Since this appears to be a tech support thread, I'm just going to test my luck here. I tried about 4 different ways to run GW2 on Ubuntu 18.04, 3 of them pretty much worked (Armored Vehicle Scripts / manually get all the Wine things / Lutris) up to the moment of downloading all the files for gw2.dat in the installation process through the launcher. There is always about 10% missing and then it gives up and there is no way to get it to finish. It doesn't freeze, the megabytes shown are constantly rising, but 1: up to a point of being way too big, 2: the gw2.dat doesn't grow anymore, 3: It never gets more of the files mentioned on the launcher, 4: it never gets away from 90% or 91%.Running the game anyways (since it is ready to play at like 30% already) is, as far as I know, known to have unplayable performance and does so in my case too. Right now, I want to see if I can get 100% on windows first, and if so, just copy the files to my Ubuntu system (the wiki tells me they are not machine dependant). I've seen kind of similar launcher issues reported in here and maybe someone has an idea of where it might come from, since not everyone can use windows.@jinxlaw.9467 did that work for you? Update: another thread mentions something that could be related
