Hi,

I downloaded the latest RC release from the provided link

https://github.com/roundcube/roundcubemail/releases/download/1.4.0/roundcubemail-1.4.0.tar.gz

I then downloaded the signature

https://github.com/roundcube/roundcubemail/releases/download/1.4.0/roundcubemail-1.4.0.tar.gz.asc

When I try to validate the signature gpg tells me:

gpg --verify roundcubemail-1.4.0.tar.gz.asc
gpg: assuming signed data in 'roundcubemail-1.4.0.tar.gz'
gpg: Signature made za 09 nov 2019 21:30:45 CET
gpg:                using RSA key 8970E37A698AF775D87D590DC2946A9609CD56B4
gpg:                issuer "devs at roundcube.net"


This shows that the signer has the key id:

8970E37A698AF775D87D590DC2946A9609CD56B4

However according to the website the (short) key ID should be:

41C4F7D5

The download link for the signing key
(https://roundcube.net/download/pubkey.asc) matches the above short key id:

F3E4C04BB3DB5D4215C45F7F5AB2BAA141C4F7D5

So either the packages have been signed with a different roundcube devs
key or the packages have been modified (or I'm doing something stupid :)

Any idea?


Kind regards,

Martijn Brinkers
