Installed some updates and now Liferea is not working anymore

[legolas_w]

Hi
I have just installed some updates which was including the webkit and its related libraries. Now my liferea is not working and when I run it in the console it returns the following error:

liferea: symbol lookup error: /usr/lib/libwebkit-1.0.so.2: undefined symbol: soup_content_decoder_get_type


Any idea what should I do?


Thanks

Affects me too, also software center does not work anymore due to a webkit problem.

I think you guys are using the webkit-team ppa? Seems like there's a major upgrade going on, should come back once everything's up to date I assume.

Or rather: Perhaps there was some hiccup that has installed a wrong version of libsoup2.4 and libsoup-gnome2.4. I, in any case, have fixed this by manually installing (i.e. downgrading) the two packages from the webkit-team ppa. To do so, head over to: https://launchpad.net/~webkit-team/+.../ppa/+packages and expand libsoup2.4 - 2.28.2-1~kkwkt1. Or go directly to https://launchpad.net/~webkit-team/+...-archive-extra. Then find the two deb packages libsoup-gnome2.4-1_2.28.2-1~kkwkt1 and libsoup2.4-1_2.28.2-1~kkwkt1 that correspond with your architecture (i386 or amd64), download them to a location which you can find in a terminal window, and type

sudo dpkg -i libsoup2.4-1_2.28.2-1~kkwkt1_i386.deb libsoup-gnome2.4-1_2.28.2-1~kkwkt1_i386.deb

or

sudo dpkg -i libsoup2.4-1_2.28.2-1~kkwkt1_amd64.deb libsoup-gnome2.4-1_2.28.2-1~kkwkt1_amd64.deb

(depending on your architecture). If something goes wrong, you might end up uninstalling a lot of programs, so watch out and double check before you confirm any choices.

I had the same problem and it was caused by a new version of libwebkit.

The solution is to go back to the previous version (from synaptic) or deactivate the "unofficial" repositories for Libwebkit.

Assuming that this is for beginners (like me), this issue is caused (also can be solved) with some kind of app like Ubuntu Tweak... if you have it installed, then you need to launch it and deactivate the repositories for liferea and libwebkit there.

Thanks, it worked.

You're a lifesaver. This has been bugging the hell out of me with evolution-rss the last few days and I finally have it fixed. Now I have both my evo and my Chromium fixed. Now I just have to get these two fixes blogged in hopes of helping others find them.

Ooops sorry for the mess /o\

WebkitGtk 1.1.18 is incompatible with libsoup 2.29.3, so we had to downgrade to version 2.28.2 in order to provide it.

You're AWESOME! Now i can use pino and midori again
Thanks!

[wesswei]

kudos and thanks! gotta love a quick fix. alternatively, this can be done the graphical way within synaptic...

package > force version > downgrade libsoup-gnome, then libsoup
