If the message you are seeing is this: overlayfs: missing 'lowerdir' Then your disk is full and you'll need to boot in recovery mode (or with a Live USB / DVD) and delete some unnecessary files. This could be the result of excessive logs in /var/log or just about anything else that might fill a storage device to capacity. Once the device has enough free ...

(Duplicate of my other answer: https://askubuntu.com/a/1364688/720219) Purging the package is not enough: ucf (update configuration files) protects the files. One way to avoid this is to force ucf default action. I didn't had much luck with confmiss in dpkg options, so I've read the ucf documentation. override the default ucf action, to create configuration ...

Boot Menu every Boot When booting in BIOS mode Xubuntu uses the Syslinux menu from the txt.cfg file. Pressing the shift key will make the screen in your image appear, (along with the Language menu). When booting in UEFI mode the GRUB menu from grub.cfg normally appears. Boot partitions can be added, (as with mkusb), to enable GRUB booting in BIOS mode also. ...

As the other answers already explained, you can conceivably use either GPT or MBR and it will work just fine. However, there's one major advantage of GPT, and that's reliability/resilience. The MBR partition table is stored in a single disk sector right at the beginning of the device. Should anything bad happen to that sector (say, disk block going ...

If your main SSD is in GPT, then I would advise on making the 2nd SSD GTP too. And vise versa. P.S. instead of dual boot, why not try virtual machine. It's more convenient.

Bad installation media(For the usb drive) gave these rather unhelpful messages. This was compounded by the fact that IRS, Intel Rapid storage, was activated on the disk. Which apparently makes it inaccessible to the Ubuntu installer (don't quote me on that). This is my first contact with IRS. I strongly suspect that IRS made the install(iso extracted) ...

Both Windows and Ubuntu support both MBR and GPT alike with no issues. What can be different: The size limitation - MBR is limited to 2TB disks, GPT limits are much higher and irrelevant for modern disks. Booting - older motherboards may have issues booting off a GPT disk, modern ones sometimes get picky with MBR. Other elements of booting (e.g. efi vs csm)...

Microsoft recommends using UEFI for Windows which requires GPT. It is also a more modern system. https://docs.microsoft.com/en-us/windows-hardware/manufacture/desktop/windows-and-gpt-faq Ubuntu's bootloader GRUB will only load Windows if Ubuntu and Windows are both either BIOS or both UEFI. It is best therefor to initialize both Windows and Ubuntu as GPT. ...

Either MBR or GPT would work. MBR is limited to 4 partitions... but due to a bug in Microsoft's Windows updaters, major Windows updates tend to wipe out MBR Linux partitions and GRUB (on single-drive installations). MBR tends to be used on older BIOS computers. GPT doesn't have the partition limitation of MBR, and it looks like your Windows disk is probably ...


1

I don't think it matters in your case; both MBR and GPT are supported by both Windows and Ubuntu, and the 2TB limitation for disk size on MBR isn't relevant to the disk size you have (and I presume you're not planning on having more than 4 primary partitions which MBR is limited to). I'd personally probably go with GPT as it's more modern, but there's not ...

It's debatable which is better in different environments. But setting the second SSD to the same technology as the first will lead to less potential confusion in the future. So if your first SSD is formatted as GPT set the second one the same. Ubuntu supports both MBR and GPT without any problems (that I know of)

I just got it working. I had an intuition that if I can somehow wipe my HDD clean ( removing the data including the file system ) I can get it working. Googling ways to "nuke" my hard drive without Booting lead me to DBAN. You can make a bootable disk using this and then wipe your hard disk using the quick clean method. There are tons of tutorials ...

Since several other problems will occur concerning the NVIDIA driver after you solve this ACPI error (took me two days to find the way out), I will provide my complete solution.

The 3GB of memory will certainly be an issue for Gnome-based desktops since 2018.

You are right about /boot/efi. The bootloader for UEFI mode resides there, but if you boot in BIOS mode (alias CSM alias legacy mode), you do not need it. I think that the installer creates it anyway. This is a new 'feature' of 20.04.x LTS, we did not see it in previous versions (at least not previous LTS versions) installed in BIOS mode. In order to be sure ...

You have a few options. You can physically disconnect the disk with Windows before installing Ubuntu so that you can use this "Erase disk and install Ubuntu" option, then reconnect the disk after installation. You will need to update GRUB so that Windows is an option in the GRUB bootloader. But the better option would be to format the disk with ...

You can just re-install Ubuntu but your question is rather unclear as it's missing details. Re-installation doesn't require the old passwords, as your new passwords will replace the old (system directories get erased so old passwords will be deleted), HOWEVER if you used encryption all data will be lost. You can install without loosing any data; just ...

FYI, ftp is not supported by cloud-init. This can be confusing because the documentation used to claim that is was, but that should be fixed now. Since you claim that you also tried http without success, here are a few thoughts (for these items I simply replaced ftp in your URL with http for demonstration purposes) wrap the ds argument in quotes. ...

Somehow --location cannot find kernel and initrd for Ubuntu image.

Speaking as a former low-level NHS IT guy - do not do this. I completely understand why you want to. Everything about official NHS IT is absolutely terrible, which is why I left.

I think I have an answer. See this link. According to that link, your computer is probably booting in UEFI mode, and if you switch in the BIOS to CSM (alias BIOS mode alias legacy mode), the graphics will probably work for you. At least it did 8 years ago (with Ubuntu). It turns out the option to change between UEFI and CSM was buried under a sub-menu that ...

Note that I do not recommend this for an entire premises: that would need dedicated IT support.

The next point to make – for anyone contemplating this - is that I have done this and it works much better than I anticipated, with ...

Normaly you have to add a efi-partition on your SSD, 100MByte would be okay. I use Linux for more than 12 years now and separate /boot and /home was not useful. You should add on your SSD: efi-partition (100MByte as fat32 - Mounted as /boot/efi) / Partition ~480GByte (with home and boot) On your HDD you can put all your personal stuff. I have created a ...

You people are all wrong. Its some compatibility issue between the bios and the os. I had ubuntu working 100% fine, but when i switched motherboards, it doesn't show up. I know the drive works, as the windows partition i have dual booted with ubuntu works fine. There has to be some setting in the uefi utility that prevents grub from working.

You should not touch the cache. It is managed by the operating system. Linux strives to maximize the use of fast RAM. Anything not needed for your applications will be used as temporary cache. Items written to disk will be kept in memory, so later on, if the item is needed again, it can be retrieved from fast memory rather than from slower disk, and so the ...

This is a very similar question to Will all my files be deleted if I choose 'Erase disk and Install Ubuntu' when installing in a VMWare virtual machine? although that one seems to be from the Ubuntu 18 era.

i386 ISOs are available, however the last Ubuntu Desktop ISO for i386 was for Ubuntu 17.04. eg. https://cdimage.ubuntu.com/netboot/bionic/ where you'll note a i386 - For 32-bit Intel/AMD (x86) There were just fewer options, namely no Ubuntu 18.04 LTS Desktop ISO. Flavors too offered 18.04 i386 ISOs; however flavors only come with 3 years of support, thus ...

Although Ubuntu does not have a 32 bit ISO for version 18.04, you can use 32 bit ISOs for Ubuntu flavors like Ubuntu MATE, Xubuntu or Lubuntu. If you need to use the GNOME desktop (Ubuntu's default desktop interface), you can later on install it with sudo apt install ubuntu-desktop But if you have an old PC (which is likely, due to the 32 bit processor), I ...

That looks strange, your "main" disk is not even mounted. What you see is only your USB stick. You need to install Ubuntu "besides" Windows. Since Windows is probably installed in UEFI, Ubuntu needs to be installed as UEFI as well. When installing you need to make sure that the windows partition is large enough for another OS. Many years ...

By trial and error, I figured out what was causing the problem. I mentioned an 18 TB encrypted drive in the original post and it turned out the OS was unable to use it for longer than a few minutes. The drive itself is fine (I'm using it right now), but the OS simply can't use it with encryption. After a few minutes it would lock up ALL drives and render the ...
