    Are you using AppArmor or SELinux?

    Re: Why is this failing?

    Neither one. Not even sure what they are.

    Running Ubuntu 20.04LTS with the X-Windows overlay (It boots up as "Xubuntu"). It was an upgrade from 18.04 and originally 14.04. I have a feeling this would all go away if I reinstalled a fresh copy of 20.04 and overwrote the disk. However, I have a LOT of applications, most of which I wrote myself, and hate to have to recreate them.

    Re: Why is this failing?

    See what
    Code:
    getent group | grep 124
    shows for the group.

    What does getfacl show for /home/bill?

    Also what is the file system's mount situation,
    look at what
    Code:
    mount | grep /dev/sdb1
    shows
    Splat Double Splat Triple Splat

    Don't mind me, I'm only passing through.

    Re: Why is this failing?

    getent group, with a grep for "124", returns nothing. Without the grep, the list shows no entry for "124".


    And the mount situation is:

    Code:
    bill@bill-UBU:~$ mount | grep /dev/sdb1
    /dev/sdb1 on / type ext4 (rw,relatime,errors=remount-ro)
    bill@bill-UBU:~$

    Re: Why is this failing?

    I've created a group named x124 with a GID of 124 and put my username (bill) into it. Now the results of the 'getent group' command is:

    Code:
    bill@bill-UBU:~$ getent group | grep 124
    x124:x:124:bill
    bill@bill-UBU:~$
    Does this help me in any way, or has it muddied the waters? I can delete the group if necessary.

    getfacl /
    getfacl /home

    Sorry. Was out of the house mowing lawn.

    results of those three commands:

    Code:
    bill@bill-UBU:~$ getfacl /

    Re: Why is this failing?

    ACLs are probably not the problem since they always correspond to the permission bits (see "man 5 acl", section "CORRESPONDENCE BETWEEN ACL ENTRIES AND FILE PERMISSION BITS"). In general ACLs are used to grant additional permissions to user(s), they can't be used to take permissions away.
    One possible reason might be an error in the file system which has led to the fs being remounted read-only. Try booting from a live USB and running fsck on the file system.
    Another possibility are attributes, specifically the "immutable"attribute (which does just what the name implies). Use lsattr to see what - if any - attributes are set for the directory and the file in it.

    Re: Why is this failing?

    A few days ago, I booted into a live DVD and tried just that. I was unable to mount the drive. No matter what I tried, it failed. I tried several methods which I found in various Linux forums, but none worked. I was probably doing it wrong because the error referred to "mount point" being incorrect. I've never mounted a drive/partition manually. They were either plugged-in USB drives or were SATA drives installed internally and picked up on boot by the OS.

    I suppose if absolutely necessary, I could unship the drive from one computer, hook it to a SATA to USB dongle, and plug it into another of my Ubuntu machines. I hope this doesn't matter, but the system is dual-boot with Windows 7 on one physical drive, and Ubuntu on a different physical drive.
