Comment # 2 on bug 1022550 from Adrien Plazas

Checking that the software is deprecated is a thing but in the end the user
won't be able to run the update, so we have two problems:
- we should be able to install the distro from the very beginning: maybe the
bug is rather that the package manager is locked by two task only reading the
repos,
- the deprecated state of the software and the danger of running outdated
software isn't stated strongly enough: saying "you have updates available" and
"you can't update your system" doesn't make security issues explicit enough.
