also... you could put a check in the script to look at the size of the database.
It should be possible to check any number of things from this script.

Hi,
Nio e-mailed me about this recently.
I have one idea, that might work.
a postintpostint script is being described... so the only real hacky
workaround I can think of is to create a script.
This script can check for internet and wait until apt is finished(or
wait 5 minutes). Then it can updat
OK, let us call it "won't fix" now.
I would suggest that Jörn and I discuss the issue privately and maybe
agree about the details and after that ask Julien (gilir) to help us add
such a file when creating the alternate iso file. I guess there is a set
of scripts (similar to (but more advanced than
There's no reason we couldn't include this in updates. If you seriously
have a plan to make this happen, Nio, please assign this to yourself.
Otherwise, I'm going to call this Won't Fix.

If someone finds a way to create that file with the alternate iso, I'm
willing to sponsor a patch for LSC.

I'm not sure there is time to do it today for 15.04, but I think it
would be possible given more time. Such a 'flag file' and the logic to
use it can be included in the LSC package, and it would start working

Hi Nio,
1. it is way faster, really a big difference. USC was made a bit faster, but
it's still not comparable to LSC.

issue.

trick. It is in postinst but clearly locked apt makes for a problem. Is

What about Muon (Kubuntu)? I don't know if Kylin's Software Center is

Could we add a conditional to check to see if we're using debian-

Shipping the database one the iso means 80 MB more, not sure how good

Sigh, another reason I don't love the alternate image.
I think it would be wise to include all packages in the database and

No, it is clearly a design flaw. While the DB is being generated, it
drops every package without installation candidate. On the alternate
install, there are no informations about the avaible packages so
everything is dropped, if it isn't installed. That is why DB is that
small, it should be around
…or perhaps, is this an issue with debian-installer since it only

Given all this informations, it seems that the DB is generated too early
(when APT hasn't updated it cache yet) or without internet connection at

issue.
I would even bet, this issue is present on old alternates, too.
