Legacy Adobe Reader

Ubuntu

You may have to enable i386 architecture first,

dpkg --add-architecture i386
apt update

It is still possible to run the old proprietary Adobe Reader on Linux, although it is 32-bit,

wget ftp://ftp.adobe.com/pub/adobe/reader/unix/9.x/9.5.5/enu/AdbeRdr9.5.5-1_i386linux_enu.deb
dpkg -i AdbeRdr9.5.5-1_i386linux_enu.deb
apt-get -f install
apt install libcanberra-gtk-module:i386 libatk-bridge2.0-0:i386 libatk-adaptor:i386 libgail-common:i386 libxml2:i386 gtk2-engines-murrine:i386 gtk2-engines-pixbuf:i386
dpkg -L adobereader-enu | grep bin
