Updated VirtualBox via Oracle repos, but new Extension Pack not offered

[kalpana]

In light of this information, I switched from manually downloading/installing the VirtualBox deb to using the Oracle repositories. Today I got the first VirtualBox update by this method -
Code:

Code Select Expand

Upgrade: virtualbox-6.1:amd64 (6.1.38-153438~Ubuntu~jammy, 6.1.40-154048~Ubuntu~jammy)
That part worked. But when I start the new VirtualBox, it does not prompt me to get the matching Extension Pack version? And it still has 6.1.38 extension pack?
Code:

Code Select Expand

$ VBoxManage list extpacks
Extension Packs: 1
Pack no. 0:   Oracle VM VirtualBox Extension Pack
Version:      6.1.38

$ VBoxManage --version

How to get the notification ajgreeny described in the linked post?
