How do I install Adobe Acrobat in Ubuntu 16.04?

I followed the tips below on Kubuntu 16.04 64 bit:

sudo add-apt-repository "deb http://archive.canonical.com/ precise partner"
sudo apt-get update
sudo apt install adobereader-enu

After properly installed Adobe Reader, don’t forget to remove the Canonical Partners repository for Precise:

sudo add-apt-repository -r "deb http://archive.canonical.com/ precise partner"
sudo apt update

For Adobe Reader 9.5.5 (running natively without Wine)

Don'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. There's less of a chance you'll ruin your system if you get it this way.

If you can't find/run Adobe Reader, you will need to run sudo apt -f install to resolve dependencies. If it still doesn't work, try sudo apt install libxml2:i386.

This is, of course, a very outdated version of Adobe Reader, but this is not Ubuntu's fault, Adobe haven't updated the Linux client of Adobe Reader. You can, however, get a newer version using the process below (this installs a Windows version of Adobe Reader on Ubuntu).

For Adobe Acrobat Reader DC (running with Wine)

1. Install PlayOnLinux (as of 22 December 2018 you must get it this way, and not through Ubuntu Software, to ensure that you have the Wine version required to install Adobe Acrobat Reader DC)
   1. Press Ctrl + Alt + T
   2. Type sudo apt install wine:i386, press Enter , type your password, Enter , then type Y (when prompted), and Enter
   3. Click on the link above
   4. Click 'Ubuntu'
   5. For your Ubuntu version (to find that out, type lsb_release -a into Terminal and press Enter, look at the text next to codename), select the first line to be put into Terminal, press Ctrl + C then switch back to the Terminal, press Ctrl + Shift + V and press Enter. Follow the prompts in Terminal, do that for each of the four lines for your Ubuntu version.
2. Load PlayOnLinux (press Super, type PlayOnLinux, press Enter)
3. Click 'Install' (in the toolbar)
4. Type 'Adobe Acrobat Reader DC' in the search bar
5. Click 'Adobe Acrobat Reader DC'
6. Click 'Install' (bottom-right)
7. Follow the install screens
8. Once installed, click 'Adobe Acrobat Reader DC'
9. Click 'Run' (in the toolbar)

You'll need to open PlayOnLinux to run Adobe Reader DC each time (note that you can have this installed alongside Adobe Reader 9.5.5). You can drag the desktop file into the Launcher to get a button there, you can also add an icon for it in the Ubuntu Dash using alacarte ('Main Menu'). I might add instructions for that later (seems unlikely given that I wrote that over two years ago!).

Yes there is, but the support has been dropped. Check this out and follow instructions to install:

1. Open up terminal by pressing Ctrl+Alt+T on keyboard. When it opens, paste the command below and hit enter to add the repository:

   sudo add-apt-repository "deb http://archive.canonical.com/ precise partner"
   

   Type in your user password when it asks. Note that there’s no visual feed back when you typing a password.

2. After you added the repository, update package lists and install the acroread package by running below commands one by one:

   sudo apt-get update
   sudo apt-get install acroread
   

   Once installed, you should be able to open it from Unity dash or Application menu.

3. After properly installed Adobe Reader, don’t forget to remove the Canonical Partners repository for Precise:

   sudo add-apt-repository -r "deb http://archive.canonical.com/ precise partner"
   sudo apt-get update
   

4. How to Set Adobe Reader as default PDF reader:

Run command below in terminal to edit the config file:

    sudo gedit /etc/gnome/defaults.list

When the file opens, do:

Find out and change the line

application/pdf=evince.desktop

into:

application/pdf=acroread.desktop

Add below line into the end:

application/fdf=acroread.desktop
application/xdp=acroread.desktop
application/xfdf=acroread.desktop
application/pdx=acroread.desktop

Finally save the file and restart nautilus (run command nautilus -q in terminal) to apply changes.
