(Solved) install fail-- loop0 mount failure
« on: October 10, 2017, 06:49:11 pm »
I am trying to install peppermint on a 120GB SSD.  Lubuntu is already installed and running perfectly.  When i boot from a USB, choosing "try before installing" or "install" both result in a mount failure something like, "mounting /dev/loop0 //filesystem.squashfs failed: no such device."  I've tried creating the USB memory stick with dd and lubuntu's startup disk creator.  One clue is that I cannot create it using unetbootin--- it tells me I have to mount the USB, even though it is already mounted.  So that may be a clue, but it doesn't help me.  One last clue--- I was able to install Peppermint on the exact same machine but on a HDD.  This seems strange to me because I can't even run Peppermint live off the USB stick--- not sure what the SSD has to do with it.     

Any help is greatly appreciated!  Thanks in advance!

Jim

Have you checked the MD5 hash of the ISO image to make sure it's not corrupt ?

I used the item on the boot menu that was something like "integrity check", but that was early in the process so I will double check.  I really appreciate your help!  One more clue--- I am having the exact same issue with LXLE (doing a little distro shopping)

Thanks again.

Here's how to use Unetbootin
https://forum.peppermintos.com/index.php/topic,5076.msg50704.html#msg50704

But i'd check the MD5 of the downloaded ISO image first.

If that doesn't work, what was the 'dd' command you used ?

Thanks again for the help. I'm still stuck.  Here's what I have tried:

1. I again downloaded Peppermint 64 bit and checked the md5 hash--- it was fine

2. I burned a USB drive using "sudo dd if=XXXXXXXX.iso of=/dev/sdb bs=4M"  This USB drive boots into the Peppermint installer just fine, but crashes when I try to install or use Peppermint live (same mounting error involving loop0)

3. I tried burning the USB drive using unetbootin and Lubuntu's disk creator and the same thing happened.

4. I found someone with almost the identical problem installing LXLE.  He/she issued the command "isohybrid XXXXXXX.iso" then used dd to burn a USB drive.  But when I do this, the problem persists.

5. Finally, I swapped out my SSD for a HDD and the problem goes away--- I can install either Peppermint or LXLE perfectly on my old HDD.  Strangely, unlike Peppermint and LXLE, Lubuntu installs perfectly on my SSD. 

I am now obsessed with this problem!  Any ideas?

Thanks again!

jim

Use GParted to copy the HDD installation to the SDD, then install GRUB.

Okay I'm thinking this is an SSD formatting (or partition scheme) issue.

Can you reinstall the SSD, boot to the LiveUSB, then post the output from:
Code: [Select]
sudo fdisk -l
and
Code: [Select]
sudo blkid
and
Code: [Select]
inxi -Fz



BTW, Peppermint ISO's are already isohybrid(ised) ;)

I reinstalled the SSD and executed the commands.  Note that I can't boot into Peppermint from the USB--- I can only get as far as the installation menu screen.  Here are the results of the commands:

So you can't even boot the LiveUSB if the SSD is fitted, but you can when an HDD is fitted in its place (same SATA port) ?

Yes, that's correct.  Weird, but correct.

I just double checked.  The machine boots into the Peppermint installer regardless of whether my HDD or SSD is installed.  But, non of the menu items on the Peppermint installer work when my SSD is installed--- fail with loop0 mount error.  When my  HDD is installed, all the menu items seem to work (e.g. I can run Peppermint live, start the installation, perform a disk check, etc.). 

Thanks again for your help!

Is the SATA mode set to AHCI in the BIOS ?

I just verified that the SATA mode is set to AHCI.  I'm afraid I don't know anything about BIOS setup so I can't tell whether the other settings are appropriate.

thanks

I forgot to mention one thing.  This is new install and so I have nothing on either drive that I can't lose.  So I'm open to reformatting, etc.  I'm just super curious as to what this is.

Thanks again

Do you know how to remove the "quiet splash" kernel boot parameters from the LiveUSB kernel boot line so we can get an idea what's going on in the background ?

Also does adding the "rootdelay=10" kernel boot parameter make any difference ?
