I cannot downgrade php to 8.4 because that will break a lot of services. So i have to upgrade roundcube to 1.7.x. Ubuntu does not provide a roundcube package other than 1.6.11, and it seems to plan  to continue so for the next release. So i need a source for a recent roundcube package to avoid an install from sources. Are there any?

Kind regards,

official downloads are available from the website and GitHub

Dear JohnDoh,

perhaps you might reconsider that i asked for a .deb package, official or not. I'm able to install roundcube from .tar.gz, but that breaks the automation that comes with the ubuntu package system and requires more attention to updates and new dependencies.

Kind regards,
