Authentication password failure

Support KDE Plasma
1

I have completed a fresh install of Manjaro KDE Plasma 21.0.7 on a desk top PC and in a separate SSD to the rest of my system. The bootable USB install went fine and booted for the first time post install with no issues. I opted not to password my login. When I went to install the many updates available I get an authentication error despite my password being 100% correct. I have reinstalled about 3 times changing my password but to no avail. I have searched for solutions in the forums but nothing quite adds up in my particular case. Any problem solving ideas would be gratefully received. I am no expert but have been using Linux Mint & various other distros from time to time and have never come across this exact issue before. I am using a USB keyboard and mouse and am certain the keystrokes are accurately reproduced.

Cheers

What’s your keyboard layout?

:+1: Welcome to Manjaro! :+1:

  1. Please read this:
    How to provide good information
    and post some more information so we can see what’s really going on. Now we know the symptom of the disease, but we need some more probing to know where the origin lies… :grin:
  2. An inxi --admin --verbosity=7 --filter --no-host --width would be the minimum required information for us to be able to help you. (Personally Identifiable Information like serial numbers and MAC addresses will be filtered out by the above command)
    Also, please copy-paste that output in-between 3 backticks ``` at the beginning and end of the code/text.

P.S. If you enter a bit more details in your profile, we can also see which Desktop Environment you’re using, which exact CPU/GPU or Kernel, … you have without typing it every time

I’m using standard US keyboard layout, thanks

I was thinking that you might picked UK layout or worse a Dvorak layout.

  1. You did try something simple like QWERTY, right?
  2. What are your keyboard settings in KDE and have you tried changing the model already?

Ah well attempted that but in order to save changes I need to enter a password, so…

There must be a stuck key / non-working key on your keyboard and as you’ve been reinstalling all the time anyway,

  • Reinstall
  • Take QWERTY / AZERTY / QWERTZ / …whatever is in the top row of your keyboard (and verify all these are working)
  • Note all the steps you take (screenshots of everything and save them to another USB than the USB you’re installing from
  • Post all screenshots if you would still run into the same issue.

:upside_down_face:

All good thanks, the QWERTY is working fine but given the OS is a bit unusable as is I will try another install - Cheers

I don’t know what else to say about this issue, other than it’s hugely frustrating. A reinstall just results in the exact same issue. I triple checked the keyboard selection.

I’m running Linux Mint installed a few months ago with the same USB keyboard and zero problems so to me this is a bug with the current install.

Unfortunately this might be a very short lived experience with this OS.

Evening where I am now and ended up installing Ubuntu after trying a different Manjaro flavour with exact same result. Ubuntu authentication on the same keyboard went without a hitch so sorry Manjaro but it’s farewell from me unless what is obviously a bug is sorted.

Thanks Fabby for the assistance,

All the best
David

Screenshot of your actual physical keyboard and your KDE keyboard settings?

We’re trying to help you, but as long as we don’t know where exactly the bug is, we won’t be able to correct it. If that is too much work for you: no hard feelings: at least you’re staying in the Linux family!

Full disclosure:* I bailed from Ubuntu ~3 years ago because I didn’t and still don’t like the way it’s progressing from an architectural POV.

(snap = crap, AUR= great!!!)

:grin: :wink:

Cheers for the feedback, it’s probably more a case of not having the time to keep going with it but if that changes I will have another crack at it. I agree that I would need to supply much more info and I want to acknowledge your generosity in being so willing to help chase down what was going on.

I will be keeping my membership here for now because I am bound to want to try Manjaro again😀

Meantime keep safe wherever you are,

David

A passwordless login is convenient - but it usually creates issues.

Don’t use passwordless login - it is bad practice - just as bad as using the phrase qwerty123 as password.
