apt – Error installing lutris with the linux terminal

Try this:

sudo apt-get update && sudo apt-get upgrade
sudo apt-get install
Software features common

If this does not work (due to a legacy Ubuntu release), try the following instead:

sudo apt-get update && sudo apt-get upgrade
sudo apt-get install
Python Software Features

In any case, you should then do the following:

sudo add-apt-repository ppa: lutris-team / lutris
sudo apt-get update
&& sudo apt-get upgrade
sudo apt-get install lutris

scripting – How do I fix the error of a function?

I am writing this function, and when I run it, it means that the function has no opening. If I remove the right square bracket, the error "needs more input" will be displayed.

PlaneTrussElement(e_, A_, {{x1_, y1_}, {x2_, y2_}}) := Module({ls, ms, L}, L = Sqrt((x2 - x1)^2 + (y2 - y1)^2);

ls = (x2 - x1)/L;

ms = (y2 - y1)/L;

e*A/L {{ls^2, ls*ms, -ls^2, -ls*ms}, {ls*ms, ms^2, -ls*ms, -ms^2}, {-ls^2, -ls*ms, ls^2, ls*ms}, {-ls*ms, -ms^2, ls*ms, ms^2}})

PlaneTrussElement(29000000, 1.73, {{-60, 420}, {-180, 480}})

If I execute the above line, no matrix will be returned for me.

How do I solve this?

I get this error in GodOt and can not fix it "Error (45,74): The identifier" collision "is not declared in the current scope

direction = direction.normalized ()
direction = direction * speed * delta

    velocity.y += gravaty * delta
    velocity.x = direction.x
    velocity.z = direction.z

    velocity = move_and_slide(velocity, Vector3(0, 1, 0))

    if collision.collider is RigidBody:
        collision.collider.apply_impulse(collison.position, -collision.normal)

updates – Error 500 when updating the plugins

I encounter this bug when updating plugins:

Update failed: 500 Internal server error Internal server error The server has detected an internal error or an incorrect configuration and could not complete your request. Contact the server administrator at webmaster@xn--qucu-hr5aza.cc to notify him of the time of the error and the actions you took immediately before this error. You may find more information about this error in the server error log.

That was a week ago, so I do not think it's the problem of the busy server. I opened the log and found nothing new. I put WP_DEBUG too true and that's what I got:

Warning: An unexpected error has occurred. There may be a problem with WordPress.org or the configuration of this server. If you continue to have problems, try the support forums. (WordPress was unable to establish a secure connection to WordPress.org. Contact your server administrator.) In /home/lightnin/domains/xn--qucu-hr5aza.cc/public_html/wp-includes/update.php on line 384

Since I did not touch anything in wp-includes, I do not know why that happens. After I received this message, the plugins were updated.

So this problem is solved, but I wonder if anyone can provide more insight into this.

postgresql – ERROR: The check condition "dates_check" is violated by one line

ALTER table myTable ADD CONSTRAINT dates_check CHECK(start_date::date < end_date::date);

Gives ..

But..

select start_date, end_date from myTable where start_date::date > end_date::date;

Returns..

Windows 7 – Ping the DC IP address and connect to the domain will not result in an error (

I have set my Windows 10 DC to a static IP address and this is as follows:

  • IP: 192.168.2.2
  • Subnet mask: 255.255.255.0
  • Default Gateway: 192.168.2.1
  • Preferred DNS server: 192.168.2.2
  • Alternate DNS server: None

And with a connected Windows 7 device via:

  • IP: 192.168.2.11
  • Subnet mask: 255.255.255.0
  • Default Gateway: 192.168.2.1
  • Preferred DNS server: 192.168.2.2
  • Alternate DNS server: 127.0.0.1

IPconfig for my DC
IPconfig for my Win7 device

I can not seem to send the client to my domain controller or connect to the domain. On my DC it seems to recognize the name of my DC, which for private reasons will be called "foo.net". What did I do wrong? I'm really at a loss at this point. This runs on Oracle VirtualBox 6.0.12.

To edit:
Both VMs are running on the same machine, and both are running on the NAT connection type, as opposed to bridged.
