[00:05] <arraybolt3[m]> Can someone who has the ability to legally install WIndows 10 or 11 try to do a Lubuntu installation alongside Windows? I see someone having problems with that on Discourse and I've noticed that os-prober isn't trying to detect other operating systems on my system, so I'm wondering if maybe the os-prober problem that was fixed early on in the 22.04 cycle has resurfaced.
[00:07] <arraybolt3[m]> (I'd do it myself but I don't own any Windows 10 licenses or hardware with a Windows 10 license.)
[00:09] <arraybolt3[m]> (Also things have calmed down in $PERSONAL_LIFE so I should be back.)
[00:11] <kc2bez[m]> I could probably do it in a VM tomorrow. I am not wanting Windows on any of my bare metal hardware though.
[00:11] <arraybolt3[m]> Yeah me neither.
[00:12] <arraybolt3[m]> I should probably buy a license at some point in the future so I can do testing, but I don't ever want any version of Windows to touch my bare-metal hardware again. Blech.
[00:12] <kc2bez[m]> Technically you can install it you just can't activate it.
[00:12] <guiverc> arraybolt3[m], lubuntu kinetic (22.10)?
[00:13] <tsimonq2> Here's the thing about that...
[00:13] <tsimonq2> That's on purpose
[00:13] <arraybolt3[m]> guiverc: Nope, Jammy.
[00:13] <tsimonq2> I think juliank sent an email to the ML?
[00:13] <tsimonq2> Basically, we need to enable Calamares to run it once in the installer with a disclaimer
[00:14] <tsimonq2> They discovered a new attack vector in GRUB which allows sideloading of malicious code onto the partition that contains GRUB
[00:14] <guiverc> give me a little; I'll boot jammy (daily at most a few days old; SRU testing) and see if it detects a w10 I think I have on samsung thing
[00:14] <tsimonq2> I work around this on my local system by explicitly defining a config variable in GRUB
[00:14] <tsimonq2> But unfortunately this one isn't a bug... it's by design, and we know the situation isn't ideal right now
[00:15] <tsimonq2> If anyone has the chance to find the mailing list archives associated with this issue I'd appreciate it, probably either ubuntu-release or ubuntu-devel. Otherwise I'll likely look tomorrow
[00:15] <arraybolt3[m]> Simon Quigley: I thought that it was purposefully disabled in GRUB and that Ubuntu purposefully enabled it again.
[00:15] <tsimonq2> I'd appreciate some context on the latter, if you could 
[00:16] <arraybolt3[m]> Simon Quigley: Context about the re-enabling of it?
[00:16] <tsimonq2> Correct, pretty please :)
[00:17] <arraybolt3[m]> Simon Quigley: I actually don't know, I believe guiverc told me that it was behaving the current, secure but bad way early on in the Jammy cycle and then later on it started auto-detecting things right again. I may have misunderstood.
[00:18] <tsimonq2> I know you can re-enable it, and I do simply for my own use
[00:18] <tsimonq2> I'm not sure about the decision that was reached 
[00:18] <kc2bez[m]> I am subscribed to -devel and I can't find it. It must be -release.
[00:19] <arraybolt3[m]> One moment...
[00:19] <arraybolt3[m]> I can't find it in -release either.
[00:19] <tsimonq2> No rush, I need to get back to $sidejob (in spite of current circumstances) so I'll catch you guys a bit later/here and there
[00:19] <arraybolt3[m]> Searched from October 2021 to April 2022.
[00:20] <kc2bez[m]> Hmm
[00:20] <tsimonq2> But I do remember seeing something about this...
[00:20] <tsimonq2> Maybe it was on debian-devel?
[00:20] <tsimonq2> If you guys can't find it I can search debian-private too...
[00:20] <tsimonq2> I know I saw an email about this though.
[00:20] <guiverc> arraybolt3[m], booting recent daily of jammy (SRU'd calamares from proposed) detects the windows 10 install (original OEM install though was factory reset prior to be given to me) on `samsung 700t1c-p10aat (i5-3317u, 4gb, 3rd gen.core.intel.graphics.4000)`
[00:20] <kc2bez[m]> I believe you my search wasn't too exhaustive 
[00:21] <tsimonq2> No worries. Take care :)
[00:21] <arraybolt3[m]> guiverc: OK. I meant that when you install alongside W10 it doesn't detect it and put it in the boot menu. Though you probably don't want to risk nuking that system.
[00:22] <kc2bez[m]> It would have included debian-develop though too. I can look more tomorrow after some time spent horizontal.
[00:22] <kc2bez[m]> s/develop/devel/
[00:23] <arraybolt3[m]> December 2021 on ubuntu-devel, found it.
[00:23] <arraybolt3[m]> Hey look: https://lists.ubuntu.com/archives/ubuntu-devel/2021-December/041769.html
[00:23] <guiverc> not really; so you mean update-grub isn't detecting it... My system has jammy installed & w10 is detected  (never really select it though; last time was just to prove to someone I did have a windows but not knowing password I couldn't login)
[00:23] <kc2bez[m]> Ah, I didn't go far enough back.
[00:23] <guiverc> update-grub on my install detects & offers the w10... My w10 has fastboot off & hibernate disabled
[00:24] <arraybolt3[m]> guiverc: Hmm. Any chance you can show the contents of /etc/default/grub?
[00:24] <guiverc> arraybolt3[m], from installed system?  (I'm on live currently; only looked what calamares offered)... I can reboot & provide what is installed if helpful
[00:25] <arraybolt3[m]> Yeah, from the installed system. Just to see if maybe OS-PROBER was manually reenabled or something.
[00:28] <guiverc> arraybolt3[m], https://pastebin.ubuntu.com/p/7ZKPKzcsnm/
[00:30] <arraybolt3[m]> guiverc: Hmm, thanks, and that's weird. I wonder what makes GRUB decide when to use the prober and when not to.
[00:35] <guiverc> yeah I recall issues early in the cycle (tracking doc is where I'd look for clues), but they were resolved & I ignored it as I tested all releases with a winXP  (my d755-5 has a copy still) but rarely on that samsung (w10)... I commonly test with other GNU/Linuxes (which suffered same issue with prober when it impacted jammy)
[00:37]  * guiverc rebooted samsung & selected checked grub (if windows didn't show, I'd likely not notice!) & yep 'windows boot manager' is there & when selected got to w10 greeter... rebooted again at that point
[00:51] <Roberalz[m]> <arraybolt3[m]> "Yeah, from the installed system...." <- edit /etc/default/grub and add the line GRUB_DISABLE_OS_PROBER=false
[00:52] <Roberalz[m]> You try that? 
[00:53] <Roberalz[m]> With a update-grub2 
[00:53] <arraybolt3[m]> Roberalz: I know that doing that will fix the problem, but my issue is with whether the problem exists at all by default. Also, my laptop only has one OS installed, I just notice that it tells me that os-prober isn't being used. I don't need it, but others who dual-boot do.
[00:53] <arraybolt3[m]> (Well, OK, only one host OS installed, I have an entire zoo of VMs but that's different.)
[00:58] <Roberalz[m]> <arraybolt3[m]> "Roberalz: I know that doing that..." <- It has been disabled by default
[01:00] <Roberalz[m]> https://askubuntu.com/questions/1414245/why-do-i-get-warning-os-prober-will-not-be-executed-to-detect-other-bootable-p
[01:00] <arraybolt3[m]> Yeah. I thought they changed their minds but I guess not.
[01:02] <Roberalz[m]> A script call has been added as posted on askubuntu.
[01:26] <tsimonq2> <arraybolt3[m]> "Hey look: https://lists.ubuntu...." <- YES that's the one
[01:35] <Roberalz[m]> <tsimonq2> "YES that's the one" <- Thanks for the info
