What packages are safe to remove (purge)?

[int_ua]

I've deleted all games except chess (will add package names on request) and

osso-systemui-splashscreen
cherry

without losing any critical functionality.
Who tried any other package? Unsuccessfull strories?

[Russe89]

Here is a list of all apps i remove when i flash my N900:

sudo apt-get remove
hildon-theme-beta
osso-chess-ui
gnuchess osso-graphics-game-chess
osso-lmarbles osso-graphics-game-lmarbles
osso-sounds-game-chess
maemoblocks
ap-installer amazon-installer foreca-installer facebook-installer skype-installer dtg-installer
tutorial-home-applet
osso-tutorial-l10n-engb
osso-tutorial-l10n-ptpt
osso-tutorial-l10n-frca
osso-tutorial-l10n-nlnl
osso-tutorial-l10n-cscz
osso-tutorial-l10n-itit
osso-tutorial-l10n-eses
osso-tutorial-l10n-svse
osso-tutorial-l10n-frfr
osso-tutorial-l10n-dede
osso-tutorial-l10n-fifi
osso-tutorial-l10n-nono
osso-tutorial-l10n-esmx
osso-tutorial-l10n-enus
osso-tutorial-l10n-ruru
osso-tutorial-l10n-mr0
osso-tutorial-l10n-plpl

So its just the games, the secondary theme and the whole tutorial and the installer apps, but i don't need them.

[reinob]

but if I try removing e.g. cherry, then mp-fremantle-pr is removed, thus marking a number of (critical?) packages as auto-removeable!

do you install/reinstall those packages manually? or have you manipulated the mp-fremantle-pr metapackage to fix the dependencies?

at the moment saying that you can delete some of those packages "without losing any critical functionality" seems a bit of a risky statement.

I would also be interested in removing a whole bunch of things I don't need, but perhaps any of you who have actually done that could explain more in detail which steps you've followed?

Thanks.

It was a long time ago when I deleted the games. I think I just marked them as manually-installed with apt-get install. Maybe I didn't notice and deleted something useful, please add the packages which are marked for auto-removal.

@int_ua,

Sorry for the late reply.

Use 'apt-get autoremove' to remove them.
The following packages will be REMOVED:
   cherry* (0.25-1+0m5)
   mp-fremantle-generic-pr* (21.2011.38-1)
0 upgraded, 0 newly installed, 2 to remove and 20 not upgraded.
Purg mp-fremantle-generic-pr [21.2011.38-1]
Purg cherry [0.25-1+0m5]

I suppose I could first mark (some of) those packages as manually installed so that they are not auto-remove'd, but I still find this dependency chaos very annoying.

but I still find this dependency chaos very annoying.

Just reflashed device. Updated to the PR-1.3.1 with HAM
And then continued with apt-get -s purge cherry (or apt-get remove --purge cherry) and it will only uninstall cherry and mp-fremantle-generic-pr (not hundreds of packages)

Who tried any other package?

I started to fill this wikipage with my experiments:
http://wiki.maemo.org/Fremantle_closed_packages

If somebody want join filling, I have four steps to gather basic information.

#description
apt-cache show osso-systemui-splashscreen
#Provides files:
dpkg -L osso-systemui-splashscreen
#Current version
apt-cache policy osso-systemui-splashscree
#Reverse dependencies
apt-cache showpkg osso-systemui-splashscreen

#Remove (on device which can be reflashed)
apt-get remove --purge osso-systemui-splashscreen

And then I have explicitly state what happens when removed. I have tried to be verbose and comment every aspect.

I have found it is sometimes hard to say what is critical functionality. I have never used ActiveSync, so removing ActiveSync is not losing critical functionality? I rarely use bluetooth, so it is then not critical functionality? For sure when device will not start anymore = critical.

A few days ago I decided to remove mp-fremantle-generic-pr. That was the only package that was removed, but then the list of packages I posted above are marked as being auto removeable.

I manually installed some of them (the ones that sounded like I could need them) and then did auto remove of the rest. Everything's OK for now (I didn't dare reboot yet..)

I'm going through a list of all packages in my N900 and marking the ones I would like to remove (particularly all l10n packages for language/country combinations that I will never need), but I'm still in the "preparation phase" (just editing my list on the computer).

It will take time until I actually do that, but then I'll post my results (if at all relevant). I have never flashed my N900.. and would like to keep it that way

[reinob]

I have also removed qtm-maemo-metapackage and its dependencies (libqtm-*), as no other package seems to depend on that (YMMV).

You can check it here:
http://maemo.org/packages/package_in...age/1.3-2+0m5/

[reinob]

Soo.. I just shutdown and turned on my N900 again. No problems at all.

I marked the following as manually installed (because of mp-fremantle-generic-pr):

	libtpsession (0.1-6+0m5)
	rtcom-accounts-plugin-facebook (4.140-1+0m5)
	libqt4-declarative (4.7.0~git20100909-0maemo1+0m5)
	rtcom-skype-emoticons-theme (0.0.7-2+0m5)
	rtcom-accounts-voip-support (4.140-1+0m5)
	n900-fmrx-enabler (1.5-4+0m5)
	libconninet0 (0.40+0m5)
	dsme-thermalobject-surface (0.0.1+0m5)
	modest-home-applet (0.0.4-5+0m5)
	libconnsettings0 (0.23+0m5)
	microb-geolocation (1.1.5-6+0m5)
	libqt4-translations (4.7.0~git20100909-0maemo1+0m5)
	libtelepathy-qt4-0 (0.2.0-2maemo7+0m5)

and then purge-removed the following:

mp-fremantle-generic-pr
libqtm-*
maemo-optify-runonce
cherry
sharing-service-flickr
sharing-service-ovi
chinese-font
google-search-widget
tutorial-home-applet
osso-tutorial*
testserver
{ap,amazon,foreca,facebook,skype,dtg}-installer
osso-lmarbles, osso-graphics-game-lmarbles
osso-mahjon, osso-graphics-game-mahjong, osso-sounds-game-mahjong
maemoblocks
osso-rss-feed-reader*
qtm-modest-plugin

So far so good.

Next in line are *-l10n-* (except -mr0 and -enus, -dede)
as well as ezitext-* (I don't even use the VKB at all).

Next-next in line are:
osso-systemui-splashscreen (need to make sure first)
hildon-welcome (same thing)
kernel-modules (from stock kernel, I only use kp50 now).
