So now, I have got a .deb file from https://releases.jfrog.io/artifactory/artifactory-debs/pool/jfrog-artifactory-oss/
I voluntarily take the lastest .deb minus one (for me now 7.104.13 instead of 7.104.14)
/opt/jfrog/artifactory/app/bin/artifactoryctl stop
dpkg -i jfrog-artifactory-oss-7.104.13.deb
it replaces 7.98.13 by 7.104.13
/opt/jfrog/artifactory/app/bin/artifactoryctl start
And i have the new version running.
BUT I am still unable to update to the latest version using apt update. There seems to be no repository for Bookworm if I believe apt (even if I see one on the Jfrog website).
How could I update more easily ?
