Gnupg return code 2 while trusting key

[Nichokas]

Describe the bug
The Python script should be updating the trust level, but it might be me; I can’t think of any way to fix it."
To Reproduce

gpg = gnupg.GPG()
cert="DACCF18B6800FCD0"
trust_levels = [("TRUST_FULLY", "Trusted"),("TRUST_NEVER", "NOT Trusted")]
trust = radiolist_dialog(
    title="Select a trust level",
    text="Selec a trust level for the selected key:",
    values=trust_levels
).run()
if trust:
    gpg.trust_keys(cert, trust)

File "/home/nichokas/Documents/gpg4td/venv/lib/python3.12/site-packages/gnupg.py", line 2276, in trust_keys
raise ValueError('gpg returned an error - return code %d' % p.returncode)
ValueError: gpg returned an error - return code 2

Expected behavior
Certificate with changed trust

Environment

• fedora linux 40, python 3.12
• v0.5.3

I suggest you enable logging and look at the portion of the log relating to the trust_keys() call. If you don't spot an obvious problem, post that portion of the log here.
