cannot find UUID

[Trapster]

Yesterday I downloaded and successfully did a frugal install to play with easyos.
Everything booted fine, had sound, wifi, etc...
I went to reboot easyos and I got the 'cannot find UUID'
I have this frugal install on sda2 with 12 other puppy and pupdog frugal installs.
Now, they all give me the cannot find UUID when booting into ANY of them.
I can boot into a separate usb stick and check the UUID. All the grub entries have the correct UUID from blkid.

How do I fix this?
Help.

Added: I use a full install of antix on sda1 to boot from.
The frugal install is using easy-4.3.5-x86.img

[williwaw]

can you provide some more detail about the step you took to make the install?
can you describe what you see just before the error message, maybe a pic?
can you see the other frugal install folders if you boot into antiX and then plug in and look at your USB drive?

[Trapster]

I did the frugal install my normal way, Extracted the 3 files from the image file and put them in a folder. I added the boot stanzas to grub and everything booted fine.

I can't remember the exact message when booting. Something to the effect of "cannot find UUID, device does not exist"

This happens now on all my frugal installs since the reboot. Is this related to easyos being encrypted?
Everything looks normal with sda2 with gparted.
Yes, when in antix, I can see everything. The only thing that seems weird is that I cannot unmount sda2 when booting from sda1. Something about /proc/2524/exe is in use (?)
Since something is effecting all my frugal boots, I assume it's drive/partition related?

It looks like you have a too-old version of grub, that does not support ext4 encryption. This page explains:

https://easyos.org/install/easy-frugal- ... ation.html

Quoting:

Problem with old GRUB versions:
GRUB v1, GRUB4DOS, and GRUB v2 prior to version 2.0.4 (released 2019), do not recognise an ext4 filesystem if it has modern features such as the "encrypt" feature turned on. You can still use them; however, the feature of EasyOS to encrypt some folders in the working-partition will not be available. Folder encryption is a security protection if someone steals your computer, or whatever media EasyOS is installed on. You will have to forego that extra protection.

If this is your situation, you either have to update grub, or revert ext4 to not have encryption feature enabled.

The latter is easier said than done. Easy to enable it:

Code: Select all

# tune2fs -O encrypt /dev/<partition>

...however, tune2fs cannot turn encrypt off.

Can't recall how to turn it off. Quick search, yes, need to use debugfs:

Updating grub to 2.06 fixed the issue.

I downloaded and compiled 2.06.
My issue now is update-grub is looking for files in /usr/local/etc/grub.d instead of /etc/grub.d
Should I have done something different with ./configure or make?
I am temporarily using symlinks until I figure that one out.

Regardless, I am now able to boot into my other frugal installs.

Thanks!

Yes, you should always do this:

Code: Select all

# ./configure --prefix=/usr --sysconfdir=/etc --localstatedir=/var

[Trapster]

That did it, thanks!
