Evolution removed by partial upgrade

Yeah, I had the same problem. This is usually fixed pretty soon. I use Thunderbird myself but if you really need evolution immediately, you can downgrade evolution-common to 2.24.2 using synaptic and reinstall evolution.

Btw, do you have backports enabled? Go to "System"->"Administration"->"Software Sources"->"Updated Tab". If you have all 4 boxes checked, then you might have more dependency conflicts since you always update everything immediately. Usually, only the first 2 boxes are checked and your updates are more conservative.

Ok, the best practice is the one suggest by Bernhard, however, go in Synaptic, select evolution 2.24.2, then from the packet (? I have a localizated version, I don't know the name in english) menu and choose Force version...
Now you are able to install evolution. For me work, but I don't use exchange...

I just went ahead with this update and now I can't load evolution.

I get the Error message: "Failed to execute child process "evolution" (No such file or directory)

Does this mean it has been completely removed? And have I lost all my mail/contacts/accounts etc?
Although I have back-ups of my mail, this is still an inconvenience.

What happens now? Do I need to re-install manually?

You certainly have not lost your mail, only the executable for the evolution mail client. It is just a packaging bug in the Ubuntu repos.

evolution-common was updated to 2..24.3 but evolution needs 2.24.2. So evolution was not updated even though evolution-common was. These things happen sometimes and are usually corrected within a couple of hours. If you really need evolution immediately, see what I posted above.

May i suggest you (as a temporary solution, if you like Evolution) to try Thunderbird mail client

Thunderbird: mail/news client with RSS and integrated spam filter support
 Thunderbird is a lightweight mail/news/RSS client, based on the Mozilla suite.
 It supports different mail accounts (POP, IMAP, Gmail), has an integrated learning Spam filter, and offers easy organization of mails with tagging and virtual folders. Also, more features can be added by installing extensions.

To install Thunderbird simply search select and add it to your system using the System→Add/remove menu item

To install Thunderbird using terminal

Open a Terminal from the menu Applications → Accessories → Terminal and type:
(when the system ask you a password give your user password, you will not see nothing when you type it, then press enter)

sudo apt-get update
sudo apt-get upgrade
sudo apt-get install thunderbird

You will find Thunderbird into Applications→Internet menu

Hope this helps

Thank you for your input, Bernhard and mox.
I do have proposed repository ticked, I had enabled it to get an early fix for a couple of other problems I had, and I believe it is where the Evolution problem came from.
I have just received the missing parts of the download, and all is well in my world.
Deanc, your problem is probably resolved by now, also: if not, you may find you need to go to Synaptic and mark Evolution 2.24.3 for installation, which got me back and working.

With regard to Thunderbird, I have tried using it, but I cannot send email via smtp with it. This is somewhat of a problem when it is the protocol my ISP uses!

Thanks all, everything seems to be working now.
