1. You can only delete signatures you have made yourself.
2. If you could delete the unknown sig's, they would be replaced next time =
key was imported from a keyserver
3. You can ignore any unknown signatures by using --check-sigs instead of=20

Everyone has that. You'd have to run a keyserver to get close to all, even=
then there are some keys that are simply not obtainable.

The best you can achieve is to simply ignore them.

You can't even do it by hand.

You're not cleaning these keys - you're breaking them.

Negligible. It's the public keys that take up the room - an unknown signatu=
can only take a tiny amount of disk space. Some public keys are 4kb -=20
especially if images are involved.
Try it, sign a key LOCALLY and compare the filesize before and after using:
gpg -a --export <keyid>
=46ar better to only keep the keys you really need. Thereagain, if your quo=
so close that 4kb makes a significant impact, shouldn't you look somewhere=
else for the offending files??? You'll find a whole host of much larger=20
