I think you missed the point of this bug report and its grave status for
"unattended-upgrades".
This bug happens even when there is *no* "intermediate" update available in the
Ubuntu repository (allowed-origin).
When there is an *UPDATE AVAILABLE IN AN EXTERNAL REPOSITORY*
(not-allowed-origin),
"unattended-upgrades" installs the package from the Ubuntu repository, which
hasn't even changed (!)
Example:
ubuntu: 1:1.0
now: 0:123.0
ppa: 0:123.0 (apt-pinned to 1000)
Update available *IN THE EXTERNAL REPOSITORY*:
ubuntu: 1:1.0
now: 0:123.0
ppa: 0:124.0 (apt-pinned to 1000)
"unattended-upgrades" stupidly installs 1:1.0 (WTF?!):
ubuntu: 1:1.0
now: 1:1.0
ppa: 0:124.0 (apt-pinned to 1000)
And then a manual "apt-get upgrade" (properly) installs 0:124.0:
ubuntu: 1:1.0
now: 0:124.0
ppa: 0:124.0 (apt-pinned to 1000)
> but the "workaround" is the right solution for this issue.
(workaround = pinning Ubuntu repository to 1/-1 for all external packages)
Wrong.
You may add the entire Debian repository (which will be not-allowed-origin),
and now you have to pin every package (and dependency!) installed from Debian
*by name*
in order for "unattended-upgrades" not to mess with them.
This "solution" would be ridiculous.
> particularly odd case
No odd case here: there was *no* update available in the Ubuntu repository in
this case.
It's "unattended-upgrades" behavior that is odd and completely broken.
> it's very hard to implement
This doesn't justify keeping a grave bug in "unattended-upgrades"
behavior.
And it shouldn't be that hard:
1. Get the list of packages+version+origin that can be updated no matter of the
allowed-origin state, no messing with apt-pinning.
2. Upgrade only the packages from this list that have origins that are allowed.
To sum up: "unattended-upgrades" completely breaks APT pinning (meant
mostly for external repositories) and selects completely wrong versions
for installation candidates. Period.
