** Description changed:
+ Update:
+ Bug #793318 has been made an alias of this bug without notifying here that it
relates to APTURL and modifying this header.
+ A similar horror story happened invisibly after clicking an APTURL link in a
Web page.
+ Please add "Affects apturl (Ubuntu)" like in that page.
+
+ Original:
software-center 5.4.1.3, Ubuntu 12.10
I downloaded steam_latest.deb from steampowered.com, saved it, double
clicked on it, and Software Center launched. It brought up the deb
information page, I clicked Install, and Software Center proceeded to
remove literally about half of the installed pacakges on my system
(about 400), including things like unity, ubuntu-desktop, and,
ironically, software-center itself. It eventually errored out (see
attached log).
Using /var/log/apt/history.log, I was able to restore the system's
packages to their previous state, but Software Center shouldn't have
allowed this to happen (whether or not the third-party .deb was actually
at fault).
NB: To correct the apt error, I did "apt-get -f install". Then, after I
apt-get installed the packages which were removed, steam was still
installed, so it wasn't a dependency error which caused the packages to
be removed. I have no idea why it actually happened.
<https://wiki.ubuntu.com/SoftwareCenter#installing>: "4. If installing
the software would involve removing ubuntu-desktop, the package should
be treated as uninstallable (just as it is with software updates). 5. If
the relevant package cannot be installed, for that reason or any other,
an error alert should appear..."
** Summary changed:
