[12:06] 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] Mexit: was there ever such a file in the past? why would it be needed to boot a system off the iso? [12:17] 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] allow to boot Multiple ISO from USB via Grub2 [12:18] 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] i hope this is not an UEFI machine [12:25] 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] hmm i see, so there's /boot/grub/loopback.cfg in the Ubuntu Desktop 20.04.1 ISO [12:32] also in the Ubuntu Server (Live) 20.04.1 ISO [12:34] Mexit: maybe loopback.cfg is only added for proper releases. have you looked at the 20.10 beta? [12:42] It is also missing there (20.10 beta) [12:43] tomreyn : This file was always, in every release [12:44] hmm, maybe ask in #ubuntu-server, too (unlike #ubuntu-desktop they're open to "support" questions). [12:45] or even file a bug [12:46] there's also #ubuntu-quality where developers might pick up on it [12:46] i see you got a reply in #ubuntu-devel [18:34] I'm using flutter and android studio on 20.10, and when running a desktop app I have lots of Gtk errors. [18:34] and nothing is shown [18:35] only a white window [18:41] LuckyMan: and this version of the software, "flutter", is said to be compatible to (yet unreleased) ubuntu 20.10? [18:44] https://snapcraft.io/install/flutter/ubuntu ??? [18:45] 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] oh snap it's a snap [18:48] well, i guess that as long as you installed the snap using --classic, it can work. [18:49] if it supports gtk3+ then the snap should automatically pull in all gtk3 libs that are needed to make it work. [18:49] it mostly works but when running, it gives Gtk errors, on a loop, and doesn't show anything [18:51] 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] 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] 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.
