Title:
Unattended-Upgrades crashes with a dpkg error
Status in unattended-upgrades package in Ubuntu:
Fix Released
Status in unattended-upgrades source package in Xenial:
Fix Committed
Status in unattended-upgrades source package in Bionic:
Fix Released
Bug description:
[Impact]
* Unattended-upgrades fails upgrading packages in the middle of a dpkg/apt call due to a parallel process acquiring apt or dpkg lock while u-u is running, but u-u running apt/dpkg anyway without successfully re-acquiring the lock.
* The fix is stopping processing updates when the lock is detected to be lost.
[Test Case]
* Set up a system with packages (> 30) to be upgraded:
$ lxc launch ubuntu:b36ec647e374 uu-lock-bail
* Set up two shells to run commands in parallel
* In shell "A" run sudo apt update && sudo unattended-upgrade --dry-run --verbose --debug
* After u-u started installing the updates run the following command in shell "B":
$ while sleep 0.1; do python3 -c 'import apt, apt_pkg, time; print(apt_pkg.pkgsystem_lock()); time.sleep(2)' ; done
* With not fixed u-u observe the following exception repeated in shell "B", then True being printed when the lock is successfully stolen from u-u:
...

apt_pkg.Error: E:Could not get lock /var/lib/dpkg/lock - open (11: Resource temporarily unavailable), E:Unable to lock the administration directory (/var/lib/dpkg/), is another process using it?

Buggy u-u continues operation even after the lock is stolen.
Fixed u-u stops operation with a printout similar to the following when it detects the lock to be stolen:
...

NoneType: None
Installing the upgrades failed!

dpkg returned a error! See /var/log/unattended-upgrades/unattended-upgrades-dpkg.log for details
...
[Regression Potential]
* As a consequence of the fix unattended-upgrade stops installing
security-updates when an other dpkg frontend's parallel activity is
detected. This is intentional to prevent parallel execution of dpkg
and potentially leaving the system in an inconsistent state. The full
fix will be implemented in LP: #1781169 and changing u-u to use the
new locking mechanism, and then u-u will never lose the lock.
[Other Info]
I believe parallel dpkg calls cause many breakages reported against
u-u and other packages listing breaking maintainer scripts.
