apt-get install with not available packages

Question

I done a script to automatically download some packages:

LIST="tcpdump nmap wifite"

apt-get --ignore-missing install $LIST

"Package wifite is not available, but is referred to by another package. This may mean that the package is missing, has been obsoleted, or is only available from another source"

I didn't find a way to force the download of all packages. apt stops from all download because there's a missing package. I can't modify the list.

Also with -f option I can't solve the problem.

using something like:

LIST="tcpdump nmap wifite"
for a in $LIST; do apt-get install $a ; done

works but it too slow

also with -y doesn't work

Answer 1

If LIST is defined outside, and you cannot modify it before, you can use sed to drop wifite before sending the list to apt-get:

LIST="tcpdump nmap wifite"
apt-get --ignore-missing install $(echo $LIST | sed -e 's/wifite//')
