Recommend using the PPA in the wordpress website as well

Is your feature request related to a problem? Please describe.

On the primary website (WordPress.com), there is no warning about Ubuntu and its derivatives.

Describe the solution you'd like

Write the following on the Downloads page on WordPress.com as well:

For Ubuntu 18.04+ and derivatives (such as Linux Mint), users are strongly
advised to use the
PPA.

How to add and install from the PPA:

sudo add-apt-repository ppa:deki/firejail
sudo apt-get update
sudo apt-get install firejail firejail-profiles

Reason: The firejail package for Ubuntu 20.04 has been left vulnerable to
CVE-2021-26910 for months after a patch for it was posted on Launchpad:

• CVE-2021-26910
• firejail version in Ubuntu 20.04 LTS is vulnerable to
  CVE-2021-26910

See also https://wiki.ubuntu.com/SecurityTeam/FAQ:

What software is supported by the Ubuntu Security team?

Ubuntu is currently divided into four components: main, restricted, universe
and multiverse. All binary packages in main and restricted are supported by
the Ubuntu Security team for the life of an Ubuntu release, while binary
packages in universe and multiverse are supported by the Ubuntu community.

Additionally, the PPA version is likely to be more recent and to contain more
profile fixes.

  repos?

  derivatives

Additional context

From what I understand, this may also apply to firetools, in which case the WordPress.com Downloads page for firetools and the README on GitHub would also need to be modified.

Having the Ubuntu PPA details on the primary website too makes sense. If I'm not mistaken only @netblue30 can take care of that.

From what I understand, this may also apply to firetools, in which case the WordPress.com Downloads page for firetools and the README on GitHub would also need to be modified.

Firetools repo offers .deb's on its releases page. I don't see any firetools package on the PPA though.

It sounds like a good idea to have all firejail-related tools in the same PPA.
One consideration is that firetools depends on qt, which might be tricky to
deal with if different Debian versions ship with different qt versions, though
I'm not familiar with maintaining something like that.

@reinerh Thoughts?

[reinerh]

there was no need yet to have firetools in the PPA, as firetools is not released so frequently.
but if there is interest, I can upload it as well.
I think firetools does not have a tight requirement on certain Qt versions, so it might work without much problems.

I just remembered that I actually already uploaded firetools to the PPA: https://launchpad.net/~deki/+archive/ubuntu/firejail
0.9.72 is available for Ubuntu 20.04, 22.04 and 22.10.

I see, but is it important to have matching versions of firejail/firetools?

For example, if a user installed firejail 0.9.72 in the PPA and firetools
0.9.70 from the distribution (in case it was not in the PPA).
