Unattended Upgrades fail to parse "${distro_id}:${distro_codename}-security"

[pheidrias]

Beginning with Ubuntu 13.04 Raring Ringtail, unattended-upgrades seems not to be able to parse /etc/apt/apt.conf.d/50unattended-upgrades anymore. The logfile tells:

cat /var/log/unattended-upgrades/unattended-upgrades.log
2013-05-06 14:57:05,724 INFO Pakete, die anfangs auf die schwarzen Liste standen:
2013-05-06 14:57:05,724 INFO Skript für unbeaufsichtigte Upgrades wird gestartet.
2013-05-06 14:57:05,725 INFO erlaubte Ursprünge sind: ['o=Ubuntu,a=raring-security', 'o=Ubuntu,a=raring-updates']
2013-05-06 14:57:09,114 INFO Es wurden keine Pakete gefunden, von denen ein unbeaufsichtigtes Upgrade durchgeführt werden kann.
2013-05-07 11:33:04,944 INFO Pakete, die anfangs auf die schwarzen Liste standen:
2013-05-07 11:33:04,944 INFO Skript für unbeaufsichtigte Upgrades wird gestartet.
2013-05-07 11:33:04,944 INFO erlaubte Ursprünge sind: ['o=Ubuntu,a=raring-security', 'o=Ubuntu,a=raring-updates']
2013-05-07 11:33:08,398 INFO Es wurden keine Pakete gefunden, von denen ein unbeaufsichtigtes Upgrade durchgeführt werden kann.

which means two times, that allowed sources are ['o=Ubuntu,a=raring-security', 'o=Ubuntu,a=raring-updates'].

I do suspect it is because of the automatic distribution setting in /etc/apt/apt.conf.d/50unattended-upgrades or the setting of the corresponding variables:

"${distro_id}:${distro_codename}-updates"

When this line is set manually to "Ubuntu:raring-updates", it will work.

System: Ubuntu Gnome 13.04, all up-to-date

$ lsb_release -rd

$ cat /etc/apt/apt.conf.d/50unattended-upgrades
// Automatically upgrade packages from these (origin:archive) pairs
Unattended-Upgrade::Allowed-Origins {

// "${distro_id}:${distro_codename}-backports";
};

};

Thanks for your bugrpeort.

What is the ouptut of:
$ sudo unattended-upgrades --debug
?

Status changed to 'Confirmed' because the bug affects multiple users.

Traceback (most recent call last):

    (distro_id, distro_codename) = s.split()
ValueError: need more than 0 values to unpack

It is failing to substitute `distro-id` and `distro-codename`, and so the for loop just gets: `['', '', "-security'", "-updates'", "-backports'"]`

Replacing the variable placeholders with the correct literal values fixes it as a workaround.

Note this also affects 14.04 trusty

What does the output of these lsb_release commands return?

67 DISTRO_CODENAME = subprocess.check_output(
68 ["lsb_release", "-c", "-s"], universal_newlines=True).strip()
69 DISTRO_ID = subprocess.check_output(
70 ["lsb_release", "-i", "-s"], universal_newlines=True).strip()

Actually, could you show the diff of what you had in the configuration file you modified and what you now have?

Here in Ubuntu 14.04.5 LTS it seems to install upgrades fine, even though there is "InstCount=0" in the log.
