Fresh 18.10 install wants to remove LVM2

[Bedlore]

Hi all, I've just installed Ubuntu Studio 18.10. After doing basic apt-get upgrades it installed the latest kernels, but now wants to remove LVM ie.


The following packages were automatically installed and are no longer required:
dmeventd libdevmapper-event1.02.1 liblvm2app2.2 liblvm2cmd2.02 libreadline5 lvm2

On an earlier install attempt I think I must of agreed to remove these and then was unable to boot and just got dropped into initramfs, with the "ALERT! /dev/ubuntu-studio-vg/root does not exist. Dropping to a shell!

Can someone tell me if this is what broke my earlier install and if so why it wants to remove it now?

Thanks

anyone?

"automatically installed" means they were installed as dependencies, but now no package depends on them so apt informs you they could be removed. That doesn't mean it's a good idea. Wisely or not, apt expects the user to decide whether to allow removal of any of these. When I see this, I usually just ignore it. I don't think Ubuntu Software or Gnome Software give this suggestion because it is confusing to users.

Note: you can prevent a package from being suggested for removal by marking it as "manually installed"

Remove lvm2 from suggestions for auto-removal:

sudo apt-mark manual lvm2
