Creates corrupt .INSTALL script

[latekvo]

I will follow up on this later but Im running late today and just wanted to report as much as i remember for today.
When i used debtap on Cisco packet tracer 8.2.1-1 debian package, the install script that had been generated was missing line 20 causing pacman to crash during the install with this error:

/tmp/alpm_qPMsyx/.INSTALL: line 20: syntax error near unexpected token `else'
/tmp/alpm_qPMsyx/.INSTALL: line 20: `	    else'
/usr/bin/bash: line 1: pre_upgrade: command not found
error: command failed to execute correctly

context:

pre_install() {
	STATE=1 
	while [ "$STATE" != 0 -a "$STATE" != 4 ]; do
	    case "$STATE" in
	    1)
	    ;;
	    2)
	    ;;
	    3)
	        if [ "$RET" = "false" ]; then
	            exit 1
	        fi
	    ;;
	    esac
            # here is the missing IF statement
	        STATE=$(($STATE + 1))
	    else
	        STATE=$(($STATE - 1))
	    fi
	done
	exit 0
}

I later determined the missing statement has to be

        if [ "$STATE" -eq 3 ]; then

Please ask me for any missing details.

Hello I wanted to follow up,
during the install, there was one more error in the .INSTALL script, but it didn't prevent packettracer from installing.

gtk-update-icon-cache: No theme index file.

I confirm that after making the changes i made to the .INSTALL script, the program installs and runs as expected.

Hi, thank you for maintaining this repository!

I encountered a similar issue when I converted beam-studio_2.3.9_amd64.deb (https://flux3dp.com/downloads/).
I tried the following command, but the installation with the converted file failed.

sudo debtap beam-studio_2.3.9_amd64.deb
sudo pacman -U beam-studio-2.3.9-1-x86_64.pkg.tar.zst 

Result:
