[Bug 1549310] Re: Removing or causing lubuntu-desktop to be removed marks packages for autoremove

[Julian Andres Klode]

It's perfectly fine to remove such packages, but it will remove the
metapackage. Removing the metapackage by removing a dependency of it
will however not remove the packages it depends on, or mark them for
automatic removal.

For example, compare removing ubuntu-standard with removing lshw in
xenial: The first case marks the packages as autoremovable, the second
does not.

root at xenial:~# apt remove ubuntu-standard
Reading package lists... Done
Building dependency tree

The following packages were automatically installed and are no longer required:
  accountsservice apt-transport-https bind9-host command-not-found command-not-found-data dmidecode dnsutils friendly-recovery ftp geoip-database hdparm info iputils-tracepath irqbalance language-selector-common libaccountsservice0 libbind9-140 libdns162 libgeoip1 libisc160
  libisccc140 libisccfg140 liblwres141 libnuma1 libpcap0.8 libusb-1.0-0 lshw lsof ltrace mtr-tiny nano ntfs-3g popularity-contest powermgmt-base python3-commandnotfound python3-gdbm tcpdump telnet time usbutils
Use 'apt autoremove' to remove them.
The following packages will be REMOVED:
  ubuntu-standard
0 upgraded, 0 newly installed, 1 to remove and 70 not upgraded.
After this operation, 46.1 kB disk space will be freed.

This bug has been reported against trusty, where behavior is different:
Packages are not marked as automatically installed when installed due to
a dependency from a metapackage. It's highly likely the systems affected
where misconfigured, as the packages could not have been shown for
autoremoval if they were manually installed in the first place.
