Bug#837970: Apt simulation improvements

[Kevin Mills]

My request is more general than that. The idea is that you could chain
*any* apt commands together as a single simulation. Such as, for example, a
sequence consisting of:

add-apt-repository -y ppa:footeam/foo
apt -y update
apt -y upgrade
apt -y install foo bar

However, install with "+" or "-" does solve my immediate problem, so thank
you for that, but I still think allowing arbitrarily complex simulations
would be a good idea, assuming it's not prohibitively difficult to
implement.

You can install & remove packages at the same time. All "apt install" or
"apt remove" does is set a default for unqualified package names. If you
want to install a package append a '+' to its name, if you want it
removed append a '-'.

e.g.: apt install -s awesome apt-doc+ dpkg-dev-

This installs (or upgrades) 'awesome' and 'apt-doc' and removes
'dpkg-dev'.


Is that what you are asking for?

Bug#837970: Apt simulation improvements

[Kevin Mills]

Package: apt
Version: 1.2.12
Severity: wishlist

It should be possible to continue a simulation through several invocations
of apt. As it is, you can only do a simulation of one thing; you can't
simulate, for example, installing package X and removing package Y, only
one or the other.

Perhaps an environment variable could be added (such as APT_SIMULATE or
APT_SIMULATION), which, when defined, would cause all invocations of apt to
be part of a single simulation.
