I have this in my .bash_aliases and call it before running apt-get install or apt-get upgrade Example: alias apt-install='apt-update; apt-get install' alias apt-upgrade='apt-update; apt-get upgrade' function apt-update () { if [[ $(expr $(date +%s) - $(stat -c %X /var/lib/apt/periodic/update-success-stamp)) -gt 86400 ]]; then sudo apt-get update else echo apt is up to date fi }

# AllInOne: Update what packages are available, upgrade to new versions, remove unneeded packages # (some are no longer needed, replaced by the ones from ap upgrade), check for dependencies # and clean local cached packages (saved on disk but not installed?,some are needed? [this only cleans unneeded unlike ap clean]). # aliases (copy into ~/.bashrc file): alias a='alias' a ap='apt-get' a r='ap autoremove -y' a up='ap update' a u='up && ap upgrade -y --show-progress && r && ap check && ap autoclean' # && means "and run if the previous succeeded", you can change it to ; to "run even if previous failed". I'm not sure if ap check should be before or after ap upgrade -y, you can also change the alias names. # To expand aliases in bash use ctrl alt e or see this ow.ly/zBKHs # For more useful aliases go to ow.ly/zBMOx

If you are an unlucky soul behind a corporate firewall you will likely find that downloading gpg keys is blocked. This is because the hkp protocol uses port 11371 by default to transfer the key. By adding "hkp://" to the beginning of the hostname and ":80" to the end you are asking gpg to try using port 80 to connect (less likely to be blocked by a firewall). This relies on the remote server answering to requests over port 80. Show Sample Output
