FYI: Microsoft broke secureboot in qemu-based VMs
by Sam Varshavchik 18 Sep '22

18 Sep '22

It is possible to run qemu VMs that emulate EFI and secureboot well enough for Windows to boot. This is still true, technically. Windows will boot. But it will not update reliably anymore. Microsoft broke it, ostensibly for "security reasons". Microsoft released a Windows update that will not install on qemu EFI VMs: https://www.bleepingcomputer.com/news/security/windows-kb5012170-secure-boo… dbx-update-may-fail-with-0x800f0922-error/ I was scratching my head, trying to figure out why this update won't install. A search on the cryptic error code brought up some random crap that wasted a ton of my time, doing things like resizing my system partition, almost bricking my VM (typical MS-Windows noise). Only after I got the bright idea of searching for both the error code and the update code itself did I find this article, and digging further found this: https://github.com/tianocore/edk2/discussions/3221 There's still a lot of things I don't understand. What is being blacklisted, exactly, here. The OVMF RPM – to the best of my understanding – is emulated hardware. How does running some PowerShell voodoo end up updating (emulated) hardware? And if it's not a magical hardware update, yammers about an update to the bootloader on the EFI system partition. Except that (at least in my case), the bootloader should be Microsoft's own bootloader, since I used Micorosoft's own tools to convert my BIOS Windows VM to an EFI one (mbr2gpt, that's how I was able to get a working EFI Windows VM). But the bottom line: this is now broken. Just an FYI…

backup tips: dump/restore
by Bill Cunningham 16 Sep '22

16 Sep '22

Hello all, Some time back I asked for opinions on backups. I had a lot of good opinions. I tried to backup some directories with dump. Which seemed to me to be quick and for what I was altogether looking for, for ext 2/3, pretty good. A 16GB filesystem was copied to a level 0 dump at around 1.5 GB. So it seems. I have several favorites, but in regards to dump, for those that are familiar with it; I did a level 0 dump and before I try restoring an erased partition I though I would clean up a few questions. As far at the partition's bootsector, would that happen to be in the dump file? And I am pretty sure partition table entries or any of the MBR are not saved. Timestamps and uuid type data of course I would not see to be saved. Although on my fstab, I use simple /dev/sdXX entries (/dev/sda1) not uuids. device.map might have to be regenerated too to get a booting system. I did not leave out anything system wise specifically by cli options. /var, /sys, /run, /tmp, /proc I am assuming are in the level 0 dump. The switches I used were: dump -0uv -e {some inode directory entries, not system specific} -f dmp Any tips on what I should save or expect to need to change when restoring this? BC

Hi there! What the shit is going on with Askfedora? I've registered on Fedoraproject, but when I try to login to Askfedora with my credentials, it gives me some crap about expired authentication token. Although I'm not logged in and can't have any token, let alone expired. -- I'm using Tutanota - the end-to-end encrypted email service

i have been using lists.fedoraproject.org. for support F20 -> F34 My platform environment is a small home system. i just read about Fedora 36/silverblue (immutable) & my inclination is to install silverblue, add flatpak's, and move on to verify F36 silverblue i also have a list of necessary application files for F36, that I need to verify before I move on. these include: Firefox including F36 OS +utils bash shell +(.XXX) OSB->studio pipewire audio http/https certbot ffmpeg image view files perl zoom My questions include; is anyone on this list using the silver blue desktop app? If yes, then... how easy is it to recover to an earlier version backup/reinstall user files how stable are the bind & activity logs how stable is Fedora 36 (silverblue) ?? would you recommend a migration to F36 silverblue now or wait for awhile?? tia, jackc...

email tracking, is it possible in fedora mail clients?
by stan 15 Sep '22

15 Sep '22

Hi, I just saw this article via Pocket in firefox, https://www.vox.com/recode/23332959/email-tracking-privacy and I wondered if that is an issue in fedora. It seems that in order for such tracking to work, it has to have the cooperation of the operating system, or at least the mail client. And, I would think that open source mail clients don't allow that. Am I right?

Fedora 36: How do I tell sound to NEVER use a mic?
by Thomas Cameron 13 Sep '22

13 Sep '22

I have two mics, one on my Brio web camera, and one on my motherboard. Every time I boot up, the Brio mic is selected, and I have to manually go in and tell the audio mixer that I want the onboard mic to be used. Sometimes I forget, join a WebEx or similar, and they are hearing me through my Brio, and that mic SUCKS compared to the one I have plugged in to the onboard sound card. I've set the onboard mic to be the default more times than I can remember, but when it reboots, the Brio mic is selected again. This is driving me nuts! What on Earth do I need to do to make the onboard sound card mic be the main/only one used? I am using Xfce, if that matters. When I fire up the mixer, it's using pavucontrol. If it matters, I have upgraded this system from F33 through F36. Thanks! Thomas

virt-manager alt-click passthrough?
by Alex 11 Sep '22

11 Sep '22

Hi, I'm using virt-manager to connect to a Windows 10 virtual machine, where I'm using photoshop. I need to send an alt-click key for some functions, but virt-manager is instead interpreting them. It isn't among the pre-configured options that can be sent. Is there a way to remap the alt key or alt-click combination so I can send it through to the virtual machine? I've also tried the RealVNC client/server trial, and I can't get that to connect at all. It does appear qemu/realvnc server is listening on 5900: tcp 0 0 127.0.0.1:5900 0.0.0.0:* LISTEN - qemu is also configured to listen (-spice port=5900,addr=127.0.0.1). I've also verified I can connect to port 5900 manually, so a Windows firewall is not the problem. Any ideas greatly appreciated.
