I've been trying various things - not sure if they help or confuse! Firstly I should clarify one thing. For these trials Xubuntu and Lubuntu are 32 bit, the rest all 64 bit. I did not think this relevant as originally one 32bit worked, one didn't, one 64bit worked, one didn't.
I have tried to do a clean 8.04 install using the daily builds and then install the guest packages as above. The results are as follows: Kubuntu, Ubuntu and Ubuntu Mate all worked as expected. Lubuntu - couldn't get the installer to work. Xubuntu - installed OK and the tried to install the guest packages. This failed with the following message: Loading new virtualbox-guest-5.2.8 DKMS files... Building for 4.15.0-10-generic Building initial module for 4.15.0-10-generic Error! Bad return status for module build on kernel: 4.15.0-10-generic (i686) Consult /var/lib/dkms/virtualbox-guest/5.2.8/build/make.log for more information. I attach the log referred to. However, despite the error everything worked! The above does not really equate to the work I was carrying out. I am part way through installing 16.04 VMs and updating to 18.04 and will report soon. ** Attachment added: "make.log" https://bugs.launchpad.net/ubuntu/+source/virtualbox/+bug/1753430/+attachment/5072276/+files/make.log -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1753430 Title: virtualbox-guest-utils.service not starting To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/virtualbox/+bug/1753430/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
