Remove 2.8 and dual boot 3.4 with Ubuntu

[gold_finger]

In the ll3.4 when opening with e and erasing ro splash quiet $ vt-handoff and adding rw init=/bin/bash
after unable to use password went back to where I made the change and ro splash quiet $ vt-handoff was in the edit of ll3.4

Pressing "e" to edit grub options only affects current boot, it's not permanently changing things.  So, yes on subsequent boot you will see "ro quiet splash vt.handoff" again and not the edit you did before.


As I understand things now, you can boot into Ubuntu, have choice shown for LL3.4 and choice for LL2.8 is gone, but you can't boot into LL3.4 because it says your password is invalid.  Is that correct?


If so, honestly I'm stumped.  Changing/Resetting password with tutorial I referenced should have worked.  I'm not sure why it didn't and don't really know where to go from here.  Maybe Jerry (or someone else) will see this and have a different idea on how to get things working.


P.s.
Could you elaborate a bit more on this quote from yesterday?  I'm not sure I understood it correctly:

I booted ll-3.4 and now was getting to update and use synaptic
But I no longer have a valid password

Were you saying that you were able to boot into LL3.4, but that your password didn't work when you tried to run updates and/or Synaptic?  Or were you saying you couldn't boot into LL3.4 at all?

The password that I was using on 2.8 does not work on 3.4

Anyone else have any suggestions on how to reset password on LL3.4
Have tried two simular programs neither one worked
I can boot LL3.4 but I can not enter a valid password for programs that need same

If LL is installed you can try (if you haven't yet) https://www.freecinema2022.gq/manual/insta...espassword

If you're in a Live Environment (booting from USB/DVD) - username is linux - password is blank/empty


**Update**
Sorry does look like you tried the link.. only other advice, as mentioned - make sure caps/num lock aren't enabled (verify by typing password in username field)...
- or make sure you typed "sync" and "reboot -f" in the script....

Tried both reset password programs..The only difference is one spells passwd and the other spells password

If link to LL help manual posted by firenice03 is the "program" you were referring to a few posts back, I just had a look at it and it is the exact same procedure for resetting password as my tutorial on Mint forums.  Both use command passwd, not password -- so don't know where you saw that.  (If firenice03's link is not what you were referring to, please post a link to program you found and are talking about.)


In any case, that procedure should have worked to reset your password.  Try again, but this time for test purposes, reset to a simple password (eg. something using only letters and numbers, no special characters or spaces) and see if that works.


Question:  is the password you're using in Ubuntu the same as one you're trying to setup in LL?  If not, try setting LL password to same one you're using in Ubuntu.

Hello,

I am unsure if it will work with LL, I have only done it on Debian for Raspberry Pi, it may differ you can either try it experimentally, or await confirmation from the experienced users.
I have never tried just jumping to #9 below but it may be worth trying this when at the root prompt as per manual to change your passwd and see if this solves it first.

Method

Follow manual until "at the prompt enter passwd"

1- Instead at this prompt enter

Code:

adduser phil66

(or any username other than your existing one)

2 - enter your new simple as [member=16]gold_finger[/member] previously wrote not using any special characters, and (not previously used/tried) passwd, when prompted to retype, retype this new passwd.

3 - when prompted is it correct y/n, click y

4 - at the same root prompt then enter

Code:

adduser phil66 sudo

await confirmation to appear.

5 - at prompt enter

Code:

exit

6 - on reboot enter your new login phil66 and the passwd you chose at #2 above.

7 - you will have a new home folder under the new name, it will not contain data files like music for example in your old folder, you may be able to change the old username password using menu gui then copy those off to a media such as usb.

8 - when you are satisfied you have saved any data file from the old home folder, *Warning - if your Ubuntu home folder is not the same name*, then you can delete it by deleting that user.
Open terminal from desktop, login as the new user eg; phil66 and enter into terminal

Code:

sudo deluser type-old-username-here

when confirmed user deleted, then type

9 -

Code:

sudo passwd root

when prompted enter you new more complex passwd (to replace the passwd chosen at #2 above), and retype it when prompted. Wait for text "passwd: password updated successfully"

Close terminal by typing

Code:

exit

Do not reboot yet.

10 - open terminal again, and type

Code:

sudo -i

enter your new complex passwd (chosen at #9 above), when prompted, if this works, just type

Code:

exit

your done ?

Well this procedure did not work. It went and locked up the program midway through the procedure
I wish I could tell more but it simply did not work

Hello phil66,

by program do you mean the "terminal",  or are you trying this in something else ?
You can access the terminal from your desktop by holding down the Ctrl key and Alt Key then press t (Ctrl+Alt+t) on your keyboard.

If using terminal at which number of the procedure did it lock up the terminal ?

[phil66]

I am running from the help manual program reset password
It advances thru the steps and goes into your suggestion until it reaches line 5 exit
At this time it locks up the program

[bitsnpcs]

Can you try it using the terminal, hold down Ctrl and Alt key and press t, to open it.

Begin with

Code:

sudo -i

then follow from step #1.
