I will try to list all the solutions I've found.
First one. Tested solution: working, and very easy.
First install Wine on your Linux. Then download Adobe Digital editions. Link to download Adobe Digital editionsLink to download Adobe Digital editions
Then, install the file you dowloaded from Adobe (It was ADE_4.5_Installer.exe, for me), in the Wine virtual Window. If you don't know how to use wine, see this doc: How to install and use Wine on Linux
Second solution:
Install a virtual Windows on Linux. How to.
Third solution: If you failed to install virtual machine or open with Wine, and if you really need this program, install a dual boot on your computer Windows/Linux. How to dual boot Windows/linux on the same computer
4th solution, use a virtual Android phone (or a real one) and install the Adobe Digital editions for Android. Virtual smartphone software, Memu
You can also try to emulate MacOs, or iOS.
There are solutions to remove the DRM, and so convert the acsm into epub, but there are no legal, so I don't think I'm allowed to write them.
