Unfortunately, when I install the 64 bit version of the package then the 32 bit variant gets removed, and when I install the 32 bit variant then the 64 bit version gets removed. Some (slightly sanitized) console logs: $ cat /etc/issue.net Ubuntu 18.04.1 LTS $ uname -mrs Linux 4.15.0-38-generic x86_64 $ apt show libicu-dev Package: libicu-dev Version: 60.2-3ubuntu3 $ sudo apt install libicu-dev:i386 Reading package lists...

Done The following additional packages will be installed: libharfbuzz-dev:i386 libicu-le-hb-dev:i386 Suggested packages: icu-doc:i386 The following packages will be REMOVED: libharfbuzz-dev libicu-dev libicu-le-hb-dev The following NEW packages will be installed: libharfbuzz-dev:i386 libicu-dev:i386 libicu-le-hb-dev:i386 0 upgraded, 3 newly installed, 3 to remove and 0 not upgraded. Interestingly, on a Ubuntu 14.04.5 LTS (actually, on Travis CI), such a conflict does not happen. sudo apt-get install -y libicu-dev sudo apt-get install -y libicu-dev:i386 These two work just fine, the latter does not remove the former. The version there is libicu-dev 52.1-3ubuntu0.8.
