How to add PPA repositories to preceed?

Question

linux

Good afternoon. Tell me why this construction does not work in the preceed file. How to add third-party repositories to install packages that are not part of the main repositories.



I didn't find anything on the Internet. Only information on how to disable key verification for turnips. In this case, the installer simply writes that it cannot install the software.
Here

And this is an example from GitHub on adding PPA Ansible


Thank you all for your advice!!!

I'm no longer with Ubuntu, but while I was with Linux, I managed to tinker with the same problem a month ago. Like a normal user.
He perverted as best he could - and tossed pre-downloaded keys, and somehow bypassed the scripts. Didn't fence.
The point is not in the design and not in the fact that it is necessary to turn off the check .
In new versions of Ubuntu, Linux Mint and the like, the security policy of external repositories has changed a lot - so much so that a key that is not liked on a preliminary attempt to connect will be rejected long before the allow_unauthenticated check works.
I did not find any bypass guides for the end user - some wonderful changes are needed on the side of the added PPA repository.
An end user like you and me seems to only be able to download the compiled package and install it manually (.tar.gz) and/or through the Software Manager (.deb and the like). Naturally, it will not be updated automatically...
Well, or rollback to some old version of Linux, it should not have this problem.
