I want to install arm64 libraries in my ubuntu bionic so I can link using cmake for cross compiling. Here's what I'm doing, based on https://askubuntu.com/a/994650/613425

dpkg --add-architecture arm64\
&& echo "deb [arch=arm64] http://ports.ubuntu.com/ bionic main restricted\n\
deb [arch=arm64] http://ports.ubuntu.com/ bionic-updates main restricted\n\
deb [arch=arm64] http://ports.ubuntu.com/ bionic universe\n\
deb [arch=arm64] http://ports.ubuntu.com/ bionic-updates universe\n\
deb [arch=arm64] http://ports.ubuntu.com/ bionic multiverse\n\
deb [arch=arm64] http://ports.ubuntu.com/ bionic-updates multiverse\n\
deb [arch=arm64] http://ports.ubuntu.com/ bionic-backports main restricted universe multiverse"\
| tee -a /etc/apt/sources.list

gives me

In /etc/apt/sources.list you have to add [arch=amd64] in front of the amd64 sources (Or your host's system arch if it's something else) Example:

deb [arch=amd64] http://de2.archive.ubuntu.com/ubuntu/ bionic main restricted
deb-src [arch=amd64] http://de.archive.ubuntu.com/ubuntu/ bionic main restricted
