MUSTFIX:
--------
* debconf gnome dosn't work (can't connect to the session)
[ should be fixed with the bugfix on gksu ]
* display a message that all applications should be closed for the
dist-upgrade (and that strange things like a crashing panel can
happen)
[done in current dialog]
* sources.list edit needs to add valid sources if all other sources
are commented out
(or for sources that can't be identified and rewrite ask the user
what to do by just s/breezy/dapper/g?)
[Done]
* inform about commented out sources
[Done]
* fix "no activity for 120s warning" being repeated every sec in the logs
[Done]
* [fabbio]: we probably don't want to remove stuff that moved from main
to universe (if the user has only main enabled this is considered
obsolete). It would also be nice inform about packages that went from
main->universe. We could ship a list of demotions.
* [kamion]: we could use debconf-frontend=dialog and then detect the ansi
seqence that clear the screen and open the terminal then
-> trouble: vte does not give me the raw codes but only the
text (as \n\n\n\n\n... for cls)
* add "add cdrom" to the "Do upgrade?" screen? And recalc the download
size again then :) ?
* set bigger timeout than 120s?
* make the sources.list rewrite even more robust (see launchpad #41023)
breezy->dapper
--------------
- gnome-icon-theme changes a lot, icons move from hicolor to gnome.
this might have caused a specatular crash during a upgrade
hoary->breezy
-------------
- stop gnome-volume-manager before the hoary->breezy upgrade
(it will crash otherwise)
- send a "\n" on the libc6 question on hoary->breezy
general
-------
- CDROM upgrades !!!
- whitelist removal (pattern? e.g. c102 -> c2a etc)?
- check authentication and don't upgrade anything that is not
authenticated (maybe just comment unauthenticated stuff out?)
Robustness:
-----------
- automatically comment out entires in the sources.list that fail to
fetch.
Trouble: apt doesn't provide a method to map from a line in th
sources.list to the indexFile and python-apt dosn't proivde a way to
get all the metaIndexes in sources.list, nor a way to get the
pkgIndexFiles from the metaIndexes (metaIndex is not available in
python-apt at all)
What we could do is to write DistUpgradeCache.update(), check the
DescURI for each failed item and guess from it what sources.list
line failed (e.g. uri.endswith("Sources{.bz2|.gz") -> deb-src, get
base-uri, find 'dists' in uri etc)
- don't stop if a single pkg fails to upgrade:
- the problem here is apt, in apt-pkg/deb/dpkgpm.cc it will stop if
dpkg returns a non-zero exit code. The problem with this is of course
that this may happen in the middle of the upgrade, leaving half the
packages unpacked but not configured or loads of packages unconfigured.
One possible solution is to not stop in apt but try to continue as long
as possible. The problem here is that e.g. if libnoitfy0 explodes and
evolution, update-notifer depend on it, continuing means to evo and u-n
can't be upgraded and dpkg explodes on them too. This is not more worse
than what we have right now I guess.
