Title:
apt-get install REMOVES packages without replacing them and with
barely any warning
Status in apt package in Ubuntu:
Invalid
Bug description:
I did:
$ sudo apt-get install ettercap-common
(by the way I don't even know what that is, but it is one of a few
packages being "held back" by apt and that prevents me from upgrading
from 18.04 to 20.04. Since apt itself doesn't give me a clue what to
do and there doesn't seem to be a guide anywhere, I'm blindly trying
stuff)
and I got:
Reading package lists... Done
Building dependency tree
Reading state information... Done
The following packages were automatically installed and are no longer
required:
[...]
Use 'sudo apt autoremove' to remove them.
The following additional packages will be installed:
ettercap-graphical libcurl4
The following packages will be REMOVED:
libcurl3 php7.2-curl virtualbox-6.0 <<<<< NOTE THIS !!!!!!!!!!
The following NEW packages will be installed:
libcurl4
The following packages will be upgraded:
ettercap-common ettercap-graphical
2 upgraded, 1 newly installed, 3 to remove and 6 not upgraded.
I didn't notice the part that said that some apparently unrelated packages,
one of which I had installed manually (Virtual Box) would be removed.
Technically it asked me for confirmation, but it was in the middle of
a bunch of other much more trivial stuff, and you can't just put
"REMOVE" in caps and expect me to notice it.
If an INSTALL command is going to UNINSTALL something that huge (not
just a library that had been installed automatically and is no longer
required, but an entire application that I installed manually!), you
must give a very specific and explicit prompt (defaulting to No rather
than Yes) with a gigantic warning, something like:
***********************************************************
* !!!!!!!! A T T E N T I O N !!!!!!!! *
* *
* If you proceed, the following packages will be REMOVED *
* *
* and NO SUITABLE REPLACEMENT will be installed *
* *
***********************************************************
Are you REALLY sure you wish to continue? [y/N]
(possibly red and blinking)
NEVER before, in my entire life, have I ever seen an instance where "apt-get
INSTALL" would REMOVE packages without at the same time replacing them with
some more recent version or something, and even that is rare.
I can't see a reason why the installation of a package would require
the removal of another, unless it is to replace it with something that
superseeds it.
Usually the list of stuff, that you're asked confirmation for when running
"apt-get install", only includes stuff to be installed, upgraded and left
untouched, never removed, so I'm used to responding "Yes" almost automatically.
Here's the rest of the output
