Public bug reported:
In a fresh/clean install of Xubuntu 18.10, if an unsuspecting user runs
'apt autoremove', it will remove 'cryptsetup' and 'lvm2' making the
system non-bootable at next restart if an encrypted(LUKS+LVM) drive was
selected during the ubiquity installer wizard:
$ sudo apt update && sudo apt --auto-remove full-upgrade && cat /run/reboo*
<snip...>
The following packages will be REMOVED:
cryptsetup cryptsetup-bin cryptsetup-initramfs cryptsetup-run dmeventd
libdevmapper-event1.02.1 liblvm2app2.2 liblvm2cmd2.02 libreadline5 lvm2
<...snip>
This _will_ make the system non-bootable upon restart if LUKS+LVM are
active on main drive.
WORKAROUND:
$ sudo apt install cryptsetup lvm2
<snip...>
cryptsetup is already the newest version (2:2.0.4-2ubuntu2).
cryptsetup set to manually installed.
lvm2 is already the newest version (2.02.176-4.1ubuntu3).
lvm2 set to manually installed.
