I recently installed Ubuntu 20.04.5 on my MacbookPro (Early 2015) to work on my University internship project, and I am trying to connect a RedPitaya FPGA Board as per the instructions.
It is supposed to work simply by plugging in and then going to the address of the device rp-xxxxxx.local/ . I am using a Benfei USB Ethernet adapter whose drivers I downloaded from their official website. It seems the ethernet driver 'r8152' is already supposed to be preinstalled with Ubuntu 20.04 but since my device was stuck on 'connecting' and never actually connected I downloaded the drivers from the website.
It was in a .tar file and I installed it as per the following :
Extracting the files
tar -xf r8152.53.56-2.14.0.tar
I changed the directory this is the list of files that were extracted :
50-usb-realtek-net.rules compatibility.h Makefile r8152.c ReadMe.txt
In the above directory I ran the command
make
After that the directory had the following files :
50-usb-realtek-net.rules Makefile Module.symvers r8152.ko r8152.mod.c r8152.o
compatibility.h modules.order r8152.c r8152.mod r8152.mod.o ReadMe.txt
Then I finally ran the command
make install
But i got following error
rmmod r8152
rmmod: ERROR: ../libkmod/libkmod-module.c:799 kmod_module_remove_module() could not remove 'r8152': Operation not permitted
rmmod: ERROR: could not remove module r8152: Operation not permitted
make: *** [Makefile:36: install] Error 1
Then i tried to do the following
sudo make install
And this was the result
rmmod r8152
make -C /lib/modules/5.4.0-139-generic/build M=/home/sourabh/Downloads/r8152-2.14.0 INSTALL_MOD_DIR=kernel/drivers/net/usb modules_install

modprobe r8152
And I also executed the following because they were recommended in the ReadMe.txt file
sudo depmod -a
and
update-initramfs -u
with output
update-initramfs: Generating /boot/initrd.img-5.4.0-139-generic
After all this, it seemed that the installation was done correctly but still every time I try to connect the device, it gets detected, it has the status 'connecting' for a while and then it fails to connect.
I am sure that there is no fault with the device because it connects and works fine with on MacOS. I request you to please help fix this.
I am not sure what I am doing wrong, please help me fix this so I can connect to the device.
Following up with some more information :
I ran the following command
sudo nmcli connection show
which gave the following output
NAME UUID TYPE >
Wired connection 1 37aafbb6-84cd-4ffc-a034-4a31be5f2173 ethern>
Sharies 17791b79-91f9-4691-908f-9cb2ade1685f wifi >
and then I ran the command
sudo nmcli connection up "Wired connection 1"
which gave error
Error: Connection activation failed: IP configuration could not be reserved (no available address, timeout, etc.)
Hint: use 'journalctl -xe NM_CONNECTION=37aafbb6-84cd-4ffc-a034-4a31be5f2173 + NM_DEVICE=enx3c18a0d4d71a' to get more details.
