[12:06] <Mexit> Hello,I just tested the latest image of Ubuntu 20.10. Unfortunately, there is no loopback.cfg file that allows the system to boot directly from the ISO image (through grub2).Will this be permanent?
[12:08] <tomreyn> Mexit: was there ever such a file in the past? why would it be needed to boot a system off the iso?
[12:17] <Mexit> tomreyn: yes. This file has existed for as long as I can remember, including 20.04.This is a simplified version of the grub.cfg file with an additional kernel parameter: iso-scan/filename=$isofile.
[12:17] <Mexit> allow to boot Multiple ISO from USB via Grub2
[12:18] <oerheks> isoboot? https://help.ubuntu.com/community/Grub2/ISOBoot ~ https://askubuntu.com/questions/1186040/grub-command-loopback-loop-does-not-work-on-ubuntu-19-10   
[12:18] <oerheks> i hope this is not an UEFI machine
[12:25] <Mexit> oerheks: bios and UEFI. Yes, isoboot, but with this file you have original boot menus. Here my universal configfile for all ubuntu family: https://github.com/Mexit/MultiOS-USB/blob/master/config/ubuntu/ubuntu.cfg
[12:32] <tomreyn> hmm i see, so there's /boot/grub/loopback.cfg in the Ubuntu Desktop 20.04.1 ISO
[12:32] <tomreyn> also in the Ubuntu Server (Live) 20.04.1 ISO
[12:34] <tomreyn> Mexit: maybe loopback.cfg is only added for proper releases. have you looked at the 20.10 beta?
[12:42] <Mexit> It is also missing there (20.10 beta)
[12:43] <Mexit> tomreyn : This file was always, in every release
[12:44] <tomreyn> hmm, maybe ask in #ubuntu-server, too (unlike #ubuntu-desktop they're open to "support" questions).
[12:45] <tomreyn> or even file a bug
[12:46] <tomreyn> there's also #ubuntu-quality where developers might pick up on it
[12:46] <tomreyn> i see you got a reply in #ubuntu-devel
[18:34] <LuckyMan> I'm using flutter and android studio on 20.10, and when running a desktop app I have lots of Gtk errors.
[18:34] <LuckyMan> and nothing is shown
[18:35] <LuckyMan> only a white window
[18:41] <tomreyn> LuckyMan: and this version of the software, "flutter", is said to be compatible to (yet unreleased) ubuntu 20.10?
[18:44] <oerheks> https://snapcraft.io/install/flutter/ubuntu ???
[18:45] <LuckyMan> tomreyn, I don't know, but since I'm learning desktop apps, I'm using the dev channel on flutter, so I guess they are probably developing to the next version of Ubuntu
[18:47] <tomreyn> oh snap it's a snap
[18:48] <tomreyn> well, i guess that as long as you installed the snap using --classic, it can work.
[18:49] <tomreyn> if it supports gtk3+ then the snap should automatically pull in all gtk3 libs that are needed to make it work.
[18:49] <LuckyMan> it mostly works but when running, it gives Gtk errors, on a loop, and doesn't show anything
[18:51] <LuckyMan> Idk if it has to do with Gtk or if has to do with the last flutter update, or if it has to do with 20.10
[18:51] <tomreyn> i guess you could visit the developer website and look for support options there, or contact the flutter team: https://snapcraft.io/flutter
[18:52] <LuckyMan> but I also had lots of trouble latelly with android-studio (which I'm not using on 20.10) on 20.04 because of the last update.
