Sebastian Marsching commented on CASSANDRA-19110:
-------------------------------------------------
[~rtib] Keys in {{/etc/apt/keyrings}} are not trusted globally. This is in
contrast to the keys in {{{}/etc/apt/trusted.gpg.d{}}}. I do not know about the
ones in {{/usr/share/keyring}} – they might be).
I think that avoiding globally trusted keys was the main motivation behind
deprecating {{apt-key}} and {{{}/etc/apt/trusted.gpg{}}}. The Man page of
{{apt-key}} (on Ubuntu 22.04) says:
{{ /etc/apt/trusted.gpg.d/}}
{{ File fragments for the trusted keys, additional keyrings can be}}
{{ stored here (by other packages or the administrator).
Configuration}}
{{ Item Dir::Etc::TrustedParts.}}
{{ /etc/apt/keyrings/}}
{{ Place to store additional keyrings to be used with Signed-By.}}
So {{/etc/apt/keysrings}} seems to be the corrrect place.
> apt-key deprecation, replace with gpg --dearmor in the docs.

> the command `apt-key` is deprecated and soon to be removed, especially on
> Ubuntu.
> the directory `/usr/share/keyrings` for shared keys are also being removed.
> I suggest to convert the docs from
> {code:java}
> curl https://downloads.apache.org/cassandra/KEYS | sudo apt-key add - {code}
> to a simpler command:
> {code:java}
> curl https://downloads.apache.org/cassandra/KEYS | sudo gpg --dearmor -o
> /etc/apt/keyrings/cassandra-archive-keyring.gpg {code}
> The path `/etc/apt/keyrings` doesn't exists by default on Ubuntu 20.04 but it
> does on 22.04.
> I also suggest to add the source.list.d text from
> {code:java}
> $ echo "deb https://debian.cassandra.apache.org 42x main" | sudo tee -a
> /etc/apt/sources.list.d/cassandra.sources.list
> deb https://debian.cassandra.apache.org 42x main{code}
> to
> {code:java}
> $ echo "deb [signed-by=/etc/apt/keyrings/cassandra-archive-keyring.gpg]
> https://debian.cassandra.apache.org 42x main" | sudo tee -a
> /etc/apt/sources.list.d/cassandra.sources.list
> deb [signed-by=/etc/apt/keyrings/cassandra-archive-keyring.gpg]
> https://debian.cassandra.apache.org 42x main {code}
> I have made a [PR|https://github.com/apache/cassandra/pull/2936]
> I have tested the gpg --dearmor on a VM with Ubuntu 22.04 myself recently and
> it works just fine.
