How do I install a specific Focal version like 245.4-4ubuntu3.10?

br flag

I am currently using Docker to install Ubuntu 20.04 like this:

FROM ubuntu:20.04

I ran some security audit and there are a few vulnerabilities and it says they are fixed in version

245.4-4ubuntu3.10

and my current installed version it says is:

245.4-4ubuntu3.7

Are these tags for nightly builds? I am just referencing ubuntu 20.04 as you can see so curious as to how I would install this specific version of 245.4-4ubuntu3.10 using Docker.

@pLumo Yes it is a libsystemd0 issue: CVE-2021-33910

This version number is not from Ubuntu itself, but from one of its packages. They have the ubuntu name in it as they are specifically built for Ubuntu possibly with backports.

Actually, this seems to be systemd.

Current version in repos is 245.4-4ubuntu3.11, so you could just run sudo apt update && sudo apt upgrade -y after you started your container or during build in your Dockerfile.

Not sure, why the ubuntu docker image is outdated... Doucker hub says "Last pushed 13 days ago", which is before the fix came to Ubuntu at "Tue, 20 Jul 2021 07:39:51 -0400".

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
