System Installation – Installing Ubuntu on the VM

I was able to boot and install Ubuntu 18.10 Desktop on VM Workstation Pro 12. Ubuntu has been updated, and it does not become a cmd check-up window when booting, so it just sits there and does nothing. Enter the image description here

Is there something I should do or watch?
The CD / DVD drive is not connected – I even removed it from the settings. When it starts up, the Ubuntu logo will appear for a few seconds and then back to the cmd checklist. Nothing happens in the cmd checklist, I can restart it, but that's it.

Design Patterns – Log in as the first step after installing the app

What are the arguments that prompt users to log in before they can use your app?

For example, if you have downloaded your app from a secret luxury accommodation booking site, you will need to create an account. It is important to mention that the website only mentions the service.

I suspect that users will be shown a little bit before being asked to create an account by code review.

Installation – Installing the dependency of the Python library without available Internet

I'm trying to install the following package (SignXML) on Windows Server 2012:

I'm using Python 2.7.14, it's an isolated server that can only be accessed inside the intranet and blocks all outgoing connections.

I downloaded tar.gz from this package and ran: "pip install signxml-2.6.0.tar.gz".

The installation was started, but I get an error message:

Repeat (Repeat (total = 4, Connect = None, Read = None, Forward = No))
interrupted after connection
& # 39; ConnectTimeoutError (, & # 39; connect with
pypi.python. org has expired. (Connection timeout = 15) & # 39;; & # 39 ;: / simple / lxml /

I am not an expert on Python, but due to errors I assume that I will try to retrieve dependencies on pypi, but they will fail because the outgoing connections are blocked.

Is there a way to view all dependencies for this project (SignXML) and manually download them as tar.gz archives and then somehow manually install or instruct the SignXML installation to use local files instead of getting them from Pypi?

I can not start my Windows SSD after installing Ubuntu 18.04 LTS

I hope someone can point me in the right direction here before I have to go nuclear and just reinstall everything. I tried to search and just can not find a suitable answer to my problem. Some time ago (6 months ago) I bought a 500GB Samsung SSD. I have Windows 10 installed on it, but left my original Windows 10 operating system on the hard drive that came with my desktop. I wanted to wait and make sure I had everything from the hard drive I needed before using it for storage or some other reason.

Well, after installing Windows 10 on my SSD, I always had a choice of which hard drive to boot from each time I restarted my computer. I decided a few days ago to download Ubuntu (18.04 LTS) to the hard drive and install and leave Windows 10 on the SSD. The installation went fine, but now my computer boots directly into Ubuntu. I have no choice of which hard drive I want to boot.

I read that before installing Ubuntu, you should unplug the Windows 10 SSD before installing Ubuntu on a second hard drive. So I tried. I installed the Win 10 SSD d / c, reinstalled Ubuntu, re-connected my Win 10 SSD, booted the PC in Ubuntu, went to the terminal and did os-prober, but nothing happened (there was a break when I wanted to the computer did something, but then I was just presented with a new terminal line), then also sudo update-grub and the Linux information was displayed, but no Windows information was displayed.

Have I messed up the puppy here completely or is there a chance I can do something about it? Many Thanks.

Do I have to remove my current Nvidia drivers before installing new ones?

I'm using Ubuntu 18.04 on a hybrid Nvidia laptop with the Ubuntu-packaged Nvidia 390 drivers. I would like to upgrade to the version 410 drivers. So I added the video drivers PPA and tried to install them. Everywhere I've found online, it's been suggested that this is all you have to do. Instead, apt called to a series of dependency issues that would cause the installation of the new drivers:

$ sudo apt install nvidia-driver-410
Read package lists ... Done
Create dependency tree
Status information is read ... Done
Some packages could not be installed. This can mean that you have
Requested an impossible situation or if you use the unstable
Distribution that some required packages have not yet been created
or has been moved from Incoming.
The following information may help correct the situation:

The following packages have unfulfilled dependencies.
nvidia-driver-410: Dependent: libnvidia-gl-410 (= 410.78-0ubuntu1 ~ gpu18.04.1), but it will not be installed
Depends on: nvidia-dkms-410 (= 410.78-0ubuntu1 ~ gpu18.04.1), but it will not be installed
Dependent: nvidia-kernel-source-410 (= 410.78-0ubuntu1 ~ gpu18.04.1), but it will not be installed
Dependent: libnvidia-compute-410 (= 410.78-0ubuntu1 ~ gpu18.04.1), but it will not be installed

Recommends: libnvidia-ifr1-410: i386 (= 410.78-0ubuntu1 ~ gpu18.04.1)
E: Problems can not be solved. You have stored defective packages.

The problems look real – Giftedness why not says that the 390 drivers (directly or indirectly) conflict with almost every part of the 410 drivers. In this case:

  • Do I have to uninstall the 390 drivers before installing the 410 drivers? (probably something similar apt purge nvidia-driver-390 && apt autoremove --purge?)
  • Is this safe when using the Nvidia GPU? What do I do if I can not install the new drivers?

System Installation – I have updated the bios, but still get an error installing Ubuntu

I've been trying to install Ubuntu alongside Side 10 on my Dell laptop for days, but failed. I received an errata bug where I should update the microcode. After reading some solutions, I was able to update the BIOS to the latest version. I also partitioned one of my hard drives (F) and assigned over 70 GB. Still, I still can not install Ubuntu with a bootable USB stick. If I boot my computer via USB, the process will start, but an error will be displayed stating that the microcode needs to be updated. Then it automatically skips the next page, where I want to install or try Ubuntu. I click on "Install". The installation continues, but when it reaches the menu where I should select "Install next to Windows," this option is not available. Instead, I have 3 options. Install Ubuntu and delete the windows. and other options, but I do not have the option to install along windows. Please help How do I do that?

Windows 7 – After installing KB4480970, I can not access shared folders or printers

This is a known issue that was caused by the Windows Update KB4480970, January 8, 2019. According to Microsoft, this update introduces the following problem:

Local users who are part of the local Administrators group may be unable to remotely access shares on Windows Server 2008 R2 and Windows 7 computers after installing the security updates on January 8, 2019. This does not affect domain accounts in the local Administrators group.

On January 11, Microsoft released the hotfix KB4487345 to correct this problem:

This update resolves the issue where local users who are part of the local Administrators group might not be able to remotely access shares on computers running Windows 7 SP1 and Windows Server 2008 R2 after installing security updates on January 8, 2019. This does not affect domain accounts in the local Administrators group.

This hotfix is ​​not distributed through Windows Update. Instead, you must download it directly from the Microsoft Update Catalog Web site.

Install this hotfix on the computer hosting the network shares that users can not access. According to my tests, it is not necessary to install it on computers from which tries to access the shared folders or printers.

The APFS volume does not start after installing the mouse driver

The iMac recently upgraded to High Sierra while migrating the boot volume to APFS. Installed compatible driver for my Evoluent mouse (which had asked for a security risk) and after the restart Mac stopped at the bottom of the startup status bar. Force restart. The same. Safe start. The same. Start in verbose mode Attached screenshot shows what I see.
Enter the image description here
APFS error in detail

It comes in the expected time on the line in the top line, in which "apfs_vfsoop_unmount: 1846 everything is ready to go home" is displayed, but then a few minutes in the next line over the AppleKeyStore and the special bag -503 stops , then a few more minutes until the & ap; apfs_keybag_get: 1320: apfs volume keybag, err = 2 & # 39; failed. The remainder showed up in the next 30 to 40 minutes, apparently looking for snapshot data.

Can someone understand that? Is there a way to fix this APFS error? How can installing a driver damage APFS to this extent?

I was able to boot into recovery mode and reinstall the operating system, so I usually ask for wisdom about APFS pitfalls?
