|The problem=I have always been interested in CFD, so thought I would have a play to see how it works for a car. But I had an issue with apt-key, this explains how to fix the apt-key warning

{{How to guide
|Device=Lenovo
|Operating system=Ubuntu
|Software=InsightCAE
|Guidance=I wanted to install InsightCAE<ref>https://silentdynamics.de/en/oss-cae/#insight_install</ref>. But I had some issue, so had to install from source in the end.

But this will cover off how I expierienced the issue and how I fixed it.

Open terminal and add the repository:
 sudo apt-key adv --fetch-keys <nowiki>http://downloads.silentdynamics.de/SD_REPOSITORIES_PUBLIC_KEY.gpg</nowiki>
This threw an error:
 Warning: apt-key is deprecated. Manage keyring files in trusted.gpg.d instead (see apt-key(8)).
<div>When I try and update, I get:
</div>
 W: <nowiki>http://downloads.silentdynamics.de/ubuntu/dists/jammy/InRelease</nowiki>: Key is stored in legacy trusted.gpg keyring (/etc/apt/trusted.gpg), see the DEPRECATION section in apt-key(8) for details.
<div>
Which means it won't install.

First, we need to seperate the key from the trusted.gpg, run:
 <code>sudo apt-key list</code>
This is the one I'm interested in:
</div>
[[File:APT key list.png|none|frame|APT key list - the problem entry]]


We need to export it.

Run:
[[File:Export apt-key for insightcae.png|alt=Export apt key for InsightCAE|none|frame|Export apt key for InsightCAE]]
Apologies I can't do the full code here. MediaWiki doesn't like pipes outside brackets.

You will get the error that apt-key has been depreciated, but, when you next run:
 sudo apt update
Job done, you will no longer get the error.
