[I cannot get flirc installed on my linux machine]

I have simmilar problem using curl instaling version on Ubuntu 22.04 64bit. Script successful executed, but nothing was installed. (I think the repo is broken or unavailable)

Then I tryed manual install from sources with success :

1. https://flirc.com/ubuntu-software-installation-guide - download Latest Archive 64bit

2. Unzip and copy flirc_util and Flirc files to /usr/local/bin/

3 In directory /etc/udev/rules.d create new file and name it 99-flirc.rules. Paste bellow content:

# Flirc Devices

# Bootloader
SUBSYSTEM=="usb", ENV{DEVTYPE}=="usb_device", ATTR{idVendor}=="20a0", ATTR{idProduct}=="0000", MODE="0666"
SUBSYSTEM=="usb", ENV{DEVTYPE}=="usb_device", ATTR{idVendor}=="20a0", ATTR{idProduct}=="0002", MODE="0666"
SUBSYSTEM=="hidraw", ATTRS{idVendor}=="20a0", ATTRS{idProduct}=="0005", MODE="0666"

# Flirc Application
SUBSYSTEM=="usb", ENV{DEVTYPE}=="usb_device", ATTR{idVendor}=="20a0", ATTR{idProduct}=="0001", MODE="0666"
SUBSYSTEM=="usb", ENV{DEVTYPE}=="usb_device", ATTR{idVendor}=="20a0", ATTR{idProduct}=="0004", MODE="0666"
SUBSYSTEM=="hidraw", ATTRS{idVendor}=="20a0", ATTRS{idProduct}=="0006", MODE="0666"

4. Restart computer

5.When I try to start  Flirc I got libreadline.so.7 missing dependencies error. In Ubuntu 22.04 is now version libreadline.so.8 installed so I crate symlink :

sudo ln -s /lib/x86_64-linux-gnu/libreadline.so.8 /lib/x86_64-linux-gnu/libreadline.so.7

6. Install other dependencies. (not all will  install, but don't afraid  and continue)

sudo apt install libhidapi-hidraw0

sudo apt install libqt5core5a

sudo apt install libqt5network5
sudo apt install libqt5xml5  
sudo apt install libqt5xmlpatterns5  
sudo apt install libhid 
sudo apt install qt5-qtbase 
sudo apt install qt5-qtsvg 
sudo apt install hidapi

7. Start configuration program using sudo command (without sudo program starting, but throw errors) :

sudo Flirc
