| eoli3n_ | Hi | 08:34 |
|---|---|---|
| eoli3n_ | is there any plan to let desktop image use autoinstall ? | 08:35 |
| eoli3n_ | as you removed kickstart support since 20.04, what is the recommended way to automate desktops desployments ? | 08:45 |
| eoli3n_ | deployments* | 08:46 |
| eoli3n_ | what is the nickname of Ryan Harper here please ? | 08:57 |
| xnox | eoli3n_: i'm not sure what you mean by kickstart support being removed. | 12:15 |
| xnox | eoli3n_: desktop installation automation has not been changed for years, and can be done in 20.04 the same way it has always been possible to do. | 12:15 |
| eoli3n_ | actually i was wrong, just reworking on this. Problem is not that kickstart is removed, problem is that i can't deploy in EFI mode with kickstart | 12:15 |
| xnox | eoli3n_: what's not working for you? | 12:16 |
| xnox | i deploy ubuntu desktop with EFI always. | 12:16 |
| eoli3n_ | with kickstart ? | 12:16 |
| xnox | yes | 12:16 |
| eoli3n_ | hm | 12:16 |
| xnox | eoli3n_: your partitioning does have ESP right? | 12:16 |
| xnox | one kind of needs that =) | 12:16 |
| eoli3n_ | how do you trigger EFI deploy mode with kickstart ? | 12:17 |
| xnox | by booting the machine in EFI mode | 12:17 |
| === jamesh_ is now known as jamesh | ||
| xnox | with either EFI iPXE or EFI Http boot | 12:17 |
| eoli3n_ | yes, but when i tested, my booted EFI host deploy legacy system, but maybe i did forget to adapt my partition table | 12:17 |
| eoli3n_ | xnox what iso do you use ? | 12:24 |
| eoli3n_ | the main desktop one ? | 12:24 |
| eoli3n_ | i used the netboot one, which can't deploy in efi mode | 12:25 |
| xnox | eoli3n_: yes i always use the desktop one. | 12:25 |
| xnox | and i network boot initrd & kernel from it, using shim + network build of grub grubnetx64.efi. And pass url=http://path/to/matching-desktop.iso | 12:26 |
| xnox | eoli3n_: i only always deploy desktop using the desktop.iso with preseeding. | 12:26 |
| xnox | that's the only way to deploy Ubuntu Desktop the right way. | 12:27 |
| eoli3n_ | any link which describe the process ? | 12:27 |
| eoli3n_ | xnox is there any chance to adapt it to nfsroot the iso ? | 12:29 |
| eoli3n_ | i manage 800 nodes, deployed by group of 40 | 12:30 |
| eoli3n_ | i can't let each node get a full 2G iso | 12:30 |
| xnox | eoli3n_: "i can't let each node get a full 2G iso" => but they will need to get 2G of data one way or another to complete desktop install. | 12:31 |
| xnox | so not sure it matters _when_ they do that =) from initrd on boot, or elsehow. | 12:31 |
| xnox | But there is nfs root mount option too, if you can export nfs mount. | 12:31 |
| xnox | https://discourse.ubuntu.com/t/netbooting-the-live-server-installer/14510 => is how to setup pxeboot, it does work with UEFI too if your UEFI supports pxe (see like the first comment). Instead of the live-server.iso you just use the desktop one. | 12:31 |
| eoli3n_ | xnox nfsroot is much more efficient | 12:34 |
| eoli3n_ | because of the server itself | 12:34 |
| eoli3n_ | 40x dl of a big file is worse than letting clients get a lots of little files | 12:35 |
| xnox | boot=casper netboot=nfs nfsroot=192.168.122.73:/srv/iso-mount/ => make sure that you export the full mounted desktop iso; and that initrd&vmlinuz you boot are from it. | 12:35 |
| xnox | if you can't mount the iso make sure to copy _all_ of it, including hidden files. | 12:35 |
| xnox | there are some details on automating the preseed of Ubiquity https://wiki.ubuntu.com/UbiquityAutomation | 12:36 |
| xnox | i.e. booting with automatic-ubiquity and supplying the preseed. | 12:36 |
| xnox | i.e. cp -r /mnt/. /srv/nfs/somewhere => note the '.' in /mnt/. to ensure all the hidden files are copied and exported. | 12:37 |
| eoli3n_ | i already does this | 12:37 |
| eoli3n_ | do* | 12:38 |
| xnox | eoli3n_: cool. so yeah, my preference is to boot in uefi, either download/mount iso from the initrd (url=http://...) or do nfsroot mount, and automate that. There are no reasons not to boot in EFI mode. | 12:41 |
| xnox | eoli3n_: if you don't want to use PXE / tftp, you can point your servers to perfrom UEFI HTTP boot => point them at shim + grubnetx64.efi | 12:42 |
| eoli3n_ | but you use kickstart or ubiquity only ? | 12:42 |
| eoli3n_ | i use ipxe and tftp | 12:42 |
| xnox | eoli3n_: there is no native support for kickstart, and never was. it always translated kickstart into d-i/ubiquity compatible preseed. | 12:42 |
| xnox | eoli3n_: thus i prefer to use native formats, thus yes, i simply write/serve/boot with preseed for ubiquity. | 12:43 |
| eoli3n_ | i know, but i already have a kickstart script for legacy mode | 12:43 |
| xnox | or autoinstall.yml for the subiquity live-server iso. | 12:43 |
| eoli3n_ | xnox oula oula oula oula | 12:43 |
| eoli3n_ | lets restart fresh, to let you understand from where i come, to where i want to go, and where i'm now | 12:43 |
| xnox | eoli3n_: kickstart should work too. I can't remember if we build preseed-kickstart into the ubiquity images. | 12:43 |
| xnox | let me check that. | 12:44 |
| xnox | eoli3n_: you also did say taht your kickstart doesn't work, rigth? =) in EFI... hence if it doesn't work, is it really there? | 12:44 |
| eoli3n_ | i used ubuntu ""kickstart"" to deploy legacy hosts with pxelinux/tftp. Now i need to deploy in EFI mode so i worked a lot on server iso to use autoinstall, i'm really near to get it work | 12:45 |
| eoli3n_ | but i wonder if its the right way | 12:45 |
| eoli3n_ | now i don't have much time so i need to choose a quick and proper way | 12:46 |
| eoli3n_ | there is no good documentation about this | 12:46 |
| eoli3n_ | that's sad | 12:46 |
| eoli3n_ | a kind of guide | 12:47 |
| xnox | eoli3n_: when you say you used ubuntu ""kickstart"" can you show me what you mean? | 12:47 |
| eoli3n_ | yes, just a sec | 12:47 |
| xnox | just a few snippets / quotes of it. | 12:47 |
| xnox | eoli3n_: your request is not unique. I am pondering to run a public demo netboot/install server that "works" and then let people copy it. | 12:48 |
| eoli3n_ | xnox https://x0.at/UWZ.txt | 12:48 |
| eoli3n_ | i need to deal with dualboot | 12:48 |
| xnox | eoli3n_: the only bad thing about your preseed is the part of "generate partitioning script" | 12:49 |
| eoli3n_ | i can't do without it | 12:49 |
| eoli3n_ | because of dualbooting | 12:49 |
| xnox | eoli3n_: if you change the sfdisk <<EOSF bits to use label gpt, add EFI partition, then add disk_partone => it will start to work in EFI mode too. | 12:49 |
| eoli3n_ | ahhh | 12:50 |
| eoli3n_ | ok | 12:50 |
| xnox | eoli3n_: you need to adjust that one, to create ESP | 12:50 |
| eoli3n_ | that was my question | 12:50 |
| xnox | eoli3n_: that's what i did tell you at the very start of our conversation =) | 12:50 |
| xnox | "xnox>eoli3n_: your partitioning does have ESP right?" | 12:50 |
| eoli3n_ | yep yep | 12:50 |
| xnox | if you have no ESP in your partitioning, when installer gets to "now i install shim+grub into ESP, it goes oh oh" | 12:51 |
| xnox | eoli3n_: and it's best to always create ESP and always use GPT => it works with legacy mode, efi mode, dual boot, with any windows&linux combo, etc. | 12:51 |
| eoli3n_ | ok | 12:51 |
| xnox | even if the deploy is done in bios or efi mode, it will installs and boot in either. | 12:52 |
| xnox | our ubuntu desktop is versatile like that, and allows to boot itself irrespective of how one installed it. | 12:52 |
| eoli3n_ | so lets try to adapt this instead of working with autoinstall | 12:52 |
| eoli3n_ | xnox http://archive.ubuntu.com/ubuntu/dists/bionic/main/installer-amd64/current/images/netboot/netboot.tar.gz | 12:53 |
| eoli3n_ | is this able to deploy in EFI mode ? | 12:53 |
| xnox | eoli3n_: it's incomplete. and does not support secureboot. | 12:54 |
| eoli3n_ | i don't use secureboot | 12:54 |
| eoli3n_ | what do you mean by "incomplete" ? | 12:54 |
| xnox | eoli3n_: you'd need to add shimx64.efi / uefi-ipxe / grubnetx64.efi to get secureboot (shim), uefi netboot capability (ipxe or httpboot grubnetx64.efi from focal+) | 12:55 |
| xnox | eoli3n_: one needs more than just that, to boot in efi mode is what i mean. | 12:55 |
| eoli3n_ | if i extract kernel+initrd and boot it with ipxe, no problem then, right ? | 12:56 |
| xnox | yeah, that works. | 12:56 |
| xnox | some expect the shim/signed uefi ipxe/grub/configs to be in that tarball too. | 12:56 |
| eoli3n_ | so in that case, what is the benefit to prefer the main desktop.iso ? | 12:56 |
| xnox | eoli3n_: that thing, will never deploy the same desktop as the desktop.iso will. | 12:57 |
| eoli3n_ | lets precise something | 12:57 |
| eoli3n_ | i just need the installer to deploy the minimal system | 12:57 |
| xnox | eoli3n_: no option to install minimum ubuntu desktop; no option to install correct matching nvidia drivers; no way to configure and install OEM kernel for the certified hardware | 12:57 |
| eoli3n_ | then i use ansible to deploy everything else | 12:57 |
| eoli3n_ | ansible does all those things for me | 12:57 |
| xnox | no option to have the correct defautl snaps installed; following the correct tracks | 12:57 |
| xnox | no oem config... | 12:58 |
| eoli3n_ | hm | 12:58 |
| xnox | eoli3n_: some/none of the above maybe of interest to you | 12:58 |
| xnox | eoli3n_: and/or you may already be fixing those things separately. | 12:58 |
| eoli3n_ | but then will not be any 22.04 netboot so | 12:58 |
| eoli3n_ | lets switch to the main desktop.iso | 12:58 |
| xnox | eoli3n_: i also don't see ubiquity supporting kickstarts. and there is new installer in progress which will have autoinstall.yml support just like server iso | 12:58 |
| eoli3n_ | thanks for your help xnox, i was a bit lost | 12:58 |
| eoli3n_ | "there is new installer in progress which will have autoinstall.yml" | 12:59 |
| eoli3n_ | i need this ! | 12:59 |
| xnox | eoli3n_: swithcing to the main desktop.iso / and or testing that, may help to futureproof your deployements. | 12:59 |
| eoli3n_ | ok | 12:59 |
| xnox | eoli3n_: see the New Installer articles / github repo where it is being developed. At the moment early design stages. | 12:59 |
| eoli3n_ | so two moves : move to desktop.iso, and translate the kickstart part to ubiquity script | 12:59 |
| eoli3n_ | any link about this ? | 13:00 |
| xnox | eoli3n_: yes, if you boot / deploy your kickstart, there should be somewhere in /var/log/installer the translation. Cause d-i does translates it into preseed. It should be a good enough starting point. | 13:00 |
| xnox | eoli3n_: plus you don't actually do anything special much. | 13:01 |
| xnox | you pick the right disk; and configure ansible | 13:01 |
| xnox | https://code.launchpad.net/ubuntu-test-cases => we have many preseeds automation for various things | 13:02 |
| eoli3n_ | does ubiquity automation only, support %post chrooted script and %pre ? | 13:02 |
| xnox | eoli3n_: https://bazaar.launchpad.net/~ubuntu-test-case-dev/ubuntu-test-cases/desktop/view/head:/preseeds/default.cfg is more or less all you need. | 13:02 |
| xnox | but you do need preseed/late_command to do more things kind of like what your %post does to do ansible | 13:02 |
| xnox | and i think you will want to do a hook before partma to figure out the right drive to autopartition with a shell script | 13:03 |
| xnox | cause i think you are trying to iterate things and find the one you like. | 13:03 |
| xnox | for that you can use partman/early_command | 13:03 |
| xnox | eoli3n_: or check what your kickstart got translated into preseed terms. | 13:04 |
| xnox | i am sorry, i have to go, but i will come back to read backscroll here. | 13:04 |
| eoli3n_ | thanks a lot for your help | 13:06 |
| === mfo_ is now known as mfo | ||
| rbasak | cjwatson: any further thoughts on my git-ubuntu rich history thread please? I think, with your feedback in mind, it still makes sense to implement my proposed spec (but with a singular Vcs-Git-Ref), with a view to switching to "push" at some far point in the future. Do you concur? | 13:07 |
| cjwatson | rbasak: Since you're treating the rich history as best-effort, I think I concur for now, yes. | 13:10 |
| rbasak | OK, thanks! And for your detailed feedback. | 13:11 |
| cjwatson | rbasak: I do think you should add at least some kind of fallback-and-retry for temporary failures even in the short term - they won't be *that* uncommon | 13:11 |
| cjwatson | rbasak: Even if it's just the kind of fairly basic thing that lazr.restfulclient does (I mean in terms of overall algorithm, rather than specifics) | 13:12 |
| rbasak | Understood. | 13:13 |
| rbasak | I can add some short-lived retries that will hold up the importer worker (and therefore other imports) for an hour or two. | 13:14 |
| rbasak | Leaving the import to move on to others and then come back to it is harder, since I don't currently have a soft-fail mechanism in the queue architecture. | 13:15 |
| rbasak | That's something I should probably add, but isn't there yet. | 13:15 |
| cjwatson | rbasak: Seems reasonable. Most such temporary failures are likely to be service-wide anyway | 13:33 |
| eoli3n_ | xnox any chance to get my ks file to work as is ? | 14:26 |
| eoli3n_ | i found the translation in /var/lib/preseed/log, but it doesnt contains everything | 14:26 |
| eoli3n_ | "xnox: eoli3n_: i also don't see ubiquity supporting kickstarts." | 14:40 |
| eoli3n_ | hm.. ok | 14:41 |
| eoli3n_ | xnox some questions : | 14:55 |
| eoli3n_ | - how to generate my partman-pre script | 14:56 |
| eoli3n_ | - how to run multiple command in chroot after install | 14:56 |
| eoli3n_ | https://help.ubuntu.com/lts/installation-guide/armhf/apbs05.html#preseed-hooks | 14:56 |
| eoli3n_ | this is really unclear | 14:56 |
| eoli3n_ | found this about multiple command in chroot : https://github.com/dsgnr/Ubuntu-16.04-Unattended-Install/blob/master/preseed.cfg#L195 | 15:02 |
| xnox | eoli3n_: yeah ';' works for multiple commands. not nice, but it's what it is. | 15:12 |
| xnox | "how to generate my partman-pre script" => not sure what you mean. | 15:12 |
| eoli3n_ | https://x0.at/UWZ.txt | 15:13 |
| eoli3n_ | see the # PRE # part | 15:13 |
| xnox | eoli3n_: if you want to control everything by hand, something like this works => https://secopsmonkey.com/custom-partioning-using-preseed.html | 15:13 |
| xnox | which disables all the automatic partitioning, and does it by hand. | 15:13 |
| eoli3n_ | i do want automatic partitionning | 15:13 |
| eoli3n_ | i just want to force to restore part1 which is windows | 15:14 |
| eoli3n_ | my pre part is to not overwrite windows if present | 15:14 |
| eoli3n_ | if not present, it prepare the place | 15:14 |
| eoli3n_ | that's why i dump diskid | 15:14 |
| eoli3n_ | and regenerate as is | 15:14 |
| eoli3n_ | it actually clear everything except windows part | 15:15 |
| eoli3n_ | clears | 15:15 |
| eoli3n_ | can i wget that script ? | 15:15 |
| eoli3n_ | d-i partman/early_command string wget -O /tmp/pre.sh http://prodpeda-cesium.infra.domain.fr/preseed/fds/pre.sh; /bin/bash /tmp/pre.sh | 15:17 |
| xnox | eoli3n_: so you either have empty disk => wipe everything; or you have windows on part1. | 15:17 |
| eoli3n_ | lets try this | 15:17 |
| eoli3n_ | xnox i don't get your question | 15:17 |
| eoli3n_ | i do have both | 15:17 |
| xnox | eoli3n_: when you have part1 => do you have enough disk space after part1? or do you need to resize windows too? | 15:17 |
| eoli3n_ | if this is a new host, first use, then prepare part1, else if windows present, keep it functionnal | 15:17 |
| eoli3n_ | i have enough space | 15:18 |
| xnox | eoli3n_: cause i wonder if you can just select use largest free, and it will always do the right thing. | 15:18 |
| eoli3n_ | that's what i use | 15:18 |
| eoli3n_ | preseed partman-auto/init_automatically_partition select biggest_free | 15:19 |
| xnox | hm | 15:19 |
| xnox | oh, so you create empty part1, such that later you can have windows on it? | 15:19 |
| xnox | interesting. | 15:19 |
| eoli3n_ | better than that | 15:19 |
| xnox | or if it is there already, don't touch it? | 15:19 |
| eoli3n_ | if windows is present, is "recreate" over it to keep it intact | 15:19 |
| eoli3n_ | yes | 15:19 |
| xnox | interesting. | 15:19 |
| xnox | do we currently break windows? =/ | 15:20 |
| eoli3n_ | that was the only way i found | 15:20 |
| xnox | cause i would have hoped that biggest_free doesn't break/touch windows that is there anyway. | 15:20 |
| eoli3n_ | i had some issues yes | 15:20 |
| xnox | ah, netboot.tar breaks things yes. | 15:20 |
| eoli3n_ | windows needs a repair if disk_id changed | 15:20 |
| xnox | ubiquity doesn't => it has more logic. | 15:20 |
| eoli3n_ | oh ! | 15:20 |
| eoli3n_ | lets try without then | 15:21 |
| xnox | eoli3n_: ah, interesting. maybe we still break disk_id, but i thought we didn't. | 15:21 |
| eoli3n_ | but with GPT partition table, maybe its different | 15:21 |
| xnox | eoli3n_: it would be interesting to try without anything. Imho, it is a bug if it breaks windows and doesn't just use biggest_free. | 15:21 |
| eoli3n_ | problem is that i fix two cases | 15:22 |
| xnox | true.... | 15:22 |
| eoli3n_ | first is windows is present : so without anything it "would" work, as you say | 15:22 |
| eoli3n_ | but if nothing is already present, the place will not be prepared if i drop my script | 15:22 |
| xnox | hopefully doing "d-i partman/early_command string wget -O /tmp/pre.sh http://prodpeda-cesium.infra.domain.fr/preseed/fds/pre.sh; /bin/bash /tmp/pre.sh" will just work as you mentioned earlier. | 15:22 |
| eoli3n_ | ok | 15:22 |
| eoli3n_ | maybe i can use sfdisk in another way | 15:23 |
| eoli3n_ | to just create the part without restauring the full partition table | 15:23 |
| eoli3n_ | in 2 steps | 15:23 |
| eoli3n_ | restoring | 15:23 |
| eoli3n_ | running | 15:30 |
| eoli3n_ | just a thing : how to disable the filesystem check at startup ? | 15:30 |
| eoli3n_ | that one : https://x0.at/xsf.png | 15:32 |
| xnox | eoli3n_: it's turned off by default in hirsute; i think you can boot with fsck.mode=skip and it will not run. | 15:34 |
| eoli3n_ | what is hirsute ? | 15:34 |
| eoli3n_ | lets try "fsck.mode=skip" | 15:34 |
| xnox | eoli3n_: Ubuntu 21.04 => development version of the next Ubuntu release. | 15:34 |
| eoli3n_ | oh ok | 15:35 |
| eoli3n_ | fsck.mode=skip doesnt disable the filesystem check | 15:38 |
| eoli3n_ | https://x0.at/zL_.txt | 15:38 |
| eoli3n_ | if you have more exemples of seed files, i take | 15:45 |
| eoli3n_ | (filesystem check seems to still print but does not run (stuck at 0% then disapear)) | 15:51 |
| oSoMoN | xnox, what's the state of https://bileto.ubuntu.com/#/ticket/4491, are you still working on it? | 15:52 |
| xnox | oSoMoN: that approach failed, but yes still working on it. | 16:09 |
| oSoMoN | ack, thanks | 16:09 |
| xnox | eoli3n_: stuck at 0% then disappear => is not running =) the visual UX improved later. | 16:10 |
