Problem to install qmi_install.sh (unzip: not found)

Hello all,

I have successfully installed qmi with a Raspberry as I discribed here (Sorry, it in french) following this doc

Now, I add a LoRaWAN hat.

Until all work fine, but I trying to install qmi

mkdir ~/Soft cd ~/Soft
mkdir sixfab
cd ~/Soft/sixfab
wget https://raw.githubusercontent.com/sixfab/Sixfab_RPi_3G-4G-LTE_Base_Shield/master/tutorials/QMI_tutorial/qmi_install.sh 
sudo chmod +x qmi_install.sh
sudo ./qmi_install.sh

I have not experiment an issue, previously, but now,I got this error

drivers.zip 100%[======================================================>] 99.17K 204KB/s in 0.5s

2020-04-01 00:02:58 (204 KB/s) - ‘drivers.zip’ saved [101553/101553]

./qmi_install.sh: 41: ./qmi_install.sh: unzip: not found

and then

Copying udhcpc default script
cp: cannot stat ‘/home/pi/files/quectel-CM/default.script’: No such file or directory
chmod: cannot access ‘/usr/share/udhcpc/default.script’: No such file or directory
Change directory to /home/pi/files/drivers
./qmi_install.sh: 55: cd: can’t cd to /home/pi/files/drivers
make: *** No targets specified and no makefile found. Stop.
Change directory to /home/pi/files/quectel-CM
./qmi_install.sh: 59: cd: can’t cd to /home/pi/files/quectel-CM
make: *** No targets specified and no makefile found. Stop.
After reboot please follow commands mentioned below
go to /home/pi/files/quectel-CM and run sudo ./quectel-CM -s [YOUR APN]

It’s look like if it can not find drivers.zip and /home/pi/files can not be create.

I also deleted /Soft/sixfab and repeat the operation in /home/pi, without succes

Any idea, what happened and how to solved?

Cheers

Problem solved. Unzip was not installed
