I have Ubuntu 16.04 installed on my laptop; at random times, a task named "unattended+" uses 100% of one of the CPUs. I must be root in order to kill that process.
My questions are:
1) what is the role of "unattended+"?
2) what can I do in order to permanently stop this task?
I found this answer in another post. Apparently with 16.04 an automatic apt-get update & upgrade that is performed twice a day. https://github.com/chef/bento/issues/609
I have not addressed this problem on my install as yet, but wanted to relay this information.
dpkg and apt-get were unlocked on my install after a 5 minute delay after startup.
Could not get lock /var/lib/dpkg/lock-frontend - open (11: Resource temporarily unavailable). So I following the @waltinator's comment on this AskUbuntu question and it worked for me. Basically, you kill the process using this tool so you can use it. This is not a solution for this question but it is related to the topic and eventually it will be suitable for those who need it.
