Hi! I'm having a problem upgrading an existing 4.4 installation to 5.0. - The machine is a x86_64 architecture - I'm upgrading from a DVD - I've used the same DVD to sucessfully upgrade another machine (therefor I'm pretty sure that it is OK) - The error occurs on both DVD-drives on the machine (therefor I think its not a problem with a particular DVD-drive) I'm clicking through the upgrade dialogs. Then the machine prepares to install the packages. At the end of this a dialog-box appears: Error running transaction There was an error running your transaction for the following reason(s): Apart from that text there is only a Reboot-button (no explanation) On the other virtual terminals there is nothing unusual (last line in Ctrl+Alt+F3 is "Preparing to install packages") The /root/upgrade.log is empty. My guess is that there might be some packages that offend the installer (there are some non-standard packages on the machine, don't shout at me: I know that's bad (amongst them a 32-bit firefox)). Is there a way to find out which packages are the bad ones? Any tips would be most welcome. Thanks PS: What I'm trying right now is removing the worst offenders and retry the upgrade procedure in text mode.
