Even use apt-get update, this cannot work, when in create this bug. I found the solution to install the package with aptitude which proposed to downgrade the openssh-client package.
But, now, the new version is avalaible : openssh-server 1:5.3p1-3ubuntu5. So i think you can close the bug. Even this isn't use, this is the results of asked commands openssh-server: Installé : 1:5.3p1-3ubuntu5 Candidat : 1:5.3p1-3ubuntu5 Table de version : *** 1:5.3p1-3ubuntu5 0 500 http://fr.archive.ubuntu.com/ubuntu/ lucid-updates/main Packages 100 /var/lib/dpkg/status 1:5.3p1-3ubuntu3 0 500 http://fr.archive.ubuntu.com/ubuntu/ lucid/main Packages openssh-client: Installé : 1:5.3p1-3ubuntu5 Candidat : 1:5.3p1-3ubuntu5 Table de version : *** 1:5.3p1-3ubuntu5 0 500 http://fr.archive.ubuntu.com/ubuntu/ lucid-updates/main Packages 100 /var/lib/dpkg/status 1:5.3p1-3ubuntu3 0 500 http://fr.archive.ubuntu.com/ubuntu/ lucid/main Packages ** Changed in: openssh (Ubuntu) Status: Incomplete => Opinion -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to openssh in ubuntu. https://bugs.launchpad.net/bugs/721207 Title: Dependance problem install openssh server -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs
