I have an obstacle with that.

I lost my previous PGP key a year ago and created a new one, which is
not trusted yet by anyone [*]. I've backed this up now and have it
stored inside Nitrokey Pro 2 in order to prevent this happening again.

Now the problem is that in order to get a kernel.org account, I need
to be in the web of trust of the kernel maintainers.

I can request an accunt only after I see face to face another kernel
maintainers, so that I can proof that I am I.
