I have the need to use the older python 2.7 with numpy for a Spark project on EC2 ubuntu 22.04. These were what I did ...

 sudo apt update
 sudo apt install python2.7
 sudo apt-get install python-numpy

The last step got an error "E: Unable to locate package python-numpy".

Any suggestions on to fix the problem?

maybe this had been already answered with a different title, but I did not find the thread.
The setup:

  1. User test1 created on setup
  2. User newUser1 added afterwards
  3. User newUser1 runs "pkexec somecommand" and the system asks for the password of user test1

I checked /etc/polkit-1/ , but no configuration file exist in this structure.
Why does pkexec asks for the password of test1?
It should ask for the password of newUser1. Or do I understand something wrong?

I think I screwed it up when tried to install Network Manager over networkd running service. I have Ubuntu server installed on a brand new Raspberry PI 4 with only 1GB of ram, hence 'server'...

Much of the answers seen around are for Network Manager which is installed on desktops.

Uninstalling Network Manager didn't work. I think I did it. Hard to be sure.

Both interfaces, eth0 and wlan0 show same behavior. Up with IP address and all, but no internet connection .

netplan status shows both IP address and default route assigned.

Ping success over local phone or router.

---> PING SUCCESS TO UBUNTU.COM. OR GGL.<---

Any thoughts?

My host machine is a dedicated windows server. I installed Oracle VirtualBox with VM running Ubuntu 24.04.1 LTS.

I have internet access using NAT. But the problem is I need the Ubuntu VM to have a static IP (can be the same as the Windows Server).

My end goal is to turn the VM into a self hosted Ubuntu GitHub action runner with a static IP to get through a firewall.

I have spent about 6+ hours trying to get the network connection working with no luck. I switched the connection to bridged, but no matter how I configure it I can't access the internet on the VM.

Not sure if this is relevant, but my host machine's ethernet adapter has 'DHCP Enabled: false'. From my understanding, if I am using a static IP I will not be using DHCP. Any help is appreciated.

Python reported a problem with MESA-Loader so I and ran the following commands on Ubuntu 24.04 LTS (to be honest, I did not really know what I was doing):

dpkg -l | grep mesa
sudo apt remove --purge libgl1-mesa-dri
sudo apt install libglu1-mesa
sudo apt install libgl1-mesa-dri
sudo apt install mesa-utils

Now, I am only seing the command line and no graphical interface on the machine.

All I want is getting back the graphical interface (reverting above commands)

What I tried:

sudo apt update
sudo apt upgrade
sudo apt install libgl1-mesa-dri
sudo apt install mesa-utils
sudo reboot

Which did not help. When I do dpkg -l | grep mesa I get:
