Public bug reported:
(System: Ubuntu 14.04, up to date packages)
I noticed that unattended-upgrades spends a significant amount of time
in phases where it runs at 100% cpu. On a slower machine (core 2 t7200
2GHz) this goes on for minutes rather than seconds. This interferes with
using the machine for other tasks.
Using the --debug option to unattended-upgrades shows that the program
outputs a lot of lines like the following during these 100% cpu phases:
matching 'a'='trusty-updates' against '<Origin component:'universe'
archive:'trusty-updates' origin:'Ubuntu' label:'Ubuntu'
site:'de.archive.ubuntu.com' isTrusted:True>
>From this output I guess the operation executed is not so complicated
that it should require so much cpu power. ??
