[ubuntu] Messed up dpkg locks and stuck in forced package reconfiguration loop. Help!

While trying to get out of a dpkg lock issue,
https://askubuntu.com/questions/1543...nother-process

I manually removed these locks (unwisely)
sudo rm /var/lib/apt/lists/lock
sudo rm /var/lib/dpkg/lock
sudo rm /var/cache/apt/archives/lock
sudo fuser -cuk /var/lib/dpkg/lock; sudo rm -f /var/lib/dpkg/lock
sudo fuser -cuk /var/cache/apt/archives/lock; sudo rm -f /var/cache/apt/archives/lock

Now forced package reconfiguration hangs with the following :
sudo dpkg --configure -a
Configuring postgresql-common ├─────────────────────┐
│ │
│ Obsolete major version 9.5
│
│ The PostgreSQL version 9.5 is obsolete, but the server or client

│ The old server and client packages are no longer supported. After the

It hangs here, and the only way out seems to be reboot.
I could pg_upgrade to pg12
But trying to remove these pg9.5 packages, again throws this reconfiguration error:

sudo apt remove postgresql-9.5 postgresql-client-9.5
E: dpkg was interrupted, you must manually run 'sudo dpkg --configure -a' to correct the problem.
I am stuck in a loop. Help!

I zsync'ed todays ISO 05032020. Apparently there's a new shell ( 3.36.1-5ubuntu2). Read below why I can't install tweaks:

Code:
sudo aptitude install gnome-tweaks
The following NEW packages will be installed:
  gir1.2-handy-0.0{a} gnome-shell-extension-prefs{ab} gnome-tweaks
0 packages upgraded, 3 newly installed, 0 to remove and 0 not upgraded.
Need to get 74.1 kB of archives. After unpacking 541 kB will be used.
The following packages have unmet dependencies:
 gnome-shell-extension-prefs : Depends: gnome-shell (= 3.36.1-5ubuntu1) but 3.36.1-5ubuntu2 is installed
                              Depends: gnome-shell-common (= 3.36.1-5ubuntu1) but 3.36.1-5ubuntu2 is installed
The following actions will resolve these dependencies:

    Keep the following packages at their current version:
1)    gnome-shell-extension-prefs [Not Installed]       
2)    gnome-tweaks [Not Installed]
Is the released Focal really have gnome-shell 3.36.1-5ubuntu1 ?

[ubuntu] Trying to boot Ubuntu for the first time but I'm getting stuck at the loading screen

I am trying to boot Ubuntu (20.04 LTS) for the first time on a HP ENVY laptop to replace Windows 10. I followed Ubuntu’s instructions to create a bootable USB using Rufus and selecting the USB from the boot manager. However, whenever I do so, it scans the file system successfully and thereafter I get stuck on the Ubuntu loading screen (image atached) and nothing happens except the loading circle spins. I have tried it multiple times and even left it for over 12 hours, but to no avail.

Thank for any help in advance.

[ubuntu] Ubutnu20.04 stucks in boot logo screen

Ubuntu20.04 stops on the DELL LOGO Boot screen as shown in the following image.
20200504_205044.jpg

The PC I am using is a Dell XPS 15 Laptop. Also, I'm running dual boot with Windows.
In previous versions (16.04 and 18.04), such a phenomenon did not occur.

Once I enter the recovery mode, I can log in with resume. However, when I reboot it, it stops at the Boot screen in the same way.

I reinstalled Ubuntu20.04, and when I started it with resume, I ran
Code:
sudo apt update && sudo apt upgrade && sudo apt full-upgrade
, but it didn't improve. This problem has been occurring since the Beta version.

Please let me know if anyone knows how to solve this problem.

Can I instal Ubuntu on a non-bootable drive ?

Newbie here. I was surprised I couldn't find this in a search, since I would think it would be a common situation.I have an older system that is plenty fast enough, but it only has sata2 and does not support pci-e booting. So my new SSD is bottle necked by the sata2. If I install grub on a drive the bios sees as bootable, can Ubuntu and W10 be on the SSD connected to a pci-e card the bios can't boot from?

Ubuntu 20.04 - Nvidia fan / overclock control issue (gpu mining rig)

May 4, 2020, 12:51 pm

Afternoon. I have installed Ubuntu 20.04 on this rig multiple times today due to screwing various parts up when trying to enable fan and overclock controls on my gpu's. I now think I've yet again screwed something up with xorg so in the process of a clean fresh reinstall and looking for some guidance on my next steps. What I have is a rig of 4 gpu's and it's running off the onboard video from the intel cpu. After the clean install it is great to see it installs the nvidia drivers correctly and when I do a nvidia-smi all looks well. In the past my next step was to do a sudo nvidia-xconfig -a -cool-bits -28 and this is where my problem arises. After doing this step I can no longer boot. It'll stop at a blank screen with Ubuntu written at the bottom and nothing else. Control + Alt + F2 does nothing. And on this first install I forgot to setup SSH so well, had to reload. 2nd time around I installed both XRDP (so I can remote locally with windows remote desktop) and I also added SSH as a backup. I read that I needed to run nvidia-settings and go to x config and save the configuration. Well problem arose with this. All that shows up is at first 3 options to choose. Power Mode. Nvidia On Demand or Intel power saver (can't recall exactly the wording). I choose Nvidia On Demand and rebooted. Then going into nvidia-settings I now see what I am familiar with, however still no nvidia x configuration screen. All I have is my 4 gpus with their thermal, power and a profile option to save and then the screen again to choose from the 3 original options (power, nvidia on demand, intel).

So this time I ran sudo nvidia-xconfig -a -cool-bits -28 again so it created a config file for me. Made a backup of the file. And then sudo nano to edit the original file and tried to make changes to mimic what a default file would look like (had I just done sudo nvidia-xconfig with no options, the output that gives). And after reboot well, same issue. Blank screen with just Ubuntu at the bottom. And Control Alt F2 does nothing. So tried SSH and that worked. Great. So did a rm over the file rebooted, and tried again. I read in another forum that I could create a folder within X11 named xorg.conf.d and then create a conf file like 28-coolbits-conf and then the following:
Section "Device" Identifier "Device0" Option "Coolbits" "28" EndSection

Tried this, back to blank screen. Edited this file thru SSH to -28 thinking maybe I needed that hyphen and well still not working.

So my question is how can I enable fan control and overclocking abilities on nvidia gpu's now?

Thanks

[ubuntu] New Ubuntu 20.04 installation stuck after login

Hello everyone!

I tried searching but couldn't find anything to solve this issue.

I tried several times to install Ubuntu 20.04 using the "Ubuntu" option, but it always was getting stuck in the filesystem check at 0% in the beginning of the installation. Trying to hit Ctrl+c did nothing.

I could finally install it using the option "Ubuntu (safe graphics)" option. BUT, after installation, it took a long time to start, around 5 - 10 minutes - It was installed in a SSD drive. The login screen finally was presented, but after typing my user and password, the UI is stuck. It's only a purple screen with the mouse pointer.

IMG_20200504_191718.jpg

Tried several times and the result is always the same: long time to start and the mouse in a purple screen.
Tried reinstalling it and the same issue happens.

Anyone knows what may be happening?

My laptop is a Dell Inpiron 15 gaming with core I7, 16 GB RAM and nVidia GeForce GTX 1050 Ti.

I had the same issue with Ubuntu 19.04 and this was the reason to give up using Ubuntu in the past. I just couldn't find a solution for that.

Thank you very much in advance!

[lubuntu] No grub after fresh install and cannot restore grub

Hi,

After installing Lubuntu 20.04 over 18.04 there is no grub menu, and attempts to restore grub fail, both via the Boot Repair tool and reinstalling grub via the command line. I am copying my output from the latter here. My disk partition is odd: 2 Windows recovery environments and 2 swap partitions.

How can I sort this out?

Many thanks.

upgrade 20.04 does not show in update

Hello, I have Ubuntu 19.10 installed in dual boot on an Asus Zenbook UX434F, Update 20.04 does not show on the software updater. It says my system is up-to-date. I have also check with Synaptic "mark all upgrade", to be sure. It seems that my system is indeed up-to-date, and I would expect the software updater to propose the version upgrade.
Why doesn't it show ?

I wonder if there is a link wiht the installation. When I bought the PC a few months ago, I had to upgrade the BIOS to the latest version to allow the installation on a SATA SSD drive. Without updateing the BIOS, I could not select AHCI for SATA operations, which was needed. Since the, I had a perfectly working system.

Any hint ? Should I just wait a little bit more ?

Thanks

AMD A10 from 2013

Hi all,
Sorry i started asking about my installation problems in another thread but can't find it anymore.

I had an HD crash and needed to install windows XP again and that was also the moment to try Ubuntu.

I've now done with my backup and try to find a solution for my operating system problem.

That's why I downloaded Ubuntu and put it now at a usb stick. That's a sure way to crash my PC!
Booting with the DVD works but causes my monitor to switch off ... I think two times ...

I'll report here later at the moment I try a demo from Windows 7 and later windows 10. I have also vista but don't knew if I can still activate it.

At the moment I am disappointed that booting from a stick doesn't work. Maybe that can be fixed?

Big mess to my boot sequence and grub installation.

I had the following:
Sda Not EFI - Grub2.04 - Win 10 - Ubuntu 20.04 - Swap

Then I installed mint cinnamon on sdc, which was formatted at install.
Sdc is now EFI and can boot cinnamon if I boot to sdc efi. But if I boot sda I have windows and ubuntu only (no mint)on sda.

So I went further and did some damage.
Destroyed ubuntu and swap from sda (it was dumb I know now)
Installed ubuntu alongside mint on sdc.

Now from sda grub cannot work (logic as I have deleted ubuntu parition). I would like at least to be able to boot windows from sda (imagine sdc failure), but evrything from sda would be great.
From sdc I boot to linux mint boot which looks different than bare grub. I can access either mint or ubuntu but not windows.
I tried boot-repair through mint ubuntu, installed and live. I have also tried boot-repair iso and supergrub2 iso. It either fail because of conflict with gpt or it pass but I have no difference at startup.

http://paste.ubuntu.com/p/8K8mkyRxrS/

I can format sdc or unplug if necessary. I can do any iso on usb. I wish to maintain my windows partition and be able to boot it. My usb stick always appear as EFI in bios, I don't know if it is part of my problem. I have a2gb and a 16gb stick on hand.

But I don't know how to tackle my issues and in what sequence.
Any advice?

Hi Guys,

Recently i installed Ubuntu 20.04 LTS on my desktop.

Originally it ran only windows, after installing then the computer boots to windows only.
So after doing some research i tried using BCDEdit but cannot because my system is UEFI.

I tried turning off UEFI in BIOS and tried re-installing Ubuntu again but it does not work.

Can someone assist me so i can install Ubuntu alongside windows please.

thanks you

[ubuntu] Advise for no video on 20.04 start-up - have reviewed sticky extensively

Hoping that someone can help with being unable to see on start-up any grub, graphics, other than a frozen cursor, after a fresh install of 20.04LTS. My system is a 2010 iMac with AMD graphics chip no longer supported, so requiring nomodeset. In addition, since OSX will not work due to the AMD graphics having gone bad, it is single boot and had been running 18.04.4LTS perfectly.

I tried 20.04 first with the Live USB and no permanent install and it worked fine. Unfortunately I didn't make the install from the Live USB, but started over and used the "go direct to install without trial" option, which was a mistake. I set up encryption. The install went without any problems. I then rebooted at the requester. The system seems to be starting fine, but it is stuck first with a backlit blank screen with a frozen cursor mid-screen. Then, obviously after following a programmed time, the screen goes completely black, with no back lighting evident. My problem also is that the Mac efi boot option menu will no longer appear, when I hold the appropriate key after the chime on start-up, so I can do a re-install. I can't reset PRAM either.

I have reviewed the sticky on this forum, done numerous searches and tried every suggestion: shift, esc, etc. Thinking that my keyboard may not be functioning, I have a new one ordered, but doubt it will accomplish anything.

Any help appreciated. Thanks in advance.
