encrypted mint 17.2 xfce 64-bit: after pw at start-up for cryptsetup system start-up stops

Post by i_h_g_a_w » Thu Jun 21, 2018 2:45 pm

hi!
This is where I'm at, please help or hint. thx

preface: running on live usb, so I can't easily quote the exact error-messages or past wrong-doings (maybe someone lets me know how to do this anyhow).
tell me if you need more details.
I don't know if my problem is located at the "sda1 boot"-level or inside the "sda5 crypt-luks"
If there is a solved problem-topic (i couldn't find one) point me to it, please.

systemconfigs: see below
partitioning:
/dev/sda1 ext2 boot
/dev/sda2 extended
/dev/sda5 crypt-luks


introduction: i couldn't run any updates or fix broken packages for some time (virtualbox not running was an error i have been getting for some time) apt-get told me the directory was full (which it was)
every apt-get operation terminated along the line of

Code: Select all

"kernel 4.4.0-127 post-removal-scrip error on line 1"

I tried to rid my system of old kernels or packages manually, since any apt-get functions (i.e. autoclean, autoremove) didn't do a thing. once i had removed some (can't remember how...), i was able to update everything (no error about post removal script) - system seemed to be running just fine.

after reboot i was not able to start the OS up again, getting these messages (
i copied these error messages by hand, so they are aproximations):

Code: Select all

/script/local-top/scriptroot error on line 1 cannot open /dev/mapper/mint--vg-root no such file

Code: Select all

waiting for /dev/mapper/mint--vg-swap_1

Code: Select all

cryptsetup sda5 successfull (someweher alonge the line): "wait or press 'S' to skip or press 'M' for manual start-up

pressing either 'S' or 'M' doesn't prompt any reaction at all

also starting in recovery mode didn't do a thing as every option i choose just halted.


I've tried to come up with a solution (halfway I did in my first step removing stuff) by searching the web and the forums, but now I've conceded to not knowing what I was doing, hoping to get my data inside my encrypted volume back and the system running again.

Can I just do a new install trough the live-usb without destroying the encrypted volume?

thanks a lot
georg

"...just do a new install trough the live-usb without destroying the encrypted volume..." No, the installer will not re-use an old encrypted-OS, it will write over the LUKS header and your data will be gone for ever.

The 'Press S to skip' message is linux trying to mend a damaged file system. It usually manages that without help, or at least with minimum yes-no answers if something has to be deleted. You might leave it doing that for an hour, or overnight.

From a Live Session you can unlock the installed Mint, then duplicate what's intact before trying to repair it. If you need to do that, (-1) for not having a backup plan in action and look here... viewtopic.php?t=236864#p1261047 ...where an encrypted Mint is being accessed from outside.
Data stored in the volume will only be accessible with the correct password. If you lose this security key, all data will be lost.

Thanks a lot Mute Ant!
Leaving it run all night didn't help, so I'll go by unlocking the system manually from outside.
Will report about the outcome.

so, I was able to unlock the installed system.
questions remain:
1.- I found out I did have sort of a backup-plan, I had timeshift installed and running (which I forgot). Can it be of any use to me?
1.a - I tried running it but I got an error message: "Failed to mount devices"
2.- now, what?

thanks a lot

It seems like you might have an erroneous entry in fstab,

Boot the live media and enter

Code: Select all

sudo -i
/sbin/cryptsetup luksOpen /dev/sda5  sda5_crypt 
mount /dev/mapper/mint--vg-root /mnt
mount /dev/sda1 /mnt/boot
and paste back the results of these

Code: Select all

grep -v ^# /mnt/etc/fstab
blkid
df /mnt/boot

Nothing is glaringly wrong with your results.

With /dev/mapper/mint--vg-root mounted to /mnt what does df -h return.

Well, you're certainly not short of space so the only thing I can suggest is to try rebuilding the initram after doing an fsck on mint--vg-root and /boot

Reboot the live media and run sudo e2fsck -f -y -v -C 0 /dev/sda1

Then open the LUKS container with sudo /sbin/cryptsetup luksOpen /dev/sda5 sda5_crypt followed with sudo e2fsck -f -y -v -C 0 /dev/mapper/mint--vg-root

Then follow-up with

Code: Select all

sudo -i
mount /dev/mapper/mint--vg-root /mnt
mount /dev/sda1 /mnt/boot
mount -t proc none /mnt/proc
mount --rbind /sys /mnt/sys
mount --rbind /dev /mnt/dev
/usr/sbin/chroot /mnt /bin/bash
source /etc/profile
echo "nameserver 8.8.8.8" >> /etc/resolv.conf
export PS1="\[\033[1;33m\]chroot to ->\[\033[1;31m\](system) #\[\e[0m\] "
update-initramfs -u -k all
exit
Then reboot from the menu.

seemed to be working all fine until

mint / # export PS1="\[\033[1;33m\]chroot to ->\[\033[1;31m\](system) #\[\e[0m\] "
chroot to ->(system) # update-initramfs -u -k all

In your initial post you wrote
I tried to rid my system of old kernels or packages manually, since any apt-get functions (i.e. autoclean, autoremove) didn't do a thing.
so I'm guessing that you removed the /lib/modules/4.4.0-121-generic folder which is now causing the error attempting to rebuild the initrd for 4.4.0-121.

However it appears that the initrd.img-4.4.0-119-generic and initrd.img-4.4.0-109-generic completed OK.

Did you try booting to one of those :?:
