Ubuntu Booting Issues – (Unknown File System errors) Version 18.04.1 LTS

Yesterday when a formatted an external USB drive i thought i made a mistake initially in selecting the wrong drive. Everything as fine though, nothing went wrong initially.

After all that had happened my computer continued to work fine. Went to bed;woke up today and started working and everything was fine (i did not power off last night it was on sleep mode). However l was trying to install this dev tool and to make sure everything was working l restarted it and it wont boot properly just an ‘unknown file system’ error when l boot.

l used a live USB Ubuntu (Try Ubuntu) to recover and followed some instructions to use boot repair from: https://www.howtogeek.com/114884/how-to-repair-grub2-when-ubuntu-wont-boot/

l did that and tried to restart again and still am ending up with the same file system error. Keep in mind l already checked all the file systems using the commands on Grub to check if it was loading from the right partition but all of them turned up with nothing any ideas ?

Graphics driver causing boot issues | Ubuntu 18.04.1

I added the graphics-drivers PPA and installed the 415 driver, but it seemed that in doing so my 940MX was no longer being utilised. So, I attempted to revert to the 390. I made the mistake of removing the PPA before switching away, though. When I tried to switch back to the 390 driver, Ubuntu spat out an error – I can’t remember the exact message, though I believe it mentioned something not being found in cache.

After restarting my system, the boot process got stuck on a screen flooded with countless “Starting NVIDIA persistence daemon” and “Stopping NVIDIA persistence daemon” messages. To get the system to boot, I had to enter recovery mode and use prime-select intel. If I use the Nouveau driver the system can boot, but my laptop doesn’t seem to use my GPU.

Running nvidia-smi produces the following:

NVIDIA-SMI has failed because it couldn’t communicate with the NVIDIA driver. Make sure that the latest NVIDIA driver is installed and running.

I followed the advice here, but it unfortunately didn’t help. I’ve attempted to remove any remnants that the 415 driver may have left behind. Initially I looked this thread, but regarding the page linked by it the directory /usr/local/cuda-X.Y does not exist (as in, theres no cuda-related directory), and the link /usr/bin/nvidia-uninstall points to nvidia-installer, but that doesn’t exist. So, I removed the packages as recommended in accordance with this answer. I then set the driver to NVIDIA’s 390 in the software settings, so it re-installed everything. Still, restarting with the NVIDIA GPU selected stops me from being able to boot.

The result of dpkg -l | grep nvidia at the time of writing is the following:

How do you get mouse wheel to scroll the page and not the cursor? [Ubuntu 18.04.1 LTS]

I apologize in advance if this has already been asked. I have searched for this solution for a couple hours now and could not find what I’m looking for.

I am primarily a Windows user. In Windows, if I scroll up or down with the mouse wheel in a text editor, the entire window moves. In Ubuntu, I notice that the mouse wheel causes the CURSOR to move, and the window only moves once the cursor reaches the edge of the window.

Is there a way to change this so that scrolling the mouse wheel causes the page to move while leaving the cursor in place?

Preseeding Dual boot dual hard drives Ubuntu 18.04.1 LTS

First post here. Just wondering if anyone can help. I’m not Linux expert or anything so this may just be my brain frazzling!

Ok, so I’m using the same hardware and same method I have been using with 16.04.x which all worked fine. I am using a fairly new pc with two nvme hard drives in (one 500gb and one 250gb). In my preseed file under partitioning I specify the 250gb disk (d-i partman-auto/disk string /dev/nvme1n1) for Ubuntu as Windows goes on nvme0n1 (the 500gb disk). My auto deployment/installation of Ubuntu works fine for a few times but then suddenly i’ll find that for some reason its installed itself onto the 500gb disk instead of the 250gb?! If i then look in gparted or do lsblk the disk labels have swapped over so now the 250gb disk appears as nvme0n1 instead of nvme1n1 and the 500gb appears as nvme1n1 instead of nvme0n1. If I reboot then usually the labels have switched back to how they should be but obviously Ubuntu has now written over the windows 500gb disk. When i deploy Windows 10 via sccm it will consistently deploy to the 500gb disk (disk 0) Any suggestions or workarounds would be greatly appreciated. Currently i’ve sort of given up on this and am waiting for 18.04.2 to see if that fixes anything. Thanks Rob

Ubuntu 18.04.1 live usb boot error(s) – Unable to find a medium containing a live file system

I have a HP 15-ba004nq laptop (CPU AMD A8-7410, RAM 4GB DDR3) on which I have a broken Windows 10 installed and I’m trying to boot it using a Ubuntu 18.04.1 on a USB (8GB).

I only need to boot it so I can save my pictures from the desktop. Earlier today I managed to boot it and I found the Desktop folder and all my pictures. But then I’ve shut it down and went out to buy an external drive but when I came back I couldn’t manage to boot it up again.

I’m getting the Ubuntu logo and those blinking dots

enter image description here

but then – after ~1 minute of ‘blinking dots’ – there are a few errors:

enter image description here

So i started to search for those problems online and I found a few similar questions so I’ve tried out those answers:

  1. Try using another USB port – I’ve tried them all
  2. Make sure that the Secure boot is disabled – Yes, it is
  3. Try making the usb again using partition scheme GPT instead of MBR – tho it seems a bit wrong to me i’ve tried this one to but since it didn’t work I made it back to MBR

P.S: I’ve used Rufus 3.4.1430 to make my USB fallowing this tutorial.

Slow WiFi connection on Ubuntu 18.04.1

I am new to Ubuntu and after I installed Ubuntu on my PC, I am experiencing a terribly slow WiFi connection (but faster on Windows). I tried to disable the 802.11n and the Intel driver card but it gives me the following error (running sudo modprobe -r iwlwifi):

rmmod: ERROR: missing module name. modprobe: FATAL: Error running remove command for iwlwifi 

I also tried following this answer but lspci -nn | grep 0280 returns nothing on my Terminal.

When running lspci -knn | grep -i net it returns:

00:19.0 Ethernet controller [0200]: Intel Corporation 82567LM-3  Gigabit Network Connection [8086:10de] (rev 02) Subsystem: Dell 82567LM-3 Gigabit Network Connection [1028:027f] 

Any help would be appreciated. Thank you so much!

Failed installation 18.04.1

I’ve been trying to install Ubuntu 18.04.1 64-bit on an apparently healthy Seagate Pipeline HD (Model ST3320310CS) SATA HDD. Each time a dialog box tells me there is an “apt configuration problem” “An attempt to configure apt to install additional package from the CD failed“. I am then told that the installation has failed. In the case of this Ubuntu installation I’ve been using a USB key, burnt via Unetbootin. Via this USB key, I can see that many Ubuntu files have been copied on to the HDD, but the installation refuses to complete. I also tried another USB live key, but the result was identical. For both USB keys, the sha256sum checks I did were successful.

I previously tried installing Ubuntu Mate 18.04.1 on the same HDD on 2 different 64-bit computers (with both a USB key and DVD) and the message I received was very similar to the one above.

I ran the hard drive DST short test from the BIOS and it passed. According to the screenshot for this HDD (taken via the Ubuntu live USB key) [NB AskUbuntu has refused to accept this png image in my post] , the assessment for the HDD is “ok”.

I’m totally perplexed why the installation won’t complete; I’ve installed Ubuntu, Lubuntu etc with no problems on many occasions in the past on used HDDs. However, I recently bought this problem HDD from a local dealer and although it didn’t come with any packaging, it looks unused. So I’m wondering if I have to format it in some way before trying to install? If so, I’m wondering how to proceed now with all the Ubuntu files that are already copied on to it?

Although I’ve gradually learned how to do some very rudimentary technical things on Ubuntu (like doing the sha256sum check and doing a few commands on Terminal), my know-how is still extremely limited. So bearing this in mind and that this HDD will only have Ubuntu installed on it (and NOT Windows), I wonder if you suggest that I try to follow the instructions on this Help page to install a new hard disk here:

https://help.ubuntu.com/community/InstallingANewHardDrive

The above instructions are looking extremely daunting to me at the moment! So do you think I might find it easier to look at Seagate’s “DiscWizard” software (available online according to the sticker on the HDD) ?

Many thanks in advance for any replies.

Ubuntu 18.04.1 LTS Server kernel panic on Linux 4.15.x kernel

I was using Ubuntu 14.04 LTS Server then upgraded to Ubuntu 16.04 LTS and then to latest LTS version of Ubuntu 18.04.1 LTS Server.

Updates changed the running kernel version to. Now my computer has two Linux kernels as 4.15.0-43 generic and 4.4.0-141-generic. The first option is 4.15.x and stucks on kernel panic if it is selected.

Here is screenshots of error:

Kernel panic on Linux 4.15.0-13 generic kernel

And here is my kernels installed: enter image description here

Kernel 4.4.0-141 succesfully boots but I’d like to use new version of Linux kernel.

Also there is another issue with Ubuntu 18.10, there was the same error but community updated Linux kernel version to 4.18.x then problems were gone.
