Hi Markus, thank you for your reply. I've installed a fresh Debian Stretch and I think I know why I had such a problem. I believe it's a dependency problem, but I let you decide, if this is the case. We're always installing the packages "pacemaker" and "crmsh" on our systems. As you know, the latter one has a dependency to the "pacemaker-cli-utils" package:
$ apt-cache depends pacemaker | grep pacemaker-cli-utils Breaks: pacemaker-cli-utils Recommends: pacemaker-cli-utils Replaces: pacemaker-cli-utils $ apt-cache depends crmsh | grep pacemaker-cli-utils Depends: pacemaker-cli-utils This is the reason why we have the "pacemaker-cli-utils" package on our systems. We didn't install it manually, it was installed due to the dependency. So far so good. After you provided the new package of pacemaker, I did the following: $ apt install pacemaker crmsh This will update the two packages to the new version, but it will not update the package "pacemaker-cli-utils", but as you pointed out correctly, the new version of this package is needed as well. It could be, that I'm not fully understand the dependencies of packages, but in my humble opinion: If the "crmsh" package needs the "pacemaker-cli-utils" package and installs it in the first place due to the dependency, it should also update the dependency package if it needs the newer version. Why not use "apt upgrade" and update all packages? We have some company policies with an approval process to update our systems including a maintenance window. I didn't want to just update all non related packages to "hotfix" the pacemaker problem. Why not "apt install pacemaker crmsh pacemaker-cli-utils"? This didn't come to my mind in the first place, because we do not install the pacemaker-cli-utils package as mentioned before. But this fixes the issue of course.
