Error in brug installation

I’m using Linux Mint 19 Chinnamon, try to install brug with this ppa:

sudo add-apt-repository ppa:n-muench/ppa 

It shows error:

HTTP Error 404: Not Found Cannot add PPA: ''This PPA does not support bionic'' 

There is no 404 error in other this, any idea how to solve this.

NVIDIA Driver Installation Issue (Not able to Install latest version) GTX 1060 Zotac

So, whenever i tried to install NVIDIA driver through software and updates application, I used to get blank screen while booting through normal mode.

latest driver for NVIDIA is 418 so far, but in the update menu it just shows up driver version 390.

My questions:

How do i get rid of blank screen while booting?.

Is there any other reliable source to install NVIDIA driver with latest updates?.

Is that okay to run GPU without native it`s driver configuration?.

Possible to install packages to a separate Linux installation?

So I was trying to get a CentOS designed application to work on Ubuntu, and played around with some graphics drivers. Well, in my spree of copy and pasting SE suggestions into my terminal, I broke something bad. I no longer have any GUI, and am stuck in tty. Trying to run startx tells me that /usr/bin/X doesn’t exist. Awesome. I think I could fix it with

sudo apt-get install --reinstall ubuntu-desktop

but I can’t do this because I have no internet connection from tty, and cannot find any working solution to get wifi connected using wpa_supplicant, or anything else. As far as I understand, recovery mode will be useless too, without an internet connection.

So, instead I installed an Ubuntu 16.04 image onto a USB stick, and booted from there (which is what I’m typing this post from). Here, I have access to all my files, great, and have GUI and internet connection working fine.

Now, is there a way for me to repair my original Ubuntu while having booted from the USB? I don’t really know how apt-get works, but I would imagine there should be some way to download the ubuntu-desktop files while I have internet connection, and then reboot into my original Ubuntu’s tty, and do the install. No? Suggestions?

Edit:

Okay, I can

sudo apt-get install --download-only ubuntu-desktop --reinstall

to get the deb package file onto the live-usb. Now figuring out how to move it to my machine/access it from my other installation…

Unable to install Ubuntu 18.04 after cancelled installation

I was attempting to install Ubuntu however halfway through the menus asking me to select the what types of files I would like to install I decided to cancel the installation by clicking the cancel button on the bottom of the window, I assumed I could come back to the installation at a later time however when I attempted to boot using the disk I had used flawlessly before. I was met with a message detailing that it;

Failed to open \EFI\BOOT\mmx64.efi - Not Found Failed to load image \EFI\BOOT\mmx64.efi: Not Found Failed to start MokManager: Not Found Something has gone seriously wrong: import_mok_state() failed : Not Found

I attempted to wipe my computer clean so I reset the computer to factory settings five times with each attempt failing to correct the issue. I am wondering if there is a way I can fully remove the corrupted pieces and attempt a clean installation of Ubuntu from the disk since I don’t have any free usb’s lying around. P.S. I am attempting to set up my computer so that it can dual boot. Thank you for your time.

Recommended manner of installation for an open source web application and api?

I’m currently working on my own open source project.

There are two parts to it at the moment, a .NET core web API and an Angular client side app.

I would like to get your views on installation/setup for my users. What I have at the moment is an install endpoint in the API itself and an install component/page on the angular app.

This all works well but after giving it more thought it doesn’t feel right. It feels I’ve ended up coupling the app and API when they should be completely separate and independent of each other. The client app should not really have to be concerned with the installation of the API.

Would it be better to build a CLI responsible for installing/upgrade both the API and APP that can be downloaded and run separately?

Ubuntu very laggy after some software installation and uninstallation

I uninstalled and installed some NVIDIA/Cuda related stuff (e.g., drivers, CUDA 10.0, previously used CUDA 10.1, libcudnn). I did all of this through ssh. I just logged onto my physical machine and it is very laggy. Typing text is very noticeably laggy.

In some searches on here users suggested to turn off animations on Ubuntu. I tried that and it didn’t improve the performance.

Below are some outputs. Is the amount (~600mb) of memory being used by xorg normal? compiz appears to be using a lot of CPU. Is this normal? What other testing could I conduct to identify other issues that may be causing the slowdown?

Here are some outputs that may be useful:

New PC fails EFI-boot on USB installation xUbuntu-18.04; BIOS boots USB

New Acer-PC Aspire-T Intel i5 core processor 8400 internal memory 8 Gb DDR4 250 Gb Solid-State-Disk 2 Tb sata-Disk

USB-installation medium several times used: always successful on BIOS-boot. If the PC boots in BIOS-mode, then the USB-installation can be started, but then the GUID-partitions show up as undefined. This is normal. If the PC boots in UEFI-mode, then the only boot-choice is to start the Micr$ oft Windblows-installation, this is not what we want to happen.

2 questions:

.q1. How do we get this PC to boot in UEFI-mode and start xUbuntu-installation using the USB-stick ? … without having to do the W-installation first.

.q2. Any suggestions for a clever Partition-set: must we use the Solid-State disk as * boot, * root, * swap ?!?

I assume your answer will look like:

  • Solid-State p1: Guid-Efi-Partition (1 Gb fat-32; necessary for UEFI-boot)
  • Solid-State p2: root (240 Gb ext4)
  • Solid-State p3: swap-Partition (14 Gb swap)
  • 2 Tb p1 : home-partition (ext4)

On the web several completely suggestions are found. None of them worked for UEFI-booting the USB-installation.

We appreciate your time and suggestions!

Homebrew Cask: List all formula available for installation

After updating the local Homebrew cache by running brew update, I have been using brew search and brew cask search to list all the available formula for installation via Homebrew Core and Homebrew Cask respectively. Note that skipping the argument after search does the trick of listing all the formula available for installation.

While brew search still works, this is no longer the case with Homebrew Cask. Instead, now running brew cask search displays the explanatory text:

Homebrew Cask provides a friendly CLI workflow for the administration of macOS applications distributed as binaries.

followed by a list of available Homebrew commands.

What command one need to run, to get a list of all the formula available for installation via Homebrew Cask?

While it is still possible to navigate to:

/usr/local/Homebrew/Library/Taps/homebrew/homebrew-cask/Casks

and obtain the desired list, I am looking for a solution along the lines of previously working brew cask search.

I am running up-to-date version of Homebrew (Homebrew 2.0.4) on macOS Mojave 10.14.3 (18D109).
