This is how I got ADE to work on Linux Mint 20.3:
Code:
Adobe Digital Editions 2.0 on Linux
1) Install wine-stable from winehq.org
2) Install winbind from Synaptic (for SMB)
3) Install winetricks from Synaptic
4) Install dotnet35 and dotnet35sp1 from winetricks
5) Install ADE 2.0; setup may freeze near the end, so Ctl+C the terminal to kill wine
6) Run winecfg and select the Drives tab; assign a drive letter to the Kobo's mountpoint
, e.g. /media/user/Kobo eReader -> D:\
7) Under drive type, force drive D to be treated as a floppy drive (for RW access to the Kobo)
8) Open ADE and authorise the PC; close ADE
9) Connect the Kobo
10) Open ADE again and authorise the Kobo
11) Add the ACSM to ADE to get the book
12) Copy the book to the Kobo
