updating git ppa error - no valid OpenPGP data found on Debian

I'm trying to update the git version on a Debian 10 (buster) machine and running into issues with gpg key.

> sudo add-apt-repository ppa:git-core/ppa
 The most current stable version of Git for Ubuntu.

For release candidates, go to https://launchpad.net/~git-core/+archive/candidate .
 More info: https://launchpad.net/~git-core/+archive/ubuntu/ppa
Press [ENTER] to continue or ctrl-c to cancel adding it

gpg: keybox '/tmp/tmpfqaimru3/pubring.gpg' created
gpg: /tmp/tmpfqaimru3/trustdb.gpg: trustdb created
gpg: key A1715D88E1DF1F24: public key "Launchpad PPA for Ubuntu Git Maintainers" imported
gpg: Total number processed: 1
gpg:               imported: 1
gpg: no valid OpenPGP data found.

I also tried to manually add key, but still end up with same error after adding the key successfully.

> sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys A1715D88E1DF1F24
Executing: /tmp/apt-key-gpghome.pwYjc1J0zy/gpg.1.sh --keyserver keyserver.ubuntu.com --recv-keys A1715D88E1DF1F24
gpg: key A1715D88E1DF1F24: public key "Launchpad PPA for Ubuntu Git Maintainers" imported
gpg: Total number processed: 1
gpg:               imported: 1

And also:

> gpg --export  A1715D88E1DF1F24 | sudo apt-key add  -
gpg: WARNING: nothing exported
gpg: no valid OpenPGP data found.

Not sure what I'm doing wrong. I've also done update a few times.

> sudo apt-get update

I tried this in a docker container and

sudo add-apt-repository ppa:git-core/ppa

doesn't work there as well. But

sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys A1715D88E1DF1F24
sudo gpg --export  A1715D88E1DF1F24 | sudo apt-key add  -

works.

note that the only difference to your command is, that i am invoking the gpg --export command with sudo.

The explanation for this behaviour is, that

sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys A1715D88E1DF1F24

imports the key into the keyring of root. So if you invoke the command without sudo gpg cant find the key you've imported.

As in this issue, check if you see expired keys with sudo apt-key list

Depending on what you see in /etc/apt/sources.list.d/, you could infer the URL of the 'gpgkey' to import.

curl -L https://.../git-core/gpgkey | sudo apt-key add -
