The following packages have unmet dependencies:
  libsdl1.2debian-alsa: Conflicts: libsdl1.2debian-pulseaudio but 1.2.13-5 is to be installed.
  epiphany-browser: Conflicts: epiphany-gecko but 2.26.3-2 is installed and it is kept back.
  libsdl1.2debian-pulseaudio: Conflicts: libsdl1.2debian-alsa but 1.2.13-5 is installed.
  epiphany-gecko: Depends: epiphany-browser-data (< 2.27) but 2.29.3-1 is to be installed.

I'm not sure what to do--uninstall Epiphany? Please advise.

I'm personally leaving Epiphany un-upgraded until their are no conflicts. Which should be when the 'gnome' meta-package gets upgraded to 2.28 after the last bits of 2.28 are migrated to Testing.

So, how to upgrade the whole system excluding one particular application since safe-upgrade does not do that? Will

Code: Select all

aptitude hold epiphany

do the trick? But safe-upgrade is supposed to always use the safe-resolver algorithm, according to aptitude manual.

Also there are conflicts between libsdl1.2debian-alsa and libsdl1.2debian-pulseaudio.

Squeeze was installed from a weekly-build.

Show the rest of what aptitude is proposing to do (it's recommended solution). (In other words show the ENTIRE output). Also run it with the -D option. You can run the following as a normal user (nothing will actually get upgraded no matter what you answer):

Code: Select all

aptitude -sD safe-upgrade

I use Synaptics and manually select upgradable packages each day. I'm not familiar with aptitude or apt-get.

Hello bugsbunny, that WAS the entire output. Still here is what I got after running -sD safe-upgrade

Use apt-cache show <packagename> and apt-cache depends <packagename> to see what packages you need, which ones are conflicting, & etc..

For example:

Code: Select all

$ apt-cache show epiphany-gecko

You may then decide to remove certain packages, thus allowing installation of others.

I know what aptitude asks during the upgrade process and I was expecting it. But all it did was going back to my prompt just after mentioning the conflicts. I didn't paste up to the prompt line, and here it is:

BTW, Epiphany conflict got resolved automatically after I installed flashplugin-nonfree, sun-java6-jre. I don't know which one resolved the problem.

[bluesdog]

Of course you are updating local apt cache first with

Code: Select all

aptitude update

To check your sources list, please post output of

Code: Select all

cat /etc/apt/sources.list

and to see if anything is being held back:

Code: Select all

aptitude search ~ahold

and to do a sanity check on dpkg

Code: Select all

dpkg -C

and to see specific information on the packages which seem in conflict

Code: Select all

apt-cache policy libsdl1.2esd

Code: Select all

apt-cache policy libsdl1.2debian-esd

and

Code: Select all

apt-cache policy libsdl1.2debian-alsa

[jheaton5]

I had the same dependency issues. I apparently updated after the break in squeeze. Today I did

Code: Select all

# aptitude --full-resolver full-upgrade

@ 100 files were removed @100 new files were added and @100 files upgraded. The system is now restored to where it should be.

[bluesdog]

jheaton5, that's good and useful information.

I've been running Sid/Experimental, and doing full-upgrades so long I'd forgotten about the resolver switch for aptitude

safe-upgrade is for wimps!

[TristanDee]

@ bluesdog and jheaton5: I've been currently away from my home PC. I'll definitely try your suggestions, especially that of jheaton5 since you say you had similar dependency conflict situation, when I get back home tonight. Meantime, thanks for all your cooperation.

I'll get back to you guys with updates.
