/debian/ stable 4.0

Removed the old version:
dpkg -r graylog-server

Updated:

apt-get update && apt-get clean

Confirmed that apt could see the new version:

apt-cache policy graylog-server

Installed without any further issues:

apt install graylog-server

All working fine after that!

Ah, yeah. I was going to suggest this. The sources list file seems to biting a few folks right now. We might need to amend the docs to ensure that you remove the old repo first and then update to the newest.
