FWIW I only run

  tool update

$ cat /usr/local/bin/tool

        color="-o APT::Color=0"
        keepp="-o APT::Keep-Downloaded-Packages=1 "
        quiet=""
        case $1 in
          -q*|--quiet)
            quiet="-qq ";;
        esac
        case $1 in
# snip
            sudo apt update $quiet$color && \
            sudo apt-file update && \
            sudo auto-apt updatedb && \
            sudo auto-apt update-local && \
            sudo apt full-upgrade $keepp$color && \
            sudo apt autoremove $color;;
