zahroc: Is there a documented copy of the web api that is used in lgogdownloader?
Just wondering how to know that https://www.gog.com/user/data/games gives a list of games by ID, etc
TIA!

Sude: Here's documentation that Yepoleb wrote

CrenVerdis: Maybe someone else can help...
Got the following error code:

'cren@server:~$ lgogdownloader --download --directory ~/cryptexternal/gog-installer/ --limit-rate 25000
Getting game names (4/4) 92 / 92
terminate called after throwing an instance of 'std::length_error'
what(): basic_string::_M_replace
Aborted (core dumped)'

Running on odroid m1s (ARM single board computer) under Ubuntu Server 20.04 LTS (headless)
Also added to an open ticket on github, but I'll edit my post there if something comes out of here.

Sude: What version are you using?
I hope you're not trying to use the version from Ubuntu 20.04 repositories because it is really old (version 3.5 which is from 2019)

Since the output is starting with "Getting game names" it is at most version 3.16.
Version 3.17 had some minor changes to getting game names and details so update to version 3.17 to see if it fixes the issue.

CrenVerdis: Maybe add a tip/hint/caution NOT to use the distros repos, (…)

vv221: On an up-to-date LTS Ubuntu, LGOGDownloader 3.12 is provided, not the 3.5 version.

Here I am not using the 3.12 build but the 3.15 one and it still works nicely (on a Debian Bookworm, backported from when the 3.15 build was provided in Debian Sid), so in my experience you do not need the latest build for basic use.
