I followed this step to install ubuntu, and then finished running the script. What's the situation that pnet doesn't appear after restarting?

📀 Installation instructions - PNetLab v6 BETA release
⚠️ Read the full instructions and important notes before starting the process. After you finish reading them, follow the process step by step.
Step 1
Download the Ubuntu Server 20.04 ISO and install the OS on a VM or bare metal.
Step 2
Run the installation script as root (copy-paste the full thing):
curl -sL https://labhub.eu.org/api/raw/?path=/UNETLAB%20I/upgrades_pnetlab/Focal/install_pnetlab_v6.sh | bash
After the installation script finishes running, reboot the server.
ℹ️ Important notes
- Make sure to enable Virtualization on your system BIOS and make sure your hardware supports nested virtualization.
Check if you meet the requirements by running:
grep -cw vmx /proc/cpuinfo
Check if KVM was installed correctly after the installation script finishes running:
kvm-ok
- When installed on GCP, skip the setup wizard by pressing CTRL + C after the first reboot and if you're tired of having to do that at every login, ask how to disable in this chat.
⚠️ Remember this version is still on beta so you might encounter bugs and unfinished features.

If you are facing this error when trying to install a package through APT, it means your apt package manager configuration is broken.
ishare.top is the domain name that was used by the now dead ishare tool. To fix this error, delete it from the sources.list file.
Through the CLI run:
nano /etc/apt/sources.list
Once you have entered the editor, remove the ishare.top line from the list.
Check how to use nano
(Navigate with arrow keys. CTRL+s to save changes, CTRL+x to exit)
If you want to use a reborn of ishare, send #ishare2 to this chat to get the installation instructions.
