For Adobe Acrobat Reader DC (running with Wine) You can, however, get a newer version using the process below (this installs a Windows version of Adobe Reader on Ubuntu). This is, of course, a very outdated version of Adobe Reader, but this is not Ubuntu's fault, Adobe haven't updated the Linux client of Adobe Reader. If it still doesn't work, try sudo apt install libxml2:i386. If you can't find/run Adobe Reader, you will need to run sudo apt -f install to resolve dependencies. There's less of a chance you'll ruin your system if you get it this way.

For Adobe Reader 9.5.5 (running natively without Wine)ĭon't add the Ubuntu 12.04 Partner repository, you're not really supposed to add repositories from previous Ubuntu versions! Get the Deb from here ( source - it's also linked in the question), no it won't be automatically updated but since it's no longer supported (and Ubuntu can't patch security vulnerabilities for it in Ubuntu 12.04 anyway because it's proprietary) that doesn't matter.
