| wholesum | how do i rebuild grub? I can access the system partition (and the LVM) using the liveCD. it's 18.04.1. | 03:11 |
|---|---|---|
| wholesum | i've been struggling for the past 24 hrs, i'm afraid i'm going to lose my job... | 03:11 |
| wholesum | i already tried to use refind, reinstalling grub, and a lot of other things. | 03:12 |
| sarnold | wholesum: if you mean, how to ask grub to rebuild the menu, configuration, etc, then try 'update-grub' -- the /etc/default/grub file points there | 03:27 |
| wholesum | i'm in grub rescue now | 03:27 |
| wholesum | sarnold: you can see the grub info here (menuentry ubuntu, ignore above) https://pastebin.com/AuiAvrjY | 03:28 |
| sarnold | wholesum: you might have better success in #ubuntu -- many of the folks here haven't seen grub in years, but the #ubuntu folks help debug install problems a lot more often | 03:30 |
| wholesum | sarnold: what are you using? refind? i had better luck with that, but not enough to boot my system | 03:31 |
| wholesum | i can do away with grub, there is only one OS in the system | 03:31 |
| wholesum | BTW not a install problem. server has been running fine for almost 1 year. last night I rebooted and it told me no OS found | 03:32 |
| sarnold | wholesum: I've never needed to do anything like this, ever | 03:33 |
| sarnold | wholesum: refind is in universe, so it wouldn't be the preferred choice; efibootmgr is in main, it's probably the ubuntu preferred tool | 03:34 |
| wholesum | how would i go about configuring it from a live CD? set the boot order to use the partition where ubuntu is installed? | 03:35 |
| sarnold | you could chroot to the mounted path.. | 03:39 |
| sarnold | it'd be something like: (untested) (pretend the instal;led system is mounted on /mnt/root) mount -obind /proc/ /mnt/root/proc ; mount -obind /sys/ /mnt/root/sys/ ; chroot /mnt/root /bin/bash | 03:40 |
| wholesum | will try! | 03:50 |
| wholesum | so once i have a shell inside the installed system i play with efibootmgr? | 03:53 |
| wholesum | sarnold: I'm in the shell for the installed system | 04:06 |
| wholesum | I cleaned up efibootmgr to have only a single entry: ubuntu | 04:09 |
| lotuspsychje | wholesum: why is your server not up to date to .2? | 04:29 |
| wholesum | lotuspsychje: didn't want an upgrade to bork it up and can't afford downtime on it... | 04:30 |
| lotuspsychje | wholesum: there are like tons of security updates out, and now your system is also borked | 04:30 |
| wholesum | it was fully up to date, on a daily basis | 04:31 |
| lotuspsychje | wholesum: is that an intel cpu? | 04:31 |
| wholesum | but on 18.04.1 | 04:32 |
| wholesum | yes, i5 | 04:32 |
| wholesum | disk is NVME SSD with secure boot | 04:32 |
| lotuspsychje | wholesum: we had several users reporting unable to boot on the new !mds | 04:32 |
| wholesum | whats the new !mds? i'm not using raid | 04:33 |
| lotuspsychje | wholesum: did you change uefi settings recently? | 04:33 |
| lotuspsychje | !mds | 04:33 |
| ubottu | Microarchitectural Data Sampling is a security issue with Intel processors. Update your system to receive the kernel and microcode patches. Visit https://wiki.ubuntu.com/SecurityTeam/KnowledgeBase/MDS for more info and recommendations. | 04:33 |
| wholesum | ah yes, the new vuln | 04:33 |
| wholesum | uefi settings have not been changed in months... | 04:33 |
| lotuspsychje | wholesum: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1829620 | 04:34 |

| wholesum | i am the single user on this machine, running only trusted apps. i am going to disable all mitigations later | 04:34 |
| lotuspsychje | maybe worth testing? | 04:34 |
| lotuspsychje | ill be out for breakfast first | 04:35 |
| wholesum | i doubt that's it, but i will look at it | 04:35 |
| wholesum | it's a lenovo box | 04:35 |
| wholesum | no cryptsetup | 04:36 |
| lotuspsychje | wholesum: you might also wanna browse https://bugs.launchpad.net/ubuntu/+source/grub-installer/+bugs?orderby=importance&start=0 | 05:06 |
| wholesum | thx and good morning | 05:06 |
| wholesum | :) | 05:06 |
| lotuspsychje | there's tons of grub installer bugs noticed recently | 05:06 |
| wholesum | i reinstalled from 18.04.2 server (not live) | 05:06 |
| wholesum | i have an image of the previous install system partition | 05:07 |
| lotuspsychje | ah | 05:07 |
| wholesum | i'm thinking about booting into the desktop live usb again, and copying this image over the (same size) current system partition. do you think it would work? | 05:08 |
| wholesum | setting up everything again will take weeks... | 05:08 |
| lotuspsychje | wholesum: dont you have a backup of your configs, or can preserve your /home on a new installer? | 05:13 |
| wholesum | lotuspsychje: too many applications installed and configured, and 4 users. but i do have a backup of /home inside the img of the entire system partition | 05:14 |
| raddy | Hello Everybody | 07:57 |
| raddy | I am using ubuntu 16.04.5 in AWS | 07:59 |
| raddy | tmpfs has 377M free space | 07:59 |
| raddy | But it still says there is no free space | 08:00 |
| tomreyn | which tmpfs? | 08:00 |
| raddy | You mean ? | 08:01 |
| raddy | tmpfs 377M 0 377M 0% /run/user/1000 | 08:01 |
| tomreyn | raddy: so you're trying to write to somewhere below /run/user/1000/ ? | 08:02 |
| raddy | I am trying write in /tmp/ | 08:02 |
| tomreyn | then the above output is not relevant, try this: df -h /tmp | 08:03 |
| raddy | Filesystem Size Used Avail Use% Mounted on | 08:05 |
| tomreyn | raddy: now repeat the line which wasn't transferred since it started with a slash. add a blank space as the first character | 08:07 |
| raddy | tomreyn: I don't get you, but I don't have separate /tmp file system | 08:09 |
| tomreyn | raddy: so how much free unallocated space do you have in / ? | 08:11 |
| tomreyn | raddy: alternatively, run this and post the url: df -h /tmp 2>&1 | nc termbin.com 9999 | 08:12 |
| raddy | 2.4Gb free space is available | 08:13 |
| === gislaved73 is now known as gislaved | ||
| tomreyn | raddy: that's not a lot. if it's an ext{2,3,4} file system, then 5% are reserved for the root user by default | 08:21 |
| tomreyn | 5% of the total file system | 08:22 |
| tomreyn | another explanation could be that all inodes are in use: df -hi /tmp | 08:22 |
| raddy | tomreyn: You nailed it. that is the issue | 08:30 |
| raddy | tomreyn: find . -type f | wc -l shows the /tmp/ has only 80 files | 08:34 |
| RoyK | tomreyn: df reports the available space after the 5% is subtracted. also, tmpfs doesn't have that. the reserved space can be tuned with tune2fs -m<something> /dev/sd<something> | 08:35 |
| raddy | But 512k inodes being shown as used | 08:35 |
| raddy | Please help | 08:37 |
| raddy | I got it | 08:38 |
| tomreyn | you'll need to create a new file system, specifying a higher amount of inodes (-I) | 08:39 |
| tomreyn | actually i didn'T explain this properly, read the man page, please | 08:40 |
| tomreyn | actually -N is what you'd need,-I just changes the inode size. | 08:41 |

| jiffe | so I'm trying to install ubuntu 18.04 on a desktop, it installs find but doesn't boot, no grub menu or anything I just get a flashing cursor in the top right | 19:44 |
| jiffe | boot order is correct, its booting from hd | 19:44 |
| lordcirth | jiffe, you are installing Ubuntu desktop or server ISO? EFI or BIOS? | 19:45 |
| jiffe | ubuntu server, not sure about the later let me check | 19:46 |
| jiffe | yeha looks like bios, nothing about uefi in here | 19:53 |
| jiffe | or efi | 19:53 |
| jiffe | this is an old P4 machine | 19:53 |
| lordcirth | jiffe, pentium 4? 32 or 64bit? | 20:02 |
| jiffe | 64 bit | 20:03 |
| jiffe | I see people having success with something similar running boot-repair from a live cd | 20:06 |
| tomreyn | jiffe: which installer did you use (.iso filename)? and which version of the installer? were there any warnings or errors while installing? | 22:03 |
| tomreyn | also, with hardware this old (with known unfixed security bugs), you'll want the latest firmware available to be installed, i'd say. did you check you have that? | 22:05 |
