Unable to change expiration date on primary key

[Jesse Hathaway]

I have a key with two subkeys, the two subkeys have no expiration. I am
trying to remove the expiration date on the primary key, but the
suggested commands don't seem to have any effect and more strangely
don't seem to return any error messages or a non-zero exit code. I have
tried using both using the gpg console and the --quick-set-expire
option, but both have no effect. I have also tried extending the
expiration date, but the results are the same:
