Oh No, It's "Oh No" now!

Which should actually work, because PureOS is 95% Debian.

That sounds good on paper. Tell it to the O/S - if one can get to it.

In short/long there is no online source with ideas to fix it that I was able to find.

Is there a way to re-install it without losing all the work I already put in to it?


If you can’t find a solution for your computer, you can try plug a live usb, decrypt and mount drive and save whatever configs to another drive then reinstall os to main drive. I would suggest checking out repairing instead though. Please upload some system logs so we can see some info. What packages were last modified and such.

Also what were you doing immediately before the error showed up?

No (as you might get there again), IMHO, just/perhaps using Terminal from time to time might help (perhaps another approach on how to upgrade usage applies: accustomed one instead of automated one).

Here just few good/useful (think about) tips:
sudo dpkg --configure -a

After Ethernet connection on (in Recovery mode, see below): “try this basic command to solve that problem”:
apt-get clean && apt-get update && apt-get upgrade -y && apt-get dist-upgrade -y
apt autoremove

and (as well) sudo apt-get remove gnome-shell … think of, related to gdm3 as well.

How to get there / how to start recovery: a. hold PowerOff button (if not using CTRL+ALTR+FX) and b. hit Esc several times after PowerOn (within few seconds, just as I recall now), this will get (allow to get) you (administrator) into Recovery Mode.

Share with us how you solved things, please, as it’s your turn now. It is nothing dramatic ( probably you’ve installed something that Gnome don’t like, therefore above error).

If you are looking for how to reboot the computer without holding down on the power button for 20 seconds, you can press CTRL+ALT+F1 (or F2, F3, F4, F5 or F6) to login a terminal with your normal user and password.

Then enter this command:
sudo reboot

If you just want to login again without rebooting, you can restart gdm:
sudo systemctl restart gdm


The directions I followed, in chronological order below:

Thank you. That’s what I needed.

I pushed the start button to boot the comp and went to the washroom and returned to see the error. No more details. You asked what I was doing. :slight_smile:

I will as soon as I can get to a command terminal prompt and look up how to grab them.

That was all very helpful - thank you. I waas able to poke around as per you suggestions and found the following:.


Viewing “System” from Advance mode I see:

"===  LVM State ===
Physical Volumes: not ok (BAD)

I have ordered a new HDD :sob:



If same happens again, please be aware of this command:
sudo dpkg-reconfigure gdm3

The command ‘dpkg-reconfigure gdm3’ will cause gdm to reload its configuration upon the next logout or reboot.

Furk. Unlucky dude. Make sure to make backups next time.

Thanks @Quarnero but the response is:
gdm.service is not active, cannot reload invoke-rc.d: initscript gdm3, action "reload" failed
I’ll just get a new HDD and start over.

The only thing lost is the time I spent on setting it up. I had copies of what was sort of needed. I never store anything important on anything connected to the 'net. The phone company doesn’t store my messages, I do. And comps, I disconnect the modem cables, copy data to wherever. Then disconnect from wherever and reconnect to the trashnet.

Thanks for empathy though, losing a HDD is hard to take.


Let me try again:
sudo dpkg-reconfigure gdm3
sudo reboot
sudo dpkg-reconfigure gdm3 (this one should be without any output).

Well, things got worse. The, when I rebooted started sounding like a grandfather clock. I’ve heard that before over the years. So, this morning, is put in a old HDD and reinstalled Pure over that. The knock at the door a while later was my 2 new 2Tb HDDs.

Before I remove the old HDD and start Pure install again a new 2TB, if I wanted to, is it easy (for me) to install Pure and Ubuntu, or any of he other ‘flavours’(?) lie Debian, Mint Pop_ etcetera?

Is it the same as setting dual boot with a Linux and Win 10? If it is, it’s not worth the effort.

I hope to have a desktop with Pure as main, then Ubuntu or Pop_OS as second on dual boot. Here is another, with 2nd 2Tb HDD I’d like to have Mint, or Debian and Win 10.
All the above would get their own 1Tb partition. I intend to have a 4th 4Tb HDD x 4 partitions as my dbase.

Please don’t go out of your way. Just asking if it’s possible and not too hard to do. I’ll look up how. All I found so far is ‘flavour’ dual with Win 10. Everything is dual with Win 10. Is dual boot Pure with Pop_OS duable?


Yes, keeping in mind that BIOS vs UEFI might complicate things, but other than that’s it’s fairly simple. A general rule of thumb is to install windows first and your “primary” OS last.

I guess I was not clear.

IF I use windows again, I’ll try a linux/Win boot maybe in the next decade.

For PureOS I’d create only three mandatory partitions: ef02 one (+32768), boot (+1048576) and home up to the half of the one of yours HDDs. Yet to tell Calamares that it should use three partitions as a whole (8300 for 2nd and 3rd one) we need to create fourth to reserve the space for the latter partitions. For first two I’d stay with gdisk /dev/sd[x] command, but for other two (before you click on Install PureOS icon) you might choose to use Gparted (search for Desktop icon) afterwards as somehow easier to find midpoint of your HDD (half of it for the first three partitions). You don’t need to necessary format fourth partition (don’t use it during PureOS install … just writing something that you know already), but creating it under GPT will expedite your next installation).

But before you start to install (might be related one of your posts here) check please the third partition with:
sudo parted /dev/sd[x]
(parted) align-check opt 3
3 aligned
(parted) q

As I find Debian-Installer up to the my taste I’d recommend to install Debian with non-free firmware as it will recognize all needed for your WS (so you can double-check PureOS non-free add-ons). Just after apt upgrade please execute apt full-upgrade as well. End this first boot (after installation) with apt autoremove and apt reboot. Third and fourth options for this BIOS MBR mode HDD perhaps might be Devuan (just because you asked) or How-to: Gentoo Linux from @lperkins2 (both are non-systemd).

For the second HDD with WIN10 (under UEFI mode) up front as @Gavaudan recommended (by planing to have /dev/sd[x]6, plus others, from the middle of HDD), the best option is to go with some other distributions, but if you want to make things as simple as possible (keep/make your PureOS user experience advanced than use the same Debian image as above linked or take Pop_OS (if @reC don’t mind). Also, Ubuntu was always very reliable distro (learned a lot from it, but after 14.04 LTS, or even earlier, I lost my contact with it completely).

Pop_OS is basically Ubuntu with some brandin’ and shit …

they did put some work on the lower levels with their hardware so i won’t say NO …

I was going to defend my reason for POP_OS but it turned out like a review. So I deleted it. But it did have some advantages I couldn’t find in Ubuntu. I’ve decided to leave the Win 10 1Tb HDD on it’s own. If there is a need for Win10, I’ll get there via Boot option. That process alone will act as a pleasant deterrent. So, Ubuntu it is! Plus, I am anxious to have one database for apps, and storage that each O/S can access each other’s -stuff- On a Intel yet (I hear that’s odd).

I haven’t figured out why yet.

What does the “[x]” mean above and will I be entering/typing in the following?

This means that you should replace [x] and type a, b or c. I made that so in order to avoid that user just copy/paste /dev/sda but actually wanted to work with /dev/sdb (or any other drive). Therefore I recommended (probably somewhere else) usage of sudo fdisk --list before starting to (re)partition some particular drive (especially when there exist more than one of them).
