Something is incorrectly invoking update-manager with Python 2, but it's been ported to Python 3. Do you know how update-manager was started here? Was it from some other program, or manually, or what?

[Barry Warsaw (barry)]

Just to complete the circle, this probably happens because the UpdateManager module is now only installed in the Python 3 sys.path, so when invoked with Python 2, the module isn't found.

Does it make sense to crash with a more useful message? E.g. we could put a sys.version test at the top of update-manager and complain loudly if it wasn't invoked with Python 3. OTOH, maybe this is good enough.

Yes, the bug is not in Update Manager, but in whatever is invoking u-m with the Python 2 command line.

ele não deixa atualizar o sistema

This happened to me just now as well, right after an dist-upgrade that also seems to have change the updater's config file.

toda vez que uso "software atualizado" o bug trava tudo.

ataca toda vez que tento atualizar.

When I try to run Software Updater from the Software Up To Date menu item (under the gear wheel), I get no errors but the Software Updater just doesn't open. When I tried to run it from the command line (update-manager) I get the error message shown. The problem persists after upgrading the 3.5.0-3-generic kernel to 3.5.0-4-generic.

[Stephen Cradock (s-cradock)]

I get the same bug; I can confirm that issuing the command "/usr/bin/python3 /usr/bin/update-manager" in a terminal starts UpdateManager without error.

[Stephen Cradock (s-cradock)]

The file /usr/bin/update-manager is a text file whose first line reads "#!/usr/bin/python"

Could the fix be as simple as appending the character 3 to this string?

Yes - that fixes it.

[Karma Dorje (taaroa)]

confirm this.
this (fix shebang) fixes it. as workaround or complete fix.

[mscout2004 (mscout2004)]

Stephen is right just adding the 3 to the end of the first line in that file corrects the problem with the update-manager crashing.

[mscout2004 (mscout2004)]

Adding "3" to the end of the first line of code does seem to be a complete fix to this problem.

[Emanuele Sottocorno (sotema)]

For me too adding the 3 fixes the problem

This happens to me when starting update manager from system menu (top right corner of Unity's menu bar).

[Sebastien Bacher (seb128)]

the recent comments are a recent regression and should probably be tracked in a new bug

[Sebastien Bacher (seb128)]

the new issue is bug #1023474 and a fix just got uploaded

[col reilly (lupinehorror)]

chose 'show updates' from the task bar icon (xubuntu) and crash happened. when i selected 'install updates' things proceeded correctly.

[Dmitry Shachnev (mitya57)]

It seems that the error is gone with the fix for bug 1023474.
