Evolution no longer available?

Hey guys,

Does anybody know what happend to the evolution email client ?
We use it company wide, as it comes with ews plugin. But when trying to install it just now I receive this error:

Package evolution is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source
However the following packages replace it:
evolution-data-server

Package evolution-ews is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source

E: Package ā€˜evolution’ has no installation candidate
E: Package ā€˜evolution-ews’ has no installation candidate

It is really a shame, cause we need it very much. I’d be happy to get some knowledge what to do (maybe add a custom repo or things like that).
I checked availability via snap, but it is not available via snap either.

Thanks in advance

You have not told us what release you are running but evolution should be in the universe pocket of the archive (it is definitely there in 25.10):

ogra@styx:~$ grep VERSION= /etc/os-release 
VERSION="25.10 (Questing Quokka)"
ogra@styx:~$ apt policy evolution
evolution:
  Installiert:           3.56.2-4
  Installationskandidat: 3.56.2-4
  Versionstabelle:
 *** 3.56.2-4 500
        500 http://ports.ubuntu.com/ubuntu-ports questing/universe arm64 Packages
        100 /var/lib/dpkg/status
ogra@styx:~$ 

(-ews is there as well indeed)

@rastalan244 I moved your topic to Support and Help as the more appropriate place for this question.

As @ogra mentioned, we need to know which release you are on and whether or not you have universe enabled in your sources.

Thanks

Available also in Ubuntu 26.04 Resolute:

corrado@corrado-n3-rr-1101:~$ apt policy evolution
evolution:
  Installed: (none)
  Candidate: 3.56.2-7
  Version table:

Running 24.04.3. What can I do ? Any suggestions ?

I never enabled ā€œuniverseā€ before. How to do that, and what is it for ?

I think there might be something seriously wrong with my freshly installed Ubuntu, since I also encounter very strange messages when trying to install samba:

Use the GUI Software & Updates to see 5 tick boxes under Ubuntu Software
I always tick the first four and ignore source code

OK, I did that, I also have only the first 4 boxes checked. I switched my download server to: Server for United States and updated my software catalog, but the error persists.

Can not download evolution or samba.

Please install inxi with sudo apt install inxi and then run this and post the output:

inxi -r

Also post the full output of sudo apt update

When replying, highlight the text and wrap with code tags either by pressing </> in the composer or Ctrl+E on the keyboard.

Hi rubi,

inxi is also not available for installation. I guess something went wrong during my installation. I will reinstall the client and get back to this post.

inxi is also in ā€˜universe’ repository. in Software & Updates try to uncheck the 2nd box (universe) and close the GUI, then reopen and check again.
Ignore source code is ok.

I found the problem (housemade btw). I need firefox to import policies.json for my companies SSO and more other stuff. Snap firefox blocks some of the needed functionality and in order to block firefox installey by snap I added:

Package: *
Pin: release o=Ubuntu
Pin-Priority: -1

to /etc/apt/preferences.d/mozilla which lead to the aforementioned issues.

Thanks a lot to all people involved in finding the problem

That’s a great catch on the wildcard pinning:dart:. I’m curious about the Snap limitation you mentioned regarding policies.json.

Does the Snap version of Firefox completely ignore the /etc/firefox/policies directory due to sandboxing, or is there a specific path inside the Snap container where we can mount those SSO policies? I’d prefer to stick to the stock Ubuntu install if possible, but we need SSO to work.:closed_lock_with_key:

I’d be more than happy if we could get the snap firefox to work properly. The policies.json gets read, but the SSO just won’t work. Allthough all regarding things are being imported from the json file. My policies are in the default path /etc/firefox/policies/policies.json.

I use the stable snap channel for firefox (as of today version 145.0.1-1 gets pulled). and about:policies shows all desired policies are available (bookmarks, certificates, extension settings, SSO servers) but as far as I can test right now, everything works except SSO.

You should file a bug then, policies.json didnt work in the beginning either with the snap and was fixed after someone asked for it:

snap info firefox shows the correct URL for this:

ogra@styx:~$ snap info firefox|grep contact
contact:   https://support.mozilla.org/kb/file-bug-report-or-feature-request-mozilla
ogra@styx:~$

I know I should, and I would if I could (pun intended):smiley:

Error: Server Error
The server encountered a temporary error and could not complete your request.

Please try again in 30 seconds.

I try it later… Thanks
