| samba35 | i have messup with my ubuntu 18.04 server with grub loader there is now only memory test entry are there there is no linux-version entry | 04:56 |
| samba35 | how do i fix this problem ? | 04:56 |
| cpaelzer | good morning | 06:32 |
| cpaelzer | samba35: that seems that no kernel at all was found on your last update grub | 06:32 |
| cpaelzer | samba35: there might be more options, but I'd try to boot from USB/CD | 06:33 |
| cpaelzer | samba35: then chroot into your actual system | 06:33 |
| cpaelzer | and then check why there is no kernel, fix that up | 06:33 |
| cpaelzer | and eventually run sudo update-grub | 06:33 |
| cpaelzer | that should then detect the kernel that you made available and update the boot tables as needed | 06:33 |
| cpaelzer | then cross fingers, reboot and done | 06:34 |
| cpaelzer | samba35: I think the live CD also has a boot-repair option that fixes most common issues | 06:34 |
| samba35 | sorry cpaelzer | 06:40 |
| cpaelzer | for what samba35? | 06:41 |
| samba35 | i try to boot from dvd and mount it but it give erros | 06:41 |
| cpaelzer | well then, disk broken maybe | 06:41 |
| cpaelzer | what kind of errors | 06:41 |
| samba35 | error with dpkg and unable to find some files | 06:42 |
| cpaelzer | provide a pastebin of the commands you tried and maybe the logs and dmesg that was created along | 06:42 |
| cpaelzer | hmm | 06:42 |
| cpaelzer | are those dpdk errors after mount+chroot? | 06:42 |
| cpaelzer | did you bind mount /proc, ss and dev ? | 06:42 |
| samba35 | is it possible to boot from another harddisk and make broken disk as a slave and try to repiar ? | 06:42 |
| samba35 | no | 06:42 |
| cpaelzer | samba35: that is exactly what you already do with the CD | 06:42 |
| cpaelzer | CD is the "other disk" | 06:43 |
| cpaelzer | and you try to repair from there right | 06:43 |
| samba35 | currenty i am on 16.04 and broken disk as a slave | 06:43 |
| samba35 | will i able to fix this now ? | 06:43 |
| cpaelzer | no one can tell you that in advance, but give it a try | 06:44 |
| cpaelzer | before you chroot you should like | 06:44 |
| cpaelzer | 1. mount the disk on /mnt | 06:44 |
| cpaelzer | 2. for f in proc sys dev ; do mount --bind /$f /mnt/$f ; done | 06:45 |
| cpaelzer | 3. chroot /mnt | 06:45 |
| cpaelzer | then you are as if you'd be in your hard disk's system | 06:45 |
| cpaelzer | not sure if you need network tricks, but that would be a start | 06:45 |
| cpaelzer | there check /boot and if there is a kernel as it should be | 06:45 |
| cpaelzer | then run sudo update-grub what does it say ... | 06:45 |
| samba35 | ok | 06:45 |
| samba35 | let me try | 06:45 |
| samba35 | sda1 is mount as a /media/tesuser/some numbers | 06:54 |
| samba35 | what is ss ? | 06:55 |
| samba35 | mount /media/tesuser/637d0aee-9232-11e8-9c61-2ed34b5b4932/proc/ /current (from where i have booted ) that drive any mount point or old salave disk mount point ? | 06:58 |
| samba35 | mount: /media/tesuser/637d0aee-9232-11e8-9c61-2ed34b5b4932/proc is not a block device | 06:59 |
| samba35 | ok | 06:59 |
| samba35 | done | 07:00 |
| samba35 | with --bind | 07:00 |
| cpaelzer | yeah it just means "be also available there for when I late chroot" | 07:04 |
| samba35 | from where i have to run update-grub ? | 07:05 |
| samba35 | salave /18.04 disk or currnt 16.04 disk | 07:06 |
| samba35 | ok let me boot from cdrom and try | 07:09 |
| samba35 | cpaelzer, thanks i will be back later after trying this | 07:10 |
| cpaelzer | samba35: you want to do that "inside" the chroot which is on the disk you want to fix | 07:11 |
| samba35 | ok | 07:11 |
| samba35 | chroot: failed to run command '/bin/bash': No such file or directory | 07:17 |
| samba35 | in old disk in /boot i can see initrd.img-4.15.0-42-generic.dpkg-bak | 07:23 |
| samba35 | initrd.img-4.15.0-42-lowlatency.dpkg-bak | 07:23 |
| samba35 | initrd.img-4.19.2-041902-generic.dpkg-bak | 07:23 |
| samba35 | and when i run update-grub here i show currnt disk kernl 3.x | 07:24 |
| samba35 | w /usr/sbin/grub-mkconfig: 37: /usr/share/grub/grub-mkconfig_lib: cannot create /dev/null: Permission denied | 07:28 |
| samba35 | mount but why ? | 07:29 |
| samba35 | a /usr/sbin/grub-probe: error: cannot find a device for / (is /dev mounted?). | 07:29 |
| samba35 | cpaelzer, a /usr/sbin/grub-probe: error: failed to get canonical path of `/dev/mapper/ubuntu-root'. | 07:36 |
| samba35 | now this error | 07:36 |
| cpaelzer | hmm seems like lvm root | 07:38 |
| cpaelzer | righ tnow I'm not sure without checking myself what special consideration apply | 07:38 |
| samba35 | ok | 07:38 |
| cpaelzer | your list of kernel/initrd mentions only backup files | 07:38 |
| cpaelzer | no actual kernel/initrd there ?! | 07:39 |
| samba35 | yes | 07:39 |
| cpaelzer | well, whatever the reason is that is at least part of your issue | 07:39 |
| samba35 | there was error with dpkg and i google some site and mess up | 07:39 |
| cpaelzer | you'd want to install at least one kernel | 07:39 |
| samba35 | yes | 07:39 |
| samba35 | will booting from 18.04 dvd will help ? | 07:40 |
| cpaelzer | yeah the case look half-broken already, this gets hard to fix-by-remote-hints | 07:40 |
| samba35 | and rescue mode | 07:40 |
| cpaelzer | booting a different DVD will not make it any different IMHO | 07:40 |
| samba35 | ic | 07:40 |
| cpaelzer | you still need to install a proper kernel on the main disk in the chroot | 07:40 |
| cpaelzer | and then update-grub | 07:40 |
| cpaelzer | and sort out whatever the lvm setup makes you need in additon | 07:41 |
| samba35 | ok | 07:41 |
| samba35 | thanks cpaelzer back soon thanks | 07:46 |
| lordievader | Good morning | 09:02 |
| kstenerud | Does anyone know how to generate a control file from a control.in file? | 09:46 |
| mwhudson | kstenerud: there's no one way, make -f rules control ? | 09:48 |
| samba35 | E: Sub-process /usr/bin/dpkg returned an error code (1) | 10:01 |
| samba35 | how to fix this | 10:01 |
| LeMike | Would this be the right place for some rsync things? I tried using --filter=":e- .gitignore" but unfortunately it still downloads all files instead of ignoring some. Why could that be? | 10:29 |
| LeMike | damn it. forget about this. the ":" is a directory merge so the .gitignore of the sender will be used (and not mine as receiver). | 10:37 |
| ahasenack | good morning | 11:09 |
| peetaur2 | I don't know when or how, but at some point, vsftpd and LDAP were working fine, and now it fails. with lftp client, it started doing this: ls: Login failed: 500 OOPS: cannot locate user entry:username | 11:27 |
| peetaur2 | and if I change it to use the sshd pam service instead, it then says ls: Login failed: 530 Login incorrect. | 11:28 |
| ahasenack | you need to checkout which ldap searches are being done, and what their result is | 11:35 |
| ahasenack | peetaur2: ^ | 11:35 |
| peetaur2 | I basically did that. | 11:46 |
| peetaur2 | but restarting nslcd fixed it .... :/ | 11:46 |
| peetaur2 | why should getent, ssh, etc. all work fine using nslcd, but vsftpd needed it restarted? silly thing | 11:46 |
| ahasenack | ah, the cache? | 11:47 |
| peetaur2 | nslcd does caching, yes | 11:48 |
| ahasenack | rbasak: hey, I just saw something interesting in a debian package | 16:53 |
| ahasenack | rbasak: debian builds samba with glusterfs support, so their samba-vfs-modules package ships /usr/lib/x86_64-linux-gnu/samba/vfs/glusterfs.so | 16:54 |
| ahasenack | and that links with libglusterfs.so.0, which comes from glusterfs-common | 16:54 |
| ahasenack | rbasak: but their samba-vfs-modules package has no dependency on glusterfs-common. Instead, they have a Recommends | 16:54 |
| ahasenack | root@oriented-mastodon:~# dpkg -s samba-vfs-modules|grep gluster | 16:54 |
| ahasenack | Recommends: glusterfs-common, libcephfs2 (>= 12.2.8), libdbus-1-3 (>= 1.9.14) | 16:54 |
| ahasenack | is that a valid trick? | 16:55 |
| ahasenack | shlibs didn't seem to have picked up the linkage between /usr/lib/x86_64-linux-gnu/samba/vfs/glusterfs.so (samba-vfs-modules) and /usr/lib/x86_64-linux-gnu/libglusterfs.so.0 (glusterfs-common) | 16:55 |
| ahasenack | in the package's description: | 16:58 |
| ahasenack | Note: The runtime dependencies of vfs_ceph, vfs_glusterfs and vfs_snapper are | 16:58 |
| ahasenack | moved to Recommends. | 16:58 |
| nacc | ahasenack: so if you install samba-vfs-modules (but not it's recommends) and then configure samba to use gluster, does it segfault/crash? | 17:01 |
| ahasenack | nacc: it would definitely fail to load that module. I think it still starts up, but I would have to check | 17:01 |
| rbasak | Plugin modules are weird | 17:01 |
| rbasak | It might be reasonable to leave it as a recommends or even a suggests | 17:02 |
| ahasenack | also, what does ubuntu do, since it installs recommends by default? What does it do when it cannot find a recommends? | 17:02 |
| rbasak | I think it will not take any action on a recommends it cannot fulfil. But that might need checking. | 17:03 |
| rbasak | "The Depends field should be used if the depended-on package is required for the depending package to provide a significant amount of functionality." | 17:03 |
| rbasak | From policy | 17:03 |
| rbasak | For something like samba-vfs-modules, glusterfs may not be treated as "significant". | 17:04 |
| ahasenack | right | 17:04 |
| ahasenack | but the question is, what would britney do? :) | 17:04 |
| rbasak | It doesn't know so it doesn't care. | 17:04 |
| ahasenack | I mean, at migration time | 17:05 |
| ahasenack | if it would treat recommends as depends or not | 17:05 |
| ahasenack | or "whatever apt would do" is the answer | 17:05 |
| rbasak | Oh | 17:05 |
| rbasak | I see what you're asking now. I don't know. Good question. | 17:05 |
| ahasenack | I'll find out | 17:06 |
| ahasenack | we could drop that bit of delta if this works and is acceptable | 17:06 |
| cpaelzer | coreycb: jamespage: is that nova test error anything you triggered or could fix https://objectstorage.prodstack4-5.canonical.com/v1/AUTH_77e2ada1e7a84929a74ba3b87153c0ac/autopkgtest-disco/disco/amd64/n/nova/20181206_155403_69eef@/log.gz ? | 21:13 |
| cpaelzer | the libvirt upload I did certainly didn't trigger that | 21:13 |
| cpaelzer | was a s390x only one line change to vfio handling | 21:14 |
| cpaelzer | so I wonder if there is anything going on that you know avoiding that I have to debug and find out on my own tomorrow | 21:14 |
| * cpaelzer is lazy before going to bed and hope the world fixes my issues | 21:14 | |
| evit | I was thinking the other day. It would be awesome if apt update would notify if you needed to reboot or not like it does on the desktop. | 21:15 |
| sdeziel | evit: motd is updated with the reboot needed notice | 21:16 |
| coreycb | cpaelzer: I've been trying to figure it out all day. I made a little progress at https://bugs.launchpad.net/ubuntu/+source/nova/+bug/1807262 | 21:17 |
| ubottu | Launchpad bug 1807262 in nova (Ubuntu) "stein unit tests fail with sqlalchemy.exc.NoSuchTableError: migration_tmp" [High,Triaged] | 21:17 |
| evit | sdeziel, I'm talking about after you do a manual apt update && apt upgrade | 21:19 |
| evit | @sdeziel, I disabled MOTD | 21:20 |
| coreycb | cpaelzer: something changed w sqlite | 21:20 |
| sdeziel | evit: I guess you could have a post-apt hook to do what the motd in question was doing | 21:20 |
| cpaelzer | coreycb: if you don't find something towards your EOD | 21:21 |
| cpaelzer | would you mind filing a force-badtest for now to unblcok me and potentially others | 21:22 |
| cpaelzer | that would give you tim eto sort it out | 21:22 |
| sdeziel | evit: if you are looking for something to let you know which services would need a restart (more frequent than reboot-needed), you may want to look at https://github.com/simondeziel/check-deleted-libs/blob/master/check-deleted-libs </self promotion> | 21:22 |
| cpaelzer | thanks for the bug reference, I'll refresh tomorrow what your last state on this was | 21:22 |
| coreycb | cpaelzer: haven't done that before but will look into it | 21:26 |
| cpaelzer | thanks coreycb I'd appreciate that | 21:27 |
| cpaelzer | ok, cu tomorrow where I'll recheck the latest updates to that bug | 21:28 |
| evit | Silly question. I've updated my .bashrc to include my FQDN with /H but I don't see it upon logging back in. Any ideas? | 21:51 |
| evit | I mean \ | 21:52 |
| evit | \H sorry | 21:52 |
| lordcirth | evit, to include it in $PS1, you mean? | 21:52 |
| evit | lordcirth, Yes | 21:53 |
| lordcirth | evit, what line exactly did you put in .bashrc? | 21:53 |
| evit | PS1='${debian_chroot:+($debian_chroot)}\[\033[01;32m\]\u@\H\[\033[00m\]:\[\033[01;34m\]\w\[\033[00m\]\$ ' | 21:54 |
| evit | else | 21:54 |
| evit | PS1='${debian_chroot:+($debian_chroot)}\u@\H:\w\$ ' | 21:54 |
| evit | fi | 21:54 |
| evit | unset color_prompt force_color_prompt | 21:54 |
| evit | hostname produces www. Is there somewhere else I need to change that? | 21:55 |
| lordcirth | debian_chroot? | 22:00 |
| lordcirth | ah, nvrm | 22:00 |
