[ANSWER REGARDING COMMENT # 05 FROM LocutusOfBorg] Hi Locutus
Yes, I was able to install v.5.1.34 and from the deb packages from Oracle's website when I migrated to Mint 17 and later to Mint 18.1. Although the VirtualBox program itself installs and loads alright and I could build a new VM under it, the Virtual Machines I already got simply refuses to starts under any VirtualBox v.5.1 or v.5.2 version (I built these VM's at the time I was still using Linux Mint 13 Xfce some four years ago!). Since I invested a lot of money and specially a lot of time building these VM's, rebuilding them from scratch on VirtualBox v.5.1 or v.5.2 is something I am not contemplating to do right now. I may be forced to rebuild them some years in the future when I migrate to a newer Mint version down the road if the v.5.0 version does not work under that future Mint version (although I think that unlikely). Thanks anyway for your concern: it is deeply appreciated. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1758946 Title: virtualbox-guest-utils update caused Synaptic to stop working To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/virtualbox/+bug/1758946/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
