Installing docker on AWS EC2 on an Ubuntu 20.04.6 AMI using https://get.docker.com/ is failling for me with the below error:
+ sudo -E sh -c apt-get-update -qq >/dev/null
E; Could not get lock /var/lib/apt/lists/lock. It is held by process 2023 (apt-get)
E: Unable to lock directory /var/lib/apt/lists/
Could -o DPkg::Lock::Timeout=120
be added to any apt-get
commands?
This can be used for apt version checking and adding the arg if apt version > 1.9:
APT_VERSION="$(apt --version | tr ' ' '\n' | grep -E '[0-9]+\.[0-9]+\.[0-9]+')"
APT_ARGS=""
if [ "$(echo $APT_VERSION | cut -d '.' -f 1)" -gt 1 ]; then
# apt version 2.0 or newer
APT_ARGS="-o DPkg::Lock::Timeout=120"
elif [ "$(echo $APT_VERSION | cut -d '.' -f 2)" -gt 9 ]; then
# apt version 1.10 or newer
APT_ARGS="-o DPkg::Lock::Timeout=120"
fi
echo "APT_ARGS: '$APT_ARGS'"
echo apt-get $APT_ARGS update -q
apt-get $APT_ARGS update -q
