[Resolved] Ubuntu 18.04 guest breaks after Ubuntu update, problem with 19.04
Posted: 5. Jul 2019, 21:23
I am running Ubuntu 18.04 on a Xeon platform, lots of memory and processors.
I have a further 18.04 VM on VB 6.0.4 (I am doing this as I wanted to run a package - Manager Accounting - which uses "Mono" and I don't want all that stuff on my host machine).
It was running fine up until yesterday, when the guest VM prompted me about Ubuntu updates. Forgetting the time-honoured "if it ain't broke don't fix it" rule I agreed but since then it has stopped working altogether. The guest VM starts up but seems to loop round about producing a login screen but short of actually doing it.
I tried making another 18.04 VM "from scratch" and that worked fine. Then when I put in the updates it broke again in just the same way. I suppose the answer is to be selective about which updates to install until I find the culprit
I managed to extract the accounts files from the original guest, and then tried making a 19.04 guest and got the accounts working again (phe!)
I notice, however, that if I try to install the guest additions, the install fails with the following message in /var/log/vboxadd-setup.log
I don't think that matters as I've got the accounts running and that's the only thing I want the VM for.
I'd be grateful for any advice you may have.
