[@kevinklement2621]

I like that you pronounce it "f-stab" like I always do in my mind. I have no idea how long it was until I realized it was "f.s.-tab" for "file system table".

[@ChrisTitusTech]

Hahaha, this is good info. I haven't thought to call it F.S. tab but you are right!

[@digitalsparky]

@@ChrisTitusTech yeah, i used to call it f-stab too... then i realised mtab also existed (mount tab) ... so realised it was fs-tab.... though just put some lettuce around and caesar would definitely call it f-stab... coz... caesar salad....

[@StefanoPapaleo-TS]

Don't ever take a test to see if you possess the traits of a serial killer, guys - your mindset on fstab speaks volumes :)))) jk!

[@digitalsparky]

It should be noted with chroot that if you're doing upgrade fixes and stuff you may need access to devices, in this case you will need to bind mount (mount --bind) /proc and /dev into the chroot environment first, failure to do so may come up with errors)

[@gnarlin4964]

I learned this back in the day when I used Gentoo. You have to bind /dev and /proc to do the gentoo chroot for install. Best to always do it.

one time Xorg got deleted and I could not figure out why lightdm wouldn't work

[@frclayton]

Very nice. Few weeks ago I deleted my boot partition by accident, had to remember manual commands for partition creation, format, etc. I suggest a presentation for a disaster recovery when you disk has to be replaced and you need your OS back. What are the best tools, procedures, etc. for this kind of situation?

[@reinerwilhelms-tricarico344]

Another question, where things seem to be completely different in Ubuntu. I am now on version 22.04. It’s 2024, and the file /etc/fstab is dated May 2017. Why is that never changed? I did several complete system upgrades since then.

For Debian-based, just use *boot-repair* if the issue is a GRUB issue (via a Live Session).

[@vreauacaunt]

Had this problem yesterday and boot-repair helped ))

[@johnmal5975]

I also go into advance options on grub menu and choose repair packages. Usually works great. Having a copy of boot repair is a necessity!

[@gnarlin4964]

I didn't find boot-repair in the Ubuntu main depo. Apparently it's a ppa? Why hasn't it been merged into debian main? Looks like a really useful tool to have there? Edit: found this: www.howtogeek.com/114884/how-to-repair-grub2-when-ubuntu-wont-boot/

@Chris Titus Tech Is there a way to make a bootable usb on Windows 10 using a Command line like you did in linux? Rufus doesn't work right and etcher on my Win10 has destroyed 3 usb sticks for some reason. Bricks them every time so I have been forced to go old school and burn iso to dvd. USB would be so much faster.

[@tsundoku5733]

12:06 This is why some people say that dd stands for "disk destroyer". By the way, you can add the option status=progress to see a progress indicator.

To paraphrase the Genie from the 1991 movie "Bernard and the Genie": Type the command "dd" with the caution you would normally reserve for "Please, castrate me".

[@nishantt.8717]

I used dd to create bootable pendrive. I typed correct device name of drive. But it wont boot up. So I boot my linux and try to install gnome disk utility, and it asked passwd.

[@rgyver2835]

i want to ask if you could include in a video, what to do or how to find what to install after an update makes a hardware component stop working. I have Linux Mint 19.2 running on a Dell Chromebook 13 7310. After installing a long list of updates, my touchpad stopped working upon reboot. Being fairly new to Linux, i had not a clue as to how to determine what caused it. Coming from windows, i though i just need to reinstall the drive which in Linux would be a package. But knowing what package even where to find the right package, i was completely lost. I did verify that it was enabled, and ran command, cat /proc/bus/input/devices, to verify that it still saw the touchpad device. i was able to fix it by using timeshift and then determined that the kernel update (4.15.0-54-generic to 4.15.0-72.81) was the cause. It obviously altered or removed what ever was needed for it to work properly. Tried looking for a changelog but still didnt know exactly what to look for there. Instead of looking for just the quick fix, i would like to know what to do in this situation, and how and where to find what i need to fix this. if I later decide to try a Debian distro, i am sure i will need to acquire this knowledge and capability. A step by step video would be helpful unless you can point me in the right direction of where "how to find this info" is already documented.

[@n8lbv]

Do you have a video where you cover drive UUIDs Partition UUIDS and EFI? I pulled an all-nighter getting more familiar with it. I have avoided "newer" Linux and UEFI for a long time. I have a Debian UEFI VM (Hyper-V) where I had to figure out how to actually resize the disk and the local VHDX file as I had it set to be able to expand to larger than the local SSD array it runs on had the space for. I know for a fact my EFI/grub stuff is still borked. On the initial boot menu when looking at the boot config it still refers to old drive UUIDS. The whole thing is on a new virtual drive. I of course had to edit fstab to get it all happy and working. I'm a bit confused WHY the grub/EFI stuff needs the UUIDS at all as it is working, or at least booting properly even though when you stop the boot and hit "e" to edit the boot options I can plainly see that the boot config does not have the proper drive and/or partition UUIDs configured. Yet it seems to work fine. I'm in the process of figuring this out. By guess is that even though it "works" there is probably a boot delay caused by this while it tries to locate the configured UUID resources. And then it goes ahead and figures how to boot what is there. This is certainly a UEFI install as I (not really knowing what I am doing yet fully) manually created the FAT32 EFI partition and rebuilt it from commands. It did not auto-fix my grub config where the old UUIDs are still referenced. This is probably just a matter of editing something for grub and rebuilding the boot config, but I'm new at this and still figuring it out. Most of the videos and forum posts on the Internet are rabit holes as expected. I can tell how relatively simple this is yet most out there do not have a clue how it works. That included me for a long time. I have a clue but not fully there yet. Steve the tech guy in Michigan. :)

Great video, you made fixing Linux look easier than fixing a botched Windows Update! XD I have also found it useful to have Gparted on hand on a USB key/CD as well. It's lightweight, and has a basic GUI that's functional enough to open multiple terminal windows up for those cases where you need to look at things side by side on the system like live files vs backup files and Gparted itself is great for resizing/moving partitions around. Knoppix can also be pretty useful, albeit overkill and a bit top heavy, but you can transfer files off the broken system with it in a GUI if that's what you prefer.

[@frenk051]

11:37 "dd" stands for "data duplicator". At 11:58 you can see why its alternative (and way more popular) name is "disk destroyer".

[@edwardbartolo6382]

"dd" also stands for disk destroyer! Why would anyone want to use a very low level tool that can easily damage the data on an entire disk? There are ready made utilities for boot failure: I strongly suggest users to use those first. Boot failure can be mitigated by using a dedicated partition for a tiny OS hosting the bootloader. This way, no installation can ever modify the bootloader and booting is thus guaranteed for all installed operating systems. To achieve this instead of kernel file names I use the "/vmlinuz" symlink in grub.cfg. Note and Warning: Using a separate operating system for the bootloader requires manual editing of grub.cfg which can result in boot failure if not done properly. Manual editing avoids having to use user scripts to custom configure grub but it has its downside especially for people not familiar with programming languages.

[@frenk051]

I did mention the "disk destroyer". And wouldn't you agree that using dd to create a bootable recovery medium is still way simpler and less error-prone (with necessary precautions, of course) than the procedure you suggested?

[@wynnhorton1208]

CentOS' page recommends dd. i think I used it to put Anaconda on my flash drive and no amount of formatting in any tool will remove Anaconda now.

What about the Ubuntu login loop? I’m on Mint and I’ve tried everything to get this resolved and nothing works. The problem seems to be a lack of space in /var/cache/apt/archive/. But it just doesn’t make sense, why should this file have so much less space than the rest of my computer? And how do I actually clear up some space? The files I see don’t seem that big and I don’t want to remove them if I don’t know what they are.

[@yvrelna]

Another trick that often saved my ass, especially on systems that does not have a CD/DVD drive or when you don't have a USB pendrive with you, is to boot directly into an ISO image file. Suppose that you have an bootable Live ISO image of the distro of your choice in your /home/user/Downloads/ folder or suppose that you have the foresight to put a Live ISO on your /boot/ folder. You can use Grub Shell to loopback mount the ISO image and boot directly into that disk image; this has the exact same effect as booting from USB drive without needing any extra hardware (or access to the USB port, if that matters). From the Live system, you can edit files on the installed system or chroot into the installed system, and if you used Live ISOs that boots into a graphical environment for installer, you would be able to do your fixing from a GUI environment (which has the benefit of having a working networking and a web browser).
