Question about key verification with GnuPG 2.2.25

[gnupgpacker]

Hello,
the --verbose options gave me some more unusual information:

gpg: Schlüssel 22EEE0488086...F: Ungültige Eigenbeglaubigung für User-ID "[jpeg image of size 7915]"
gpg: Schlüssel 22EEE0488086...F/CE7911B7FC04...F: Ungültige Unterschlüssel-Anbindung
gpg: key 41E7044E1DBA...9: number of dropped non-self-signatures: 60
gpg: Schlüssel 4E2C6E879329...0/7017ADCEF65C...6: Mehrfache Unterschlüssel-Anbindung entfernt
gpg: Im Unterpaket des Typs 28 ist das "critical bit" gesetzt
gpg: compacting user ID "<pgpCA at ct.h...e.de>" on key 2BAE3CF6DAFF...0: ungültig

Which error causes following warnings:
gpg: signature packet: hashed data too long
gpg: read_block: read error: Ungültiges Paket

Thanks once more, best regards, Chris
