Bien cordialement,

Ch.Meessen

The problem is still not solved.

I could fix the problem with the following change to the code.

In file /usr/bin/unattended-upgrade at line 814 I changed

        subject = _("unattended-upgrades result for '%s': '%s'") % (
            host(), res)

into

        tmp = _("unattended-upgrades result for '%s': '%s'")
        subject = tmp % (host(), res)

The error message then disappear.

Note that the same problem

The problem only shows up when the following line has been uncommented in the file /etc/apt/apt.conf.d/50unattended-upgrades

Unattended-Upgrade::Mail "root";

Unfortunately, the suggested fix doesn't work.

The reported error is fixed by changing the line 814 In file /usr/bin/unattended-upgrade

        subject = _("unattended-upgrades result for '%s': '%s'") % (
            host(), res)

into

        subject = _("unattended-upgrades result for '{}': '{}'").format(
            host(), res)

Unfortunately the % formating is used in many places and changing this line doesn't definitely fix the problem with unattended-updates.

Worse. Every time unattended-upgrades tries to upgrade packages I end up with a broken package. I need to use synaptic to fix the broken package. Not sure if it is properly fixed.

Could someone please fix this issue ? This means people don't get their packages automatically upgraded. Doing it manually fails because of the broken package.

Thanks for the bugreport and sorry for the slow reply. I was able to reproduce the issues and uploaded a fix to wily-proposed. The debdiff is attached.

It affects systems that use utf-8 chars in the output. So system default English is fine, most other systems are not.

Hello,

the problem is solved for me by using the proposed version of unattended-upgrades.
Thank you Brian for the detailed explanation for installing proposed packages.

From my point of you, the package is ready for release.

Thank you Michael.

This bug was fixed in the package unattended-upgrades - 0.86.2ubuntu1.1
