| stealthadmin | Hello, I am trying to preseed an 18.04 ubuntu server installation. I have tried using a debian preseed file and passing the path of the file to the kernal on install. This preseed file has been validated by debian-installer and was previously used for a 14.04 instalation. We have also investigated using an answers.yaml file to seed the installation, but there is not much documentation on this method. Have there been breaking changes f | 15:47 |
|---|---|---|
| CarlFK | answers.yaml? | 15:50 |
| CarlFK | I would post the details of your problem - like you don't even say you have a problem | 15:51 |
| stealthadmin | I am unable to seed the installation. When booting the live iso, none of the preseeded values have been used. | 15:54 |
| stealthadmin | From what I can tell, answers.yaml is another way to preseed subiquity. Although the only references I can find are here: https://ubuntuforums.org/showthread.php?t=2390710 and here https://github.com/CanonicalLtd/subiquity/blob/master/examples/answers.yaml | 15:56 |
| CarlFK | unable to seed - how are you giving the file to the installer? | 15:59 |
| CarlFK | I host it on a http server on my lan, and add a kernel append: url=hostname | 15:59 |
| CarlFK | it sounds like the installer isn't aware of your file | 16:00 |
| stealthadmin | By passing the file path to the kernal as a parameter : file=/cdrom/preseed/mypreseed.seed | 16:00 |
| CarlFK | try url=file://cdrom/... or maybe url=file:///cdrom... | 16:01 |
| CarlFK | I think I have seen file= but I am not sure now | 16:02 |
| stealthadmin | Ok let me give that a try. Is there somewhere in a log that would say it failed to find the file? | 16:02 |
| CarlFK | for me, the installer errors and halts. but I also have debug=5 or something that might cause that | 16:03 |
| stealthadmin | I have been trying to follow this documentation: https://help.ubuntu.com/lts/installation-guide/s390x/apbs01.html#preseed-methods | 16:03 |
| CarlFK | if you want to try to trace what I use.. which works, but is pretty convoluted... | 16:05 |
| CarlFK | https://salsa.debian.org/debconf-video-team/ansible/blob/master/scripts/mk_usb_installer.sh#L29 | 16:05 |
| CarlFK | the preseed files are way over here: https://salsa.debian.org/debconf-video-team/ansible/tree/master/roles/tftp-server/files | 16:06 |
| CarlFK | because they get used by both "mk usb install media" and "pxe boot the installer" | 16:07 |
| CarlFK | the usb stick is made with that shell script, the pxe server is built with ansible - using the same files for both is ... convoluted | 16:07 |
| stealthadmin | Is the debug level for the installer something I can also pass as a kernal parameter? | 16:11 |
| CarlFK | yes | 16:13 |
| CarlFK | loking ... it is in/around that script... | 16:13 |
| CarlFK | https://salsa.debian.org/debconf-video-team/ansible/blob/master/scripts/syslinux.cfg#L5 | 16:15 |
| CarlFK | APPEND --- debconf/priority=high auto=true netcfg/dhcp_timeout=60 | 16:15 |
| CarlFK | debconf/priority=high | 16:15 |
| stealthadmin | Ok I think it might be a problem for how I am creating the iso. I will look over your script and keep playing with it. Thank you for the help. | 17:02 |
| CarlFK | are you burning to CD or making a usb thumb drive? | 17:04 |
| CarlFK | I 'hate' making CDs - so hard to make changes | 17:05 |
| stealthadmin | Using a thumbdrive. Me too haha, CDs are the worst | 17:05 |
| CarlFK | you might want to try that script - it tries to support Ubuntu too | 17:14 |
| CarlFK | I waffle between ubuntu and debian - currently using debian because it is more tested, and I haveent taken the time to test ubuntu in a while | 17:15 |
