Help with issues regarding installation of Debian

Error in upgrade process might make a server unbootable

Postby no2systemd » 2018-12-19 20:45

I am completely new to Debian and have found myself in the Alice in Wonderland environment today. Can somebody please explain me what to do after I uncounted the error today which might lead to errors in grub.cfg: some symlinks were created by apt in the root filesystem, from /boot, the situation I never experienced before.

I am trying to move some servers from RHEL to Debian and I already have one server (which was created by a different sysadmin, who left). Initially it was version 8 (Jessie)
It has dual boot (CentOS/Debian) configuration.

Today I tried to upgrade it from 8 to 9 (Stretch) to install Docker on it (I was not able to install it on Jessie due to dependencies for package
software-properties-common

Actually it did not help and the problem remains after the upgrade

You are about to do something potentially harmful.
To continue type in the phrase 'Yes, do as I say!'

Initially on Jesse I answered yes and it happily deleted apt. It took me some time to find solution but eventually I reinstalled apt but as I have found later not app-utils ;-)

Now returning to the upgrade. When I typed

Code: Select all
apt dist-upgrade


apt initially did not find package

Code: Select all
Get:1 http://security.debian.org/ stable/updates/main linux-image-4.9.0-8-amd64 amd64 4.9.110-3+deb9u6 [39.0 MB]


So I run it with -m switch to skip the package which I planned to download and install separately as I thought that those were patches. It did not work well as after that update version is displayed as:

Code: Select all
root@euler:/etc/apt# cat /etc/*release

Re: Error in upgrade process might make a server unbootable

I already have one server (which was created by a different sysadmin, who left)
...


You need help, this person would be the one to call? Ask where the automatic daily backup is and how to get it restored. I can't believe you'd jump into this, and during the holidays, wow...

I agree
That system is ripe with issues
and should not be messed with by a Debian novice..... at any time of year....
lots of issues that can frustrate - Advanced Debain Admins
especially if the goal is to just_say_no_2_systemd


edit: jessie, in my opinion is "The most sysV unfriendly version of Debian"
followed very closely by Stretch!

I don't even understand what the problem is.
You want to upgrade to stretch?
clean up sources.list and sources.list.d anyway. It's a mess.

for stretch, with superfluous lines for src:
https://wiki.debian.org/SourcesList#Exa ... urces.list

Read (at least) the upgrading chapter of the <release notes> http://deb.li/OFVv . In /etc/apt/sources.list, change "jessie" to "stretch" and remove stable-specific lines like jessie-backports. apt-get update && apt-get dist-upgrade. 3rd party repos like <dmo> are known to cause problems with the upgrade.

What guide were you following to upgrade from Debian 8 to 9? It sure doesn't look like the Debian one.

https://www.debian.org/releases/stable/ ... ading.html
The MX Linux repositories: Backports galore! If we don't have something, just ask and we'll try--we like challenges. New packages: Flightgear 2018.2.2, 4.19.13 kernel, wine-staging 4.0~rc4, Stellarium 0.18.3, VLC 3.0.5, Midori 7.0

Thank for your reply and the attempt to help. It is much appreciated.

This is a research server, all valuable data are on special storage system. I have a backup, but as I do not know Debian I am reluctant to reinstall the server.

If the previous admin kept the server systemd free (by using sysvinit instead of systemd ) the upgrade path to stretch is not supported.
The colored files and directories in / ( I posted above ) were created by someone and are not normal defaults.
Find out what is in them .... so you will know what the previous admin is talking about when you contact that person.

I sure can understand.
In general, the most cases, installing debian is pretty straight forward.
The package-manager too, and it is quite robust, as long you don't add third party repos or apps or such.
Won't help you much that it's straight forward in general, if you are the one for whom it isn't ... (but cleaning up the mess sure seems more difficult. way more difficult, imho).

I'd do a few test installations somewhere, to get the hang of it (assuming you want to do it at all).

lliv: i wouldn't bet, but i think jessie still used sysv, and systemd is default since the actual stable, aka stretch?

Wheezy introduced systemd and that is why LTS was conceived.
Jessy got aggressive about systemd defaults....
Stretch continues systemd dependencies throughout the packaging system that required serious non-default adjustments to run with sysvinit.
Buster is better than stretch for running sysvinit
Sid is better than buster by a hair presently.

I had to hold the xserver-stack in sid to the wheezy version all through the jessie release cycle and part of the stretch cycle if I wanted to run sysvinit in sid. 44 packages held in all by the time I was able to dist-upgrade sid again. iirc ( and it wasn't all that long ago when I finally could upgrade everything in sid again.
I broke sid a few times testing to see if I could upgrade the xserver-stack of packages ..
not fun holding old packages of dbus, libaudit0, udev, xserver-xorg-*, libgl1-mesa-glx, libpam-policykit, passwd, login, and their deps.
Try it sometime - you'll see just how straight forward it is.

Re: Error in upgrade process might make a server unbootable

add to that mess the fact that no2systemd's server has nfs and "some kind" of multidisk virtualization listed in the fdisk -l output
plus the stuff the old admin left in the root directory
to upgrade it would be advisable to take it offline and not expect to put it back in service with the same behavior as it had in the past.
reconfiguring every serverside function that refuses to reconnect.

I was going to suggest that to @no2systemd as well.
I didn't suggest it previously because I understand the possible pitfalls that can occur when dist-upgrading a server showing some of the complications already visible..

A dual boot CentOS/Debian!
which one controls bootup?
why is it dual boot?
what is debian used for?
what is centos used for?
etc.

Re: Error in upgrade process might make a server unbootable

Thanks everybody, especially xepan who really helped with the strange for me issue of not matching the apt configuration and version. In RHEL yum repositories are ungraded with the version; in Debian this should be done manually, so actually this is a normal situation after that upgrade.

> clean up sources.list and sources.list.d anyway. It's a mess.

Done.

Many people pointed out that things here are disorganized and I was not prepared to the task in hand, which is true :-). But (1) this is not a production server, and (2) we need to fight with the army we have, not with the army we wish. I am the only guy who is interesting in moving some servers to Debian (installed without systemd) here. I feel that with RHEL7 and IBM acquisition of Red Hat creates some openings for Debian in the enterprise environment as it is the only major disro that can be run without systemd. Creation of Debian based Docker images on this server might be a good demo, because it allows to run Debian compiled application on RHEL using container.

But after some thinking I am not sure that switching to the kernel 4.9 (used in Stretch) is a good idea. RHEL 7.4 uses 3.10.0 ( I think), so it might well be that for really complex applications Jessie with its kernel 3.16 is a better fit.

Another problem is that this server does not have Drac, and I am remote. That's why I am interested in the question whether it will reboot, as I still want to explore it further (and today I finally managed to install Docker on it). This only "semi-official" Debian server on real hardware available for me. Otherwise this server is just for researchers who run open source developed on Debian and it is used sporadically, may be once a month for week or so. So a week downtime will not bother anybody too much.

This was also the first installation of Debian for the sysadmin who left (he uses Arch at home and CentOS/RHEL at work), so he is on no help. He was not sure that he will succeed, and that's why he preserved the old CentOS and created dual boot. Which now complicates things. I probably will wipe out CentOS, if the server not reboot. In this case I will mainly need a backup of /etc.

So I have one more narrow question: Will server reboot with the current grub.cfg. I am mostly working on old versions of RHEL with the old grub and good old init. So this is like Chinese to me (BTW this install does use systemd so the upgrade from Jesse to Stretch was legit).

Looks like it will, as those misplaced symlinks are not used anywhere in grub.cfg, but I would like to hear the opinion of a more knowledgeable folk.

After fixing apt sources.list file (the dir sources.list.d was not screwed up) and running apt upgrade I did not find problems with packages via dpkt -C

Here are the two entries extracted from grub.cfg with most leading blanks removed.
