Shell Provisioner - Could not get lock /var/lib/dpkg/lock

[Joanna .Leong]

Hi,

I'm running packer and have a shell provisioner executing command "apt-get update" and also tried "sudo apt-get update" and also tried sleeping before executing these commands. Regardless I keep getting the error:

Could not get lock /var/lib/dpkg/lock - open (11: Resource temporarily unavailable)

Unable to lock the administration directory (/var/lib/dpkg/)%!(PACKER_COMMA) is another process using it?

No matter how long I sleep I keep seeing this error.

correction i mean when executing any package installation like:

                "sudo apt-get install -y swig",

Guessing you are running Ubuntu and you have automatic updates on.

I've added the following to the beginning of my shell provisioning script:

sudo systemctl disable apt-daily.service # disable run when system boot

sudo systemctl disable apt-daily.timer   # disable timer run

# Disable daily apt unattended updates.

sudo echo 'APT::Periodic::Enable "0";' >> /etc/apt/apt.conf.d/10periodic

but doesn't seem to help. am i understanding this incorrectly?

Could you attach your packer template and scripts.

nevermind, got it working; needed to do:

sudo sh -c 'echo "APT::Periodic::Enable "0";" >> /etc/apt/apt.conf.d/10periodic'

Actually do I need to run a command to have packer restart the VM for my changes to take in effect?

Still I"m getting the following error:

No, or that depends in what you did. If there already are a process
holding this lock you need to shut it down gracefully.
