| marcoagpinto | Heya | 06:17 |
| ducasse | good morning | 07:54 |
| marcoagpinto | :) | 07:59 |
| croraf | Ubuntu Bionic (16.04) had "bionic linux-hwe" kernel flavors, which were like "advanced" kernels matching some of the latest mainline kernels? | 16:13 |
| oerheks | no, backported kernels from next release | 16:15 |
| oerheks | !hwe | 16:15 |
| croraf | oerheks, so each time the LTS "point" realese happens an "hwe" version is created? | 16:20 |
| oerheks | yes, when next Groovy 20.10 is released, HWE will be available | 16:21 |
| croraf | but i dont understand what is the difference, because the "regular" kernel is also updated | 16:21 |
| croraf | oerheks, and also the bionic linux is based on 4.13-4.15 mainline kernels | 16:22 |
| croraf | bionic linux-hwe is based on 4.18-5.3 mainline kernels | 16:23 |
| croraf | and bionic linux-hwe 5.0 is based on 5.0 mainline kernel | 16:23 |
| croraf | So there is no rule basically. | 16:24 |
| oerheks | don't look at the 'mainline stuff' .. | 16:25 |
| oerheks | those are for testing | 16:25 |
| croraf | OK. But for example bionic-linux has 4.13-4.15 ubuntu kernel version | 16:25 |
| croraf | bionic linux hwe has 4.18-5.3 and bionic linux hwe 5.0 has 5.0 versions | 16:26 |
| croraf | there is also hwe 5.4 | 16:26 |
| croraf | So if I understood correctly each new point version comes with the new kernel "flavor"? | 16:27 |
| croraf | Like 16.04.1 came with hwe, 16.04.2 came with hwe 5.0, 16.04.3 came with hwe 5.4? | 16:27 |
| croraf | oerheks, | 16:27 |
| croraf | Actually from https://wiki.ubuntu.com/Kernel/Support?action=AttachFile&do=view&target=18.04.x+Ubuntu+Kernel+Support+Schedule.svg I see that: | 16:33 |
| Maik | croraf: after each new ubuntu release you should get a new kernel with HWE afaik | 16:34 |
| Maik | some time after that is | 16:34 |
| croraf | Hmmm, I dont think this is how it goes | 16:35 |
| Maik | say Ubuntu 20.10 will ship 5.7 or 5.8, you'll get that on the LTS release as update/upgrade | 16:35 |
| Maik | well... i don't know any different way it should go | 16:36 |
| Maik | i could be mistaken (just woke up) | 16:36 |
| Maik | https://wiki.ubuntu.com/Kernel/LTSEnablementStack | 16:37 |
| croraf | I was checking this link, it is extremely confusing and out of date Maik | 16:37 |
| ducasse | every new release means a hwe kernel for older lts releases | 16:37 |
| Maik | it's still the same procedure croraf | 16:38 |
| Maik | ducasse: so i was basically right? | 16:38 |
| ducasse | yeah, you are | 16:38 |
| croraf | ducasse, so every major release? | 16:38 |
| croraf | not point releases? | 16:38 |
| ducasse | the point releases come with hwe | 16:39 |
| croraf | So when 18.10 came out the bionic-hwe came out? When 19.04 came out the bionic-hwe-5.0 came out and when 19.10 came out the bionic-hwe-5.4 came out? | 16:39 |
| ducasse | yeah | 16:39 |
| Maik | yes | 16:39 |
| ducasse | but a little after the release | 16:40 |
| croraf | Thats why we have only 3 hwe for 18.04 and we have 4 releases after 18.04? | 16:40 |
| croraf | 18.10 19.04 19.10 20.04 | 16:40 |
| croraf | we should have 4 hwe kernel lines for bionic. | 16:41 |
| croraf | ducasse, Maik | 16:41 |
| ducasse | if the 20.04 kernel has been released yet for bionic, i'm not sure it has | 16:41 |
| croraf | I see now that eon ermine (19.10) didnt come with the kernel line | 16:43 |
| Maik | https://www.omgubuntu.co.uk/2020/08/ubuntu-18-04-5-lts-released-with-linux-kernel-5-4 | 16:44 |
| croraf | And focal (20.04) came with 5.4 kernel. So it might be that 20.04 is mapping to "bionic linux hwe 5.4" | 16:44 |
| croraf | And that 19.10 didnt come with a hwe. | 16:45 |
| Maik | bionic should have 5.4 now | 16:45 |
| croraf | Yes, it has "bionic linux hwe 5.4" kernel line | 16:45 |
| lotuspsychje | ubottu> linux-image-generic-hwe-18.04 (source: linux-meta): Generic Linux kernel image (dummy transitional package). In component main, is optional. Version 5.4.0.42.46 (focal), package size 1 kB, installed size 17 kB | 16:46 |
| croraf | Before that there was "bionic linux hwe 5.0" kernel line | 16:46 |
| croraf | It might be that only .04 versions come with a kernel line? | 16:47 |
| croraf | 18.04 19.04 20.04 | 16:47 |
| croraf | And if you check this image https://wiki.ubuntu.com/Kernel/Support?action=AttachFile&do=view&target=18.04.x+Ubuntu+Kernel+Support+Schedule.svg | 16:47 |
| croraf | Then you have complete mess and confusion. | 16:48 |
| Maik | 19.10 had 5.3 and was also HWE, except 5.3 is EOL now and wasn't a LTS kernel | 16:51 |
| Maik | so what's your point actually | 16:51 |
| Maik | that the documentation isn't up to date? | 16:51 |
| croraf | I want to understand how and when these kernel lines come? Maik | 16:52 |
| lotuspsychje | https://wiki.ubuntu.com/Kernel/LTSEnablementStack | 16:53 |
| Maik | as we said a couple of times before now: they come to LTS after a while when a new version of Ubuntu is released | 16:53 |
| ducasse | this is really more of a topic for -discuss, it's not really a support issue | 16:53 |
| Maik | we are in -discuss? ;) | 16:54 |
| ducasse | oh, sorry, me blinking :) | 16:54 |
| Maik | hehehe... had that to a while back | 16:54 |
| ducasse | i'm following too many things at once | 16:54 |
| Maik | no problem, same here :) | 16:55 |
| ducasse | there were some changes to how hwe works a while back, you might find that in uwn | 16:55 |
| ducasse | i don't recall the details | 16:55 |
| ducasse | iirc, they were mostly regarding how hwe is pulled in and when, but they clarified the whole deal | 16:57 |
| croraf | lotuspsychje, hehehe, 4th time someone gives me this link :) | 16:57 |
| croraf | Maik, if this is true, why are there 4 releses after 18.04 but only 3 hwe? | 16:59 |
| ducasse | the latest bionic is .5 | 17:00 |
| Maik | croraf: ^ | 17:01 |
| ducasse | .1 did not come with a hwe kernel, that leaves .2, .3, .4 and .5 | 17:01 |
| Maik | yep, so that makes 4 | 17:02 |
| ducasse | then we agree on the math :) | 17:02 |
| croraf | Buuuut, there are only 3 hwe kernels, not 4. | 17:03 |
| croraf | Maik, ducasse | 17:03 |
| croraf | the bionic hwe, bionic hwe 5.0, bionic hwe 5.4 | 17:03 |
| Maik | and 5.3 | 17:04 |
| croraf | Maik, there is no such: https://people.canonical.com/~kernel/info/kernel-version-map.html | 17:04 |
| ducasse | there's a table here - https://www.thomas-krenn.com/en/wiki/Ubuntu_LTS_Hardware_Enablement_Stack_information | 17:04 |
| croraf | ducasse, nice that you found this :) | 17:05 |
| ducasse | 4.18, 5.0, 5.3 and 5.4 | 17:05 |
| Maik | 18.04.4 (RN)5.3(from Ubuntu 19.10)HWE KernelFebruary 2020August 2020 | 17:05 |
| coconut | yes, firefox 80 is now updated in focal :) | 17:05 |
| Maik | from that table | 17:05 |
| * Maik uses Chrome | 17:06 | |
| croraf | ^ | 17:06 |
| croraf | Chrome also updated today to 85 | 17:06 |
| ducasse | croraf: does that answer your question? | 17:06 |
| croraf | But how come this does not match in my table ducasse Maik - which is official | 17:06 |
| ducasse | which table? | 17:07 |
| croraf | And also the 16.04 only have 4 versions | 17:07 |
| Maik | croraf: again, because it hasn't been updated maybe? Volunteers work on the documentation afaik | 17:07 |
| croraf | ducasse, https://people.canonical.com/~kernel/info/kernel-version-map.html | 17:07 |
| croraf | I posted this before at :04:38 | 17:08 |
| croraf | Maik, I mean this table is very much up to date always | 17:08 |
| croraf | And this Thomas Kren site is unofficial | 17:08 |
| Maik | but what's your problem with it? You have the latest kernel and it runs fine doesn't it? | 17:09 |
| croraf | It does not | 17:09 |
| * Maik doesn't have any issues | 17:09 | |
| croraf | I do have 20.04 GA latest though | 17:09 |
| croraf | let me check my table to see the hwe for 16.04 | 17:10 |
| Maik | need to get ready for work in a few, see you all later :) | 17:10 |
| croraf | xenial has only 1 hwe in my table .... :( | 17:11 |
| croraf | ok have a nice day Mail | 17:11 |
| croraf | Maik | 17:11 |
| ducasse | you need to ask the kernel team about the table, i can't comment on it | 17:12 |
| ducasse | if you have a problem with your kernel then that is a support issue :) | 17:13 |
| Maik | thank croraf, but actually night :) | 17:13 |
| croraf | ducasse, i know but i want to understand the context to actually be able to solve | 17:18 |
| croraf | now i've been suggested to install the oem kernel | 17:18 |
| croraf | How does the "oem" line differ from "hwe" line? | 17:19 |
| ducasse | lotuspsychje: can you answer this? ^^ | 17:27 |
| croraf | ducasse, on top of this, if I install this oem kernel, would I be able on boot to choose which kernel to boot with? | 17:28 |
| croraf | *will I be able | 17:28 |
| ducasse | yeah, you should be able to choose from grub | 17:29 |
| croraf | cool, so I'm actually safe to try this, with respect to crashing my system or losing data? | 17:29 |
| croraf | ducasse, | 17:29 |
| croraf | I can always simply switch to the current kernel | 17:30 |
| ducasse | i've never used the oem kernels myself, but i would think it's pretty safe to try one out | 17:30 |
| coconut | What kind of privileges do one need to edit !factoids ? | 17:51 |
| ducasse | i think only certain ops can do that | 17:55 |
| ducasse | maybe all of them, not sure | 17:55 |
| coconut | :) i ask this because i saw a typo in one of them coming by | 17:59 |
| ducasse | if you report it in -ops they will fix it | 18:00 |
| coconut | #ubuntu-quality: !support | 18:00 |
| coconut | <ubot5> Ubuntu 20.10 (Focal Fossa) support in #ubuntu+1. This channel is for testing 20.10 and reporting results here: http://iso.qa.ubuntu.com/qatracker/milestones/413/builds | 18:00 |
| coconut | ok, will try that, thank you :) | 18:01 |
| ducasse | you can also try -offtopic, several ops hang out there | 18:04 |
| ducasse | i'll also mention it if i see one | 18:05 |
