the fingerprint `D6:41:54:2B:F7:E7:73:F5:BA:7B:97:79:4D:E0:14:21 2F:49:91:AE:97:15:EE:42:0B:16:F3:04:35:84:17:35` might be used in debug builds years ago, before doing real releases. but not sure. i checked quite some recent apk, and none of them uses that fingerprint; debug apk all seem to have a different fingerprint. the only used fingerprint is the other one. the validation itself still works as always: ``` ~/Downloads % keytool -printcert -jarfile deltachat-gplay-release-2.35.0.apk Signer #1: Certificate #1: Owner: O=merlinux GmbH, C=de Issuer: O=merlinux GmbH, C=de Serial number: 36aacf4d Valid from: Tue Feb 12 02:41:06 CET 2019 until: Sat Feb 06 02:41:06 CET 2044 Certificate fingerprints: SHA1: 4D:8C:4D:3A:DA:25:46:DE:51:D5:9A:1F:3F:A9:04:84:72:3B:C6:69 SHA256: 35:5B:E2:C3:8E:C6:73:83:C1:02:FB:E0:3E:84:C4:BC:3E:6F:89:06:F8:D3:66:91:4F:84:52:82:08:13:2A:EE ```

There was a problem hiding this comment.
Didn't check myself which one is the valid one, but removing outdated fingerprints sounds like a good idea.
