I have an old desktop PC (64bit) and an old laptop (32bit), on each I have 2 Windows and at least 2 Linux distros .

At the moment I have Ubuntu 14.04.5 LTS Ubuntu 16.04.2 LTS installed.

After repartitioning the HDD and (or) Windows maintenance, I could only boot to windows.

So I've used a boot-repair stick to get the grub menu back.

The home and swap UUID became different from those listed in the fstab for one Ubuntu.

I can login to Ubuntu 14.04 but not to Ubuntu 16.04.

From Ubuntu 14.04 I created new partitions for home and swap for Ubuntu 16.04 and edited the fstab to contain the new UUID. But it didn't work, I can't login to Ubuntu 16.04.

It tries to login then comes back asking again for a password.

I have no Ubuntu 16.04 live CD. Please help me fixing that?

    fstab is for booting not login, are you having trouble booting or does it boot and you can't log in? – ravery Jun 29 '17 at 09:55
  • Have you tried a login in a tty or have you just tried the login from you xsession? – Ziazis Jun 29 '17 at 10:31

    Can you log in on a virtual console (Ctrl+Alt+F1)? – David Foerster Jun 29 '17 at 10:40

    Could that be a duplicate of https://askubuntu.com/questions/223501/ubuntu-gets-stuck-in-a-login-loop ? – variona Jun 29 '17 at 12:00
  • It boots till it reaches user name and password, I enter name and password it try log in but it comes back to user name and password, I use alt ctrl F1 to go to terminal and log in using name and password the type reboot. I used this command to edit fstab from the other ubuntu sudo -i

    mkdir /sparrow mount -t ext4 /dev/sda2 /sparrow

    gedit /sparrow/etc/fstab save it umount /sparrow

  • yes I can log in on a virtual console (Ctrl+Alt+F1) – abo sal Jun 29 '17 at 12:25
  • Please enter ls -lA and tell me the output for the file .Xauthority – variona Jun 29 '17 at 12:26
  • To me it sounds like your user doesn't have either a home or the rights to the home are not fitting to the user anymore. Since you said you recreated the home partition that would be my guess. – Ziazis Jun 29 '17 at 13:10
  • @ziazis as the OP can login from the virtual console, he seems to have a home. The symptom described looks to like the (already often asked) login loop problem. https://askubuntu.com/search?q=login+loop – variona Jun 29 '17 at 13:42
  • You can login into a virtual console even without a home, it will tell you /home/blabla not found opening instead, and still open a session. But his issue occurs exactly if the home is not reachable for the xsession. – Ziazis Jun 29 '17 at 13:45
  • @ziazis I guess you are right with "the rights ... are not fitting". Maybe using different userIDs for 14.04 and 16.04 Abo sal: "From Ubuntu 14.04 I created new partitions for home and swap for Ubuntu 16.04" – variona Jun 29 '17 at 13:48
  • my problem is that after partition modification of the HDD in windows the real UUID Using 'blkid' doesn't much the home UUID listed in the fstab. So I used the other ubuntu to creat the desired home and fstab using the method recomned by , Steve Stites in:

  • variona when typing ls – lA I get about 20 lines that starts with drwxrwxrwt or something tlike that I have 2 HDD ls -ld /tmp

    drwxrwxrwt 10 root root 4096 jun 29 16:36 instead of drwxrwxrwt 15 root root 4096 Nov 30 04:17 /tmp

  • @abosal the important thing here is if you have logged in from the virtual console into your account and you enter ls -lA do you see your directories and files AND do they belong to the user you logged in with: For example if I log in as variona a typical line would look like this: -rw------- 1 variona variona 1209 Jun 29 09:16 .Xauthority , meaning I have the right to read and write (rw) this file. – variona Jun 29 '17 at 14:19
  • @variona After copying the important data I intentionally deleted the old home and swap partitions (Ubuntu 16.04 ) to recover unused space at the end of the HDD, what is left is the /root partition. After boot-repair I used Ubuntu 14.04 to create new partitions for home and swap for Ubuntu 16.04, and modified the fsatb of Ubuntu 16.04, I used the comments of Steve Stites http://www.linuxquestions.org/questions/linux-hardware-18/mounting-question-631370/ I can log into gust account. when tryping sudo mv ~/.Xauthority ~/.Xauthority.backup I get:file or directory not found – abo sal Jun 29 '17 at 15:29
  • /home was on /dev/sda7 during installation

    #UUID=bf7235e3-c5d9-4961-9f93-b3caedf1cdb3 /home ext4 defaults 0 2 UUID=xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx /home ext4 defaults 0 2 after delteing /home partition UUID=bf7235e3-c5d9-4961-9f93-b3caedf1cdb3 does not exit using geparted I created new /home UUID=xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
