End trace error after upgrade to 18.04

Hi

I have a server version and just upgrade to 18.04 LTS by do-release-upgrade. But I got error "end trace..." when I reboot the computer. Now I boot it from 16.04. It keeps telling me to upgrade to new version when I login. But if I do do-release-upgrade again, it tells me there is no new version. What can I do?

Thank you very much!

Hi, I’m having trouble getting Ubuntu install on my system. I am using an ati Radeon 5870 with 6 displayports. I have it connected via one of the displayports. When I tried to install via the usb, I get a black screen when I select either try Ubuntu or install. The monitor says out of sync, incorrect timing. My monitor is a dell u2718q. I can get it to install with options “ro nomodeset vga=791”. Once installed, I get the same black screen, monitor out of sync, incorrect timing. Also, I can’t see the grub menu, try pressing shift, etc. the display says no signal. Any help?

If I install 18.04 will I lose my 16.04 settings.
Do not want to upgrade directly from 16.04 as I encountered internet connections when I tried it before.

[ubuntu] Upgraded from 16.04 to 18.04 & now boot fails

My upgrade seemed to go fine until the reboot portion. Then I encountered an error that prevented me from getting to the splash screen. A live version of 16.04 worked, but 18.04 live would not. I discovered that the issue was the result of an outdated version of my HP bios. I have updated my bios and the boot now gets to the splash screen and hangs. Booting into recovery works now and live booting 18.04 works. When I boot verbose I see that the error now is
Code:
modulenotfounderror no module named 'distupgrade'
. I have my /home and /usr setup on individual partitions and am trying to back them up in a live version of 18.04, but I can not get it to recognize my usb drive.

I don't particularly want to re-install and certainly not if I can't back up my /home and /usr before the attempt. Any help is greatly appreciated.

[ubuntu] Ubuntu 16.04 - 18.04 upgrade fails -- critical pkg could not be installed

I have been avoiding upgrading from 14.04 because of issues with 16.04 (flashing screen).

I finally decided to bite the bullet. The 16.04 upgrade seemed to work with no issues. I tried compiling and running a program in my Eclipse CDT, and it successfully worked. My Firefox seemed to work fine although Facebook locked up on me once. I had to do a hard reset. This is a generic Dell i3 laptop with 4GB.

Thinking I was okay, I did sudo apt-get update / upgrade one more time, and sure enough, it wanted even more updates and a reboot.

Started upgrade-manager. It did say that the 18.04 upgrade is 'recommended'. I proceeded.

The first failure was fontconfig, then it failed in installing 'systemd'. Realizing that not having that would probably hose the system, I tried to do damage control.

Can't get ALT-F2 to work, it changes sound volume. Can't open a terminal window, so I couldn't run ubuntu-bug. My SciTE text editor won't save and crashes regularly. Gedit won't launch at all.

Final error message is:

Could not install 'systemd'

The upgrade will continue but the 'systemd' package may not be in a working state. Please consider submitting a bug report about it. :(

triggers looping, abandoned
some Python utilities, until I closed the bu
The fontconfig message was identical except for programname.

The upgrade halted unpacking some Python utilities until I closed the bug warning window.

I do have another 14.04 system but I'll have to take down my Doze box for its KB, mouse and monitor.

kernel not upgrading

Hi folks,

I just upgraded my server to 18.04 and it displayed some information about the L1TF vulnerability, so I checked it out and I read that new a new kernel would fix that.
But I realised that I am still on 3.13 kernel Linux aragorn 3.13.0-63-generic.
apt doesn't show any upgrades, but I thought that 18.04 would bring the 4 series kernel. I don't really mind staying on 3.13 because everything is working fine, I was just wondering what might cause this.

Thanks!

18.04 cloned to SSD still mounts HDD as file system root

Hi,

I'm trying to clone an existing Ubuntu 18.04 system that's installed on a 1TB hard drive (sda1) to run from an 250MB SSD (sdb1). Only about 30GB is in use on the sda1 partition. The steps I followed:

1. Booted from Live USB, and used gparted to reduce sda1 to 100GB
2. Used clonezilla to clone the reduced sda1 partition to the SSD.
3. Assigned a new UUID to the SSD partition (because it was identical to the HDD UUID after the clone)
4. Modified /etc/fstab on the SSD to use the new UUID of the SSD.
5. Ran update-grub

On reboot, the grub menu appears to include an option to boot Ubuntu from the SSD. If I choose that, the system seems to come up normally, but then lsblk indicates that the file system root is still mounted on the HDD (sda1), instead of sdb1. (which AFAIK means that the system is still running from the hard disk.)

What have I missed?

Thanks in advance.

Upgraded from 16.04.5 to 18.04.1 both LTS. Now I can not get connection with my WiFi.
I believe this is keeping me from adding new applications, and my WiFi printer.

OK, it worked just fine in 16.04 but now it seems the WiFi connection is broken and not connecting.

One my AcerONE 725 Netbook, I just upgraded from 16.04.5 to 18.04.1. I seem to not have permission to install apps from the Software Center, so why not?

So far this clean install of 18.04.1 has been a bear, with lots of problems. Including the WiFi being on and off it drops out often. This does not happen with my System76 laptop. I did not have it before upgrade either.

I have had trouble with UbuntuONE Singlesign In with the Acer. I have not gotten all the settings made yet, so I do not know what other problems I will encounter.

I've been trying to install Lubuntu 18.04 from a USB alongside Windows 10. I followed a guide to shrink the partition from the Windows disk manager. The guide said to name it E:/. When i run the Lubuntu setup, it skips the regular Installation Type screen and goes directly to the Something Else option screen. In the table, all it shows is /dev/sda. And under boot loader, the only option is /dev/sda Generic Flash Drive. Did I make a mistake shrinking? I'm not sure where i went wrong. Thanks in advance for your help!

[server] Black screen after GRUB with alternate 18.04 Ubuntu Server install image

August 23, 2018, 11:31 pm

I have just gotten a new laptop (Lenovo X1 Yoga 3rd Gen), so time to install Ubuntu on it! I like to build up from a minimal install so I typically install Ubuntu Server and then build up from there. I like to leave the Windows install that comes on the laptop on there and dual boot. As the new "standard" server installer only seems to allow you to wipe a drive to a clean slate when installing and I want to keep the existing Windows install, the alternate installer is my only option.

My problem comes about when I try to actually boot the installer. I can easily get to the GRUB prompt, and after selecting the "Install" option the screen goes black (though is still obviously on) and nothing is displayed. I have tried removing the "quiet" kernel options and setting "--verbose text" to see if I get any output that I can work with to no avail. I have also tried the classic "nomodeset" with no improvement. To give insult to injury, the "standard" server installer boots fine and lets me get far enough to show me that it wants to nuke my drive. The desktop live "CD" also boots without issue and was actually used to begin with to resize the existing Windows partition to make way for Ubuntu.

I have tried a handful of USB drives, burning the ISO to them using Rufus 3.1.1320. I have Secure Boot disabled and the boot mode set to UEFI only. I have attempted to boot from server install "disks" for 17.10 and 16.04 with the same issue.

So, any advice on how to debug this further or other avenues I could look at for installing Ubuntu without wiping my drive?

Thank you in advance.

Ubuntu has told me that software updates are no longer provided for 17.04, and that to stay secure I should upgrade, but when I hit the upgrade button, after the upgrade tool downloads, an error is output:

Code:
Cannot upgrade from 'zesty' to 'bionic' with this tool
I assume the problem is that this tool does not account for the edge case of those missing an upgrade.

Must I first upgrade to 16.10, and if so can you please tell me how to do this?
