Unable to cd to iscsi mounted drive
in flag

I am new to the Ubuntu environment. I have been a RH user for 20 years.

In a new install of 18.04 in VMWare 6.5U3 environment, the server will store security camera data.

I've attached Synology storage to VMware and the client server (the Ubuntu itself is on local storage).

When I mounted the video storage it showed up as /dev/sb1. The local path is /mnt/edvr/1. I am unable to cd into the edvr or

Nvidia driver issues persistent across multiple versions of ubuntu - unbootable OS

On June 6th after installing a software update, nothing on steam was able to launch, so I rebooted my PC. after that point, it consistently got stuck on the motherboard logo when trying to boot the OS. I was able to recover my files by using an older version of the kernel that forced llvmpipe. This was on 20.10.

recover from shim fail after change from grub2 to shim in 18.04 can not login
co flag

Apparently, ubuntu 18.04 has decided to make system changes without asking.

One of these was a change from Grub2 64 bit which was fine, to shim which has now locked up my computer and made it unusable. Login does not work. Boot gives error message "failed to set moklistrt"

Since I can not login, how can I use live boot cd to repair this?

"Please check your Internet connection" box will not go away
ph flag
mpd

This box

This box cannot be removed in any way I've tried so far. I'm sure a reboot would fix it (it has before), but is there a way to get rid of this thing without rebooting?

My connection is fine, and I've restarted networking multiple times.

This thing is covering up the bottom line in my terminal, and it's really frustrating.

So basically i have FOG setup to currently boot windows mdt isos.

Ive been working the last few months via trial and error to get this working for Ubuntu.

Ubuntu fully works properly via vmware virtual machines because built-in network adapters are no problem.

When i go to take the public initrd and vmlinuz files from the public ISO and boot them to the usb-c adapters on the laptops. 2 things happen

Serial device stops working when upgrade to 20.04

I have a USB device with a serial interface. It worked great on 18.04 (and on Windows) but when I upgrade to 20.04 something is interfering with communications.

When I plug in the device, it shows up as /dev/ttyACM1 or /dev/ttyACM0, which is what I expect.

When I look at /var/log/syslog I see this :

The Stunning Power of Questions

Much of an executive’s workday is spent asking others for information—requesting status updates from a team leader, for example, or questioning a counterpart in a tense negotiation. Yet unlike professionals such as litigators, journalists, and doctors, who are taught how to ask questions as an essential part of their training, few executives think of questioning as a skill that can be honed—or consider how their own answers to questions could make conversations more productive.

That’s a missed opportunity. Questioning is a uniquely powerful tool for unlocking value in organizations: It spurs learning and the exchange of ideas, it fuels innovation and performance improvement, it builds rapport and trust among team members. And it can mitigate business risk by uncovering unforeseen pitfalls and hazards.

For some people, questioning comes easily. Their natural inquisitiveness, emotional intelligence, and ability to read people put the ideal question on the tip of their tongue. But most of us don’t ask enough questions, nor do we pose our inquiries in an optimal way.

The good news is that by asking questions, we naturally improve our emotional intelligence, which in turn makes us better questioners—a virtuous cycle. In this article, we draw on insights from behavioral science research to explore how the way we frame questions and choose to answer our counterparts can influence the outcome of conversations. We offer guidance for choosing the best type, tone, sequence, and framing of questions and for deciding what and how much information to share to reap the most benefit from our interactions, not just for ourselves but for our organizations.
