| crystal_water | Hello | 07:36 |
|---|---|---|
| crystal_water | I have updated lubuntu 19.10 tot lubuntu 20.04 but in the upgrade process my machine lost power and now can i not boot my machine to lubuntu. how can i fix this problem | 07:38 |
| apt-ghetto | crystal_water: What do you mean with "cannot boot"? | 07:53 |
| crystal_water | if i will start up my machine to boot i get a error machine after typing in the grub passwaord | 07:54 |
| apt-ghetto | You have an encrypted installation? | 07:55 |
| crystal_water | yes | 07:55 |
| crystal_water | with the standard tool in the lubuntu setup | 07:55 |
| apt-ghetto | You can start a livesystem and then chroot into the installed system | 07:56 |
| crystal_water | i have now boot in a livestystem of lubuntu 20.04. what's the next step? | 07:56 |
| apt-ghetto | UEFI or BIOS? | 07:57 |
| crystal_water | BIOS i think | 07:58 |
| mikecool818 | well i used Rufus in ISO mode to boot up an Pentium 4 pc | 07:58 |
| mikecool818 | lubuntu boots up, goes through the pre-installation hoops | 07:58 |
| mikecool818 | and its stuck right after the Scanning CD/ROM | 07:59 |
| mikecool818 | what could be the issue for the screen not showing up anything after that | 07:59 |
| mikecool818 | i tried to set the kernel to nomodeset. idk what it does but it didnt help | 08:00 |
| mikecool818 | so..could it be that after scanning CD/ROM (boot media) part, the blue screen staring at me.. | 08:00 |
| mikecool818 | ...could sparkle up with further steps after waiting for like 15 mins.. | 08:01 |
| mikecool818 | thanks | 08:01 |
| apt-ghetto | crystal_water: Open a terminal and type: `sudo cryptsetup luksOpen /dev/sdXY cryptlvm` | 08:01 |
| crystal_water | in the livesystem? | 08:01 |
| mikecool818 | yes sir | 08:01 |
| mikecool818 | live USB boot | 08:01 |
| apt-ghetto | crystal_water: yes, from the livesystem | 08:02 |
| mikecool818 | ah | 08:02 |
| crystal_water | Miecool818: i have i to apt-ghetto | 08:02 |
| apt-ghetto | crystal_water: After opening your encrypted device, you mount the installation `sudo mount /dev/mapper/luks-<UUID> /mnt | 08:04 |
| crystal_water | apt-ghetto: i have put the exact code in the terminal and the output is : Device /dev/sdXY doesn't exist or acces denied. | 08:04 |
| apt-ghetto | crystal_water: Well, for X you should use the name of the disk and for the Y the number of the partition, in your system it should look like sda1 or sda5 or whatever | 08:06 |
| crystal_water | i will try that | 08:06 |
| apt-ghetto | crystal_water: Check with `lsblk -f` | 08:06 |
| apt-ghetto | crystal_water: In the FSTYPE column of lsblk you should see "crypt_" | 08:08 |
| crystal_water | and copy the ' sum' after crypto? | 08:09 |
| crystal_water | it say that it is already mapped or mounted | 08:09 |
| apt-ghetto | What is the mountpoint? | 08:10 |
| crystal_water | i have solved it. i had the file manager open en decrypt there | 08:11 |
| apt-ghetto | crystal_water: What is the mountpoint of your luks device? | 08:14 |
| crystal_water | i get the error again. i have sda-sda1 crypto. and use sda1 or sda1 cypto and give the same error: Cannot use device /dev.sda1 which is in use (already mapped or mounted) | 08:15 |
| crystal_water | with lsblk -f i see no device with the name luks | 08:15 |
| crystal_water | yes now i see it | 08:16 |
| apt-ghetto | Ok, then do: `sudo umount /dev/sda1` | 08:16 |
| crystal_water | it is onder sda1 | 08:16 |
| apt-ghetto | And after that remount it with `sudo mount /dev/mapper/luks` press TAB to autocomplete and then ENTER | 08:17 |
| apt-ghetto | Sorry, I mean `sudo mount dev/mapper/luks-..... /mnt` | 08:17 |
| crystal_water | i say that it is not mounted and after i will decrypt the device i say it is mounted or mapped | 08:18 |
| apt-ghetto | Which command did you type? | 08:19 |
| crystal_water | for unmount (sudo umount /dev/sda1) and for decrypt (sudo cryptsetup luksOpen /dev/sda1 crypto cryptlvm) | 08:20 |
| apt-ghetto | cryptsetup luksOpen is not necessary | 08:21 |
| apt-ghetto | You have to mount it to /mnt, so that we can prepare the chroot | 08:21 |
| crystal_water | i take now a break i will comeback soon | 08:21 |
| crystal-water | i am back from the break. What is the command to mount sda1 to /mnt? | 09:08 |
| apt-ghetto | crystal-water: sudo mount /dev/mapper/luks-.... /mnt | 09:12 |
| apt-ghetto | You can press TAB for the autocompletion | 09:12 |
| crystal-water | at the dots i need to type sda1? | 09:13 |
| apt-ghetto | no, `ls -l /dev/mapper/` shows you one device | 09:14 |
| apt-ghetto | It is a unique identifier | 09:14 |
| crystal-water | do i need root root 10 or root root? | 09:15 |
| apt-ghetto | no, just start typing and when you wrote luks- press TAB once or twice | 09:15 |
| crystal-water | ok i will do that | 09:15 |
| crystal-water | tab do nothing | 09:16 |
| apt-ghetto | then check it with ls -l /dev/mapper and write it. The command will then look like sudo mount /dev/mapper/luks-5abc4532-9229-a03a-29299302902 /mnt <= just an example | 09:19 |
| crystal-water | if i do -l /dev/mapper i get no output that looks like 5abc4532-9229-a03a-29299302902 | 09:21 |
| apt-ghetto | Did you reboot the live system? | 09:21 |
| crystal-water | no i have not reboot wil i was on this irc | 09:22 |
| apt-ghetto | Do you see control and something else? | 09:23 |
| crystal-water | yes by crw------- 1 root root 10 | 09:24 |
| crystal-water | and there under i see cryptlvm -> .. dm-0 | 09:25 |
| apt-ghetto | Ahh, okay, then use sudo mount /dev/mapper/cryptlvm /mnt | 09:25 |
| crystal-water | that works but i see nothing | 09:26 |
| apt-ghetto | That is good | 09:26 |
| apt-ghetto | then we continue: sudo mount -o bind /dev /mnt/dev | 09:27 |
| apt-ghetto | sudo mount -o bind /sys /mnt/sys | 09:27 |
| apt-ghetto | sudo mount -t proc /proc /mnt/proc | 09:27 |
| apt-ghetto | sudo cp /proc/mounts /mnt/etc/mtab | 09:27 |
| apt-ghetto | sudo chroot /mnt /bin/bash | 09:27 |
| apt-ghetto | Execute line by line and after that you are in your installed system | 09:28 |
| crystal-water | by the thirth from above comammand i get ( cp: '/proc/mounts' and '/mnt/etc/mtab' are the same file' | 09:29 |
| apt-ghetto | Yes, no problem, you can continue | 09:29 |
| crystal-water | i have typed the command's in the live system. | 09:30 |
| apt-ghetto | The command prompt has changed? | 09:31 |
| apt-ghetto | Then you can execute: apt update | 09:31 |
| crystal-water | yes to root@lubuntu instead of green lubuntu@lubuntu | 09:31 |
| crystal-water | update is now ready | 09:32 |
| apt-ghetto | in the output of apt update you should see the word focal? | 09:32 |
| crystal-water | yes the files that are donwloaded' | 09:32 |
| apt-ghetto | then do: apt full-upgrade | 09:33 |
| apt-ghetto | The Lubuntu installation was a fresh installation with 19.10? | 09:33 |
| crystal-water | i get a error that i need to execute 'sudo dpkg --configure -a' to solve the problems | 09:34 |
| apt-ghetto | Good, do that: dpkg --configure -a | 09:34 |
| crystal-water | woth sudo? | 09:35 |
| apt-ghetto | You are root in the chroot, so you do not need sudo | 09:35 |
| crystal-water | if it is a fresh install i need to make a back up first? | 09:35 |
| apt-ghetto | If your data are important for you, you always need to have at least one backup | 09:36 |
| apt-ghetto | If you don't care, than you don't need a backup | 09:36 |
| crystal-water | than i will make a back up now. i will take a couple of minutes' | 09:37 |
| apt-ghetto | I go offline in a few minutes | 09:37 |
| apt-ghetto | But now you have the steps to chroot into your installation | 09:37 |
| apt-ghetto | And if you need help, there are certainly other people here, who can help you | 09:38 |
| crystal-water | oke then i will ask a nother person. | 09:38 |
| apt-ghetto | Can you please tell me, which was the original Lubuntu installation? 18.10? 19.04? 19.10? | 09:38 |
| crystal-water | thanks for all the help it is very usefull and i takes a lot of to search on the web | 09:39 |
| crystal-water | 19.10 | 09:39 |
| apt-ghetto | That is good | 09:39 |
| InHoooman | guys. quick question. anyone knows if you can change the keyboard layout on a bootable usb installation? | 09:40 |
| apt-ghetto | InHoooman: If you have a GUI, then `setxkbmap it` would change it to the italian keyboard layout | 09:40 |
| crystal-water | now i can't see the the hard drive in my machine now is it because if have mounted it with my live systems? | 09:41 |
| apt-ghetto | crystal-water: You should see it under /mnt with pcmanfm-qt | 09:42 |
| InHoooman | thanks. i guess i'll need a keybind to change between the two layouts. thanks | 09:42 |
| InHoooman | thanks again* | 09:42 |
| crystal-water | apt-ghetto and after that remount it for the fresh install? | 09:42 |
| apt-ghetto | InHoooman: It depends, if you are talking about a live system or about an installed system | 09:42 |
| apt-ghetto | crystal-water: If you have your backup, then you should try to reinstall Grub inside the chroot with: grub-install /dev/sda && update-grub | 09:43 |
| apt-ghetto | crystal-water: And you should try to fix the dpkg errors, so you don't need to reinstall the system | 09:44 |
