Description

Trying to generate a key with default options (and it seems with any other, too) fails every time.

Works on the command line and adding a subkey later does also work.

• werner added a comment.Feb 27 2026, 12:47 PM

Libkleo does not specify the curve in the parameter file becuase keyCurvve:isEmpty is asserted:

if (!d->keyCurve.isEmpty()) {
    keyParameters.push_back(serialize("Key-Curve", d->keyCurve));
}
• werner lowered the priority of this task from Unbreak Now! to High.Feb 27 2026, 2:54 PM

This is not "Unbreak now" because we have not released the software yet. Unbreak now should be used for bugs in deployed software but not during development.

Fixed. This regression was caused by changes made for T8056: Support config options RSAKeySizes and PGPKeyType for Kf6.
