Yeah. Adobe is basically easy mode. It is why so many people, erroneously, claim that Kobo has no DRM (it also uses Adobe Digital Editions).
Guides for that are basically everywhere and versions don’t matter at all. Was going to set that up with just a bottle but it is harder to get ADE to run under wine than it is to use the drm removal plugin with it and I have this Windows VM just sitting in a folder…
If you find an author you like, check their website. There are decent odds they directly sell ebooks or link to their publisher’s website first. I’ve heard mixed reports on it, but some people claim buying direct from the publisher gives the writer a bigger cut (and, obviously, buying from them directly does).
Usually resutls in a DRM free ebook without any effort.
