The MySQL APT GPG key expired on Feb 16, 2017, making it impossible to install or upgrade Debian packages from the Oracle MySQL APT repository.

How to repeat:
# apt-get update

reports the following error:

W: GPG error: http://repo.mysql.com jessie InRelease: The following signatures were invalid: KEYEXPIRED 1487236823 KEYEXPIRED 1487236823 KEYEXPIRED 1487236823

# apt-key list

shows the expired key:

pub   1024D/5072E1F5 2003-02-03 [expired: 2017-02-16]
uid                  MySQL Release Engineering <mysql-build@oss.oracle.com>

Suggested fix:
Update the GPG key for the Oracle MySQL APT repository and update the mysql-apt-config Debian package accordingly.

Hello Daniel Bakken,

Thank you for the report and feedback!

Sorry for the trouble. We're getting apt-config updated with the new key.
Workaround: (run as root)

apt-key del A4A9406876FCBD3C456770C88C718D3B5072E1F5 # Delete the old key
export GNUPGHOME=$(mktemp -d) # This just sets it up so the key isn't added to your actual user
gpg --keyserver ha.pool.sks-keyservers.net --recv-keys A4A9406876FCBD3C456770C88C718D3B5072E1F5 # Download the new one
gpg --export A4A9406876FCBD3C456770C88C718D3B5072E1F5 /etc/apt/trusted.gpg.d/mysql.gpg # Add it to the list of apt keys
apt-key list # This should now show the updated key

Easier one-liner, like in MySQL Docs:

$ sudo apt-key adv --keyserver pgp.mit.edu --recv-keys A4A9406876FCBD3C456770C88C718D3B5072E1F5
Executing: /tmp/tmp.yJ1Cs6jTjh/gpg.1.sh --keyserver
gpg: requesting key 5072E1F5 from hkp server pgp.mit.edu
gpg: key 5072E1F5: public key "MySQL Release Engineering <mysql-build@oss.oracle.com>" imported
gpg: Total number processed: 1
gpg:               imported: 1

We have a simpler way to update the key in our docs, actually:
sudo apt-key adv --keyserver pgp.mit.edu --recv-keys 5072E1F5

Whops, didn't see your comment. Thanks :)

Thanks for the workaround. Now I won't have this problem again until 2019. ;)

We've also updated the mysql-apt-config package to get the key from a public keyserver (which in this case would mean it would simply be a matter of running dpkg-reconfigure to update it).

Note: If you are unable to open port 11371 you cannot upgrade mysql-apt-config successfully since it now forces the getting of the new keyfile (even if you've manually replaced it at the command line).

Since the "gpg" program allows you to specify a port it would be ideal if this was possible here. Or alternatively, you could just try to get the key over port 80 if the default port fails.

With port 11371 blocked you can use:

sudo apt-key adv --keyserver hkp://pgp.mit.edu:80 --recv-keys 5072E1F5

How do I inject that other URL into the dpkconfigure/apt-get update execution?

@Hendrik Visage you could temporary add an iptable DNAT rule:

iptables -t nat -A OUTPUT -p tcp --dport 11371 -j DNAT --to-destination

update/install the package und remove the rule again

Flush Example:
iptables -t nat -F
