Hi All, Just tried to upgrade my simple LAMP box from Wheezy to Jessie, but this error prevents whole process
root@xxx:~# apt-get --download-only dist-upgrade Reading package lists... Done Building dependency tree Reading state information... Done Calculating upgrade... Failed The following packages have unmet dependencies: udev : Breaks: plymouth (< 0.9.0-7) but 0.8.5.1-5 is to be installed E: Error, pkgProblemResolver::Resolve generated breaks, this may be caused by held packages. I did exactly the same procedure few days ago and all went well. It looks that udev version: 215-5+b1 introduced above problem. My first thought was to upgrade plymouth to 0.9.0-7 but it fails with following error ... Setting up plymouth (0.9.0-7) ... Installing new version of config file /etc/init.d/plymouth-log ...

Maybe that should be reported as a bug ? Thanks.
