Select Kernel Installer

[Valtam]

This is a very simple kernel installer I've started working on. At this stage, I haven't decided if this will develop into a LL package, but people have asked for it.

The code so far:

Code:

#! /bin/bash
#--------------------------------------------------------------------------------------------------------
# Name: Lite Kernel Select
# Description: Select a Linux Kernel to install on Linux Lite.
# Authors:  Jerry Bezencon
# Website: https://www.freecinema2022.gq

# Ensure multi-language support
export LANG=C

# Kill off any package managers that may be running
if [ "$(pidof synaptic)" ]
then
   sudo killall -9 synaptic
fi

if [ ! -z "$(pgrep gdebi-gtk)" ]
then
   killall -9 gdebi-gtk
fi

    sudo apt-get update 2>&1 | awk -v total=$APTUPDATE '/^Ign|^ Get/{count++;$1=""} FNR { if (total != 0){percentage=int (100*count/total);print (percentage < 90?percentage:90),"\n#",substr($0, 0, 128) }; fflush(stdout)}' \
      | zenity --progress --text="Updating package lists..." --window-icon=$ic --title="Updating Software Sources - please wait..." --percentage=0 --auto-close --width=600

Open a terminal:

Code:

touch kernelinstaller

copy the above code into kernelinstaller (open kernelinstaller with a Text Editor). Now save the file.

Code:

chmod +x kernelinstaller
gksudo ./kernelinstaller

There is no end dialogue, when the Zenity message has closed, you can reboot.

This is very Beta and as such, should only be installed in a VirtualBox. When you reboot, hold down Shift key to bring up Grub, go to Advanced, and you should see the Kernel in the list, select it and press enter.

To dos:

- Initial window "Install Kernel" and "Remove Kernel" select list
- Confirm kernel is installed dialogue
- Better output in zenity, percentage of install process (similar to updates-gui)
- Move just installed kernel to the top of the list in Grub before rebooting

You can use grub-customizer for now to move the kernel you chose to install, to the top of the Grub list.
Use Lite Tweaks to remove any kernels for now.
