Is it worth repairing my broken Manjaro KDE, or shall I go for reinstall, without disturbing my documents in /home

Last week I moved from Xubuntu to Manjaro. My system has,

  1. Manjaro KDE Plasma with Timeshift, btrfs
  2. I have about 100+ gb of Documents folder, and would like them to be backed up periodically
  3. My partitions :
  • sda1 —> 300mb — FAT32 — /boot/efi
  • sda2 —> Balance (about 922.42GB) — BTRFS — Mounted on /, /home, /run/timeshift/backup, /var/cache, /var/log
  • sda3 —> 8.8GB — Swap

I would like to be able to restore Manjaro system files AS WELL AS documents in /home using Timeshift/btrfs. At present I do NOT take snapshots of /home

Today I messed up my Manjaro installation. And then I tried to restore to a timeshift snapshot. After restore, system takes about 15 minutes to boot with following errors.
Timed out waiting for device …
Dependency failed for /boot/efi
Dependency failed for …
Dependency failed for Local file Systems
You are in emergency mode …Give root password …

Even after difficult booting, system is very slow. I read somewhere that this problem is because of separate /boot.

I need help on following :

  1. Is it possible to easily recover my broken Manjaro installation?
  2. Is it possible to reinstall Manjaro KDE, without disturbing my documents in sda2 (/home)?
  3. What would be the best partitioning scheme for new installation?

Thank you.

Hi there. I can’t help you beyond saying that in such situations in the past, I have gone for a clean install. I prefer to start from scratch & tend to go with the default partitioning scheme suggested by the Manjaro installer. More power to you. Ruziel :slight_smile:

Last time I did a major upheaval, I simply copied my entire /home/ben directory, wiped it clean, then manually copied back what was needed - it’s cleaner that way (and you can leave behind any crud left behind from a year or two of removing software but not cleaning out the configs/caches).

Then I reinstalled and manually copied files back as I got it set up again.


Thank you and Ben. Does this also mean timeshift/btrfs is not a reliable snapshot? I have multiple snapshots of date/time when my system was fine. But when I restore to any of them, I remain saddled with broken system.

Or do I need other partitioning scheme for reliable timeshift snapshot?

And, if reinstallation is the only way to go, it is possible to reinstall Manjaro KDE without losing /home?

Link to a tutorial/step-by-step guide would help a new user like me. Thank you.

Assume your Manjaro is totaly broken ==> install new
First thing is to backup your HOME-Directory:

  1. every “not hidden” Files - like Downloads, Documents and so on
  2. all “hidden” files to a separate Directory
    mostly you will need .mozilla (Firefox) and .thunderbird (Thunderbird) after new install.
    you are advised to install/store the HOME-Directory on a separate partition or better Disk.
    The advantage: new install does not touch your home-directory any longer.
    You will need a live-medium on an USB-thumb-drive.
    Do the install in uefi-mode if possible.
    When the Installer asks what you want to do (partitioning)
    choose: “something different”
    For uefi you need one partition of ~200MiB ==> labeled “boot-efi” and formatted with fat32
    and on the same drive (hopefully a SSD-Drive) a partition called root ( / ), formatted with ext4
    Next: choose the home-drive or partition (e.g. sda1)
  • If allready exists /home on a separate partion ==> do not format this!! (use it instead)
  • You have to choose another name for your home-directory, because
    there may or will be broken configs. Use backup if necessary instead.
    Renaming the old /home before new install is a splendid good idea…
  • do not choose autologin at installation! If the KDE runs flawlessly, then you may choose Autologin…

Thank you. It is not totally broken. In about 15 minutes I am able to login to a working system which is very slow.

Does your suggestion give me RELIABLE and easily restorable snapshots of / and /home? How?

Look at: GitHub - teejee2008/timeshift: System restore tool for Linux. Creates filesystem snapshots using rsync+hardlinks, or BTRFS snapshots. Supports scheduled snapshots, multiple backup levels, and exclude filters. Snapshots can be restored while system is running or from Live CD/USB.
BTRFS - I knew this when using oepensuse long time ago
Has / is an automatic backupsystem, and Timeshift is the frontend in this case.
Some configs of XUbuntu are very very different from Manjaro - gives errors…
When I changed froim Ubuntu to Manjaro on some PCs - I had do create a new /home/user…
In your case, if you really cannot use a second SSD-Drive:
! After external backup !
new install ==> “something different”
==> sda1 keep and use
==> sda2 change to ~100 GiB and use as root ( / ) - format with btrfs
==> sda3 change to “rest of drive” ( - 10% free space approximately) and /home , format ext4
Use a swapfile - how to is described in manjaro or arch WIKIs.
Inside “Timeshift” -config there are filters…
EDIT: use the Timeshift version in Manjaro Unstable - there where errors in old version.

Haha forgot about the TEST user. If that works okay, then you know it’s your settings messed up - so you could just delete your .config file and copy stuff back from older snapshots.

try creating a new user, and if everything works with it, then there would be no need to reinstall …


Creating new user may not help, because getting to login screen itself is very difficult & time consuming.

May help, but:
his partition scheme is not really good - he will loose /home if the system crashes…

Ok, then reinstall - and then manually start copying from old Timeshift snapshots.

i see… so probably reinstall is the best option…

Looks like a broken /etc/fstab. Double check if UUIDs are correct. Also, what’s with those weird characters, is your tty drunk?

What partitioning scheme would be good for 1TB. I need reliable snapshot restoration. I read that timeshift/btrfs is good. But may be I made some mistake.

Normal partition scheme for 1TB:

1. 200 MiB fat32   ->    "boot/efi
2. 100 Gib btrfs   ->    /
3. about 800 GiB   ->    /home

Swapfile on /home - 8GiB sufficiant even if 64 GiB RAM

Ok, I will check on /etc/fstab after few hours and get back. I hope this may solve the issue. I am also confused about such characters.

(off topic!) Like current german politicans

Just confirmed that /etc/fstab is not broken. UUIDs are correct.

No idea then.

This would need thorough explanation and steps what you actually did or else we are just guessing. And if it’s timeshift’s fault, then search for similar issues and solutions if available. :man_shrugging:
Also those weird characters aren’t a good sign. Like some broken conf file or binary file being ran in tty which messes it.
