Failed to download launcher and permission errors on release 20201210

[someonewithpc]

I installed this app on Arch Linux with the PKGBUILD from https://aur.archlinux.org/packages/ftba/#comment-779578 with the version updated to 202012101153-ce008c54b4-release. The app runs, but the modpacks don't (specifically FTB Interactions). I noticed that /opt/FTBA is owned by root, but changing the owner to my user and group made it so there was no output (and it still didn't work). Running with sudo exits with code 0 without doing anything.

The first time I ran it I got an error saying it failed to download the minecraft launcher.

Here's the output of running FTBApp as installed

$ FTBApp

[voidstarr]

I am having similar issues with the FTBA_unix_202012101153-ce008c54b4-release.sh script from feed-the-beast.com on Ubuntu Mate 20.04. On first launch, the minecraft launcher is not unpacked properly in ~/.ftba/bin. Resolving that issue leaves me with with the "Unable to initialize MineTogether Connect!" error above.

[ThePaul-T]

The MineTogether Connect message is expected and does not impact game launching. The launcher is missing in the log above.

[someonewithpc]

@ThePaul-T No, I know it is missing, but I don't know where to get it from, couldn't find it in any folder, and clearly it didn't work automatically

[ThePaul-T]

It will have downloaded it but failed to extract it, it will be inside ~/.ftba/bin, there will be a tar.gz, just extract it there and it should work.

[gigabit101]

I believe this issue should be resolved with the changes that have been made with how we handle downloading the vanilla launcher If the issue continues please do let us know.
