Bug#119509: apt: multiple incompatible invocations of apt should not be allowed

[Jeff Sheinberg <jeffsh@erols.com>]

Package: apt
Version: 0.5.4
Severity: normal

Hi,

I invoked "dselect", using the apt method of course, and I then
selected "Install".

After the download phase of the "Install" had completed, but
before the remaining phases of the "Install" had completed, I
edited the "sources.list" file in another "xterm" window, and then
invoked "apt-get update" in that same other "xterm" window.

At the end of the original "Install" phase, I got these error
messages from "apt",

    Del doc-linux-text 2001.09-1 [6798kB]

    W: You may want to run apt-get update to correct these problems

So, it seems to me that "apt" should have prevented me from
running the "apt-get update" in one window while the "Install"
was active in another window.

Thanks,
