Troubleshooting

Could not get lock /var/lib/dpkg/lock-frontend

root@openstack-compute02:/home/kevin# sudo apt-get install python3-dev libffi-dev libssl-dev -y
E: Could not get lock /var/lib/dpkg/lock-frontend. It is held by process 10748 (unattended-upgr)
N: Be aware that removing the lock file is not a solution and may break your system.
E: Unable to acquire the dpkg frontend lock (/var/lib/dpkg/lock-frontend), is another process using it?

Solution

root@openstack-compute02:/home/kevin# vi /etc/apt/apt.conf.d/20auto-upgrades
APT::Periodic::Update-Package-Lists "0";   # change from 1 to 0
APT::Periodic::Unattended-Upgrade "0";
