Workaroud for apt "Could not get lock /var/lib/dpkg/lock"

apt-lock.sh

#  
# E: Could not get lock /var/lib/dpkg/lock - open (11: Resource temporarily unavailable)
# E: Unable to lock the administration directory (/var/lib/dpkg), is another process using 
# Wait for any background apt processes to finish
# There seems to be a backgroud apt process that locks /var/lib/dpkg/lock
# and causes our apt commands to fail.

while pgrep apt > /dev/null; do sleep 1; done

Another alternative is to use an bash alias:

echo "alias apt='while [ \$(fuser \"/var/lib/dpkg/lock\") ]; do echo \"Waiting on apt lock...\"; sleep 1; done; sudo apt \"\$@\"'" > ~/.bashrc

$ apt install expect
