Failed to execute command "/usr/bin/pijuice_gui" #648

Open ro0TuX777 opened 3 years ago

ro0TuX777 commented 3 years ago

Complete error message when attempting to load it from the menu: _Failed to execute child process "/usr/bin/pijuicegui" (No such file or directory)

Complete error message when attempting to load it from the terminal window: _bash: /usr/bin/pijuicegui: No such file or directory

About the computer: Kali version 2021.1 Kernel: Linux 4.19.118-Re4son-vl+ Architecture: arm uname -m: armv7l

Within the /usr/bin folder the following pijuice files exist: pijuice_cli, pijuice_gui, pijuice_sys.pi, pijuice_tray.py, pijuiceboot

Instructions followed: https://github.com/PiSupply/PiJuice/issues/405

Update sudo apt update then install dependancies sudo apt install i2c-tools sudo apt install lua5.3 Add user root to group pijuice run sudo visudo add root ALL=(pijuice) ALL save and exit. Clone the repository git clone https://github.com/PiSupply/PiJuice.git install pijuice base from cd PiJuice/Software/Install run dpkg -i pijuice-base_1.5_all.deb Fix broken packages with sudo apt --fix-broken install reboot and you should be able to run pijuice_cli from the terminal.

Once pijuice-base has been installed you can then install the GUI by running dpkg -i pijuice-gui_1.5_all.deb GUI requires Python3-tk install with sudo apt --fix-broken install reboot. PiJuice will be added to the application menu and you can run from there or from terminal with pijuice_gui.

Something went wrong with the installation. In /usr/bin I am missing pijuice_cli.py and pijuice_gui.py. Also current version of the packages is 1.6 and not 1.5.

ro0TuX777 commented 3 years ago

I get the same error message with 1.6 as well.

tvoverbeek commented 3 years ago

In a terminal window on the desktop what is the output from `ls -l /usr/bin/pijuice*? Here is what I get:

-rwxr-xr-x 1 root    root     20344 Feb  6  2020 /usr/bin/pijuiceboot

What error message do you get when running from a terminal window /usr/bin/pijuice_gui?

ro0TuX777 commented 3 years ago

Um, mine looks a little different.

pijucerights

do I just chmod +rwx the files? if so, what would that be?

tvoverbeek commented 3 years ago

The permissions look fine. No need to change anything there. What error message do you get if you run /usr/bin/pijuice-gui in a terminal window? Does running /usr/bin/pijuice_cli in a terminal window work?

ro0TuX777 commented 3 years ago

Complete error message when attempting to load it from the terminal window: bash: /usr/bin/pijuice_gui: No such file or directory

Same for thr cli

tvoverbeek commented 3 years ago

OK. Next test: In a terminal window: sudo -u pijuice python3 /usr/bin/pijuice_gui.py. Should produce python3 error messages which might help us.

ro0TuX777 commented 3 years ago

tvoverbeek commented 3 years ago

This helps. What version of python3 are you running on Kali? (python3 --version) Is it 3.9? The thread method isAlive() was deprecated in python 3.x and replaced by is_alive() Both versions were supported from 2.6 till 3.8. isAlive() has been removed in 3.9.

ro0TuX777 commented 3 years ago

Python 3.9.1+

tvoverbeek commented 3 years ago

See my edited comment above. In /usr/lib/python3/dist-packages/pijuice.py change the 3 occurrences of self.t.isAlive() in _DoTransfer (lines 70-84) to self.t.is_alive(). That should solve it for both pijuice_gui and pijuice_cli.

I will update the source on github accordingly. Thanks for catching this.

ro0TuX777 commented 3 years ago

tvoverbeek, you are AWESOME!! cheers good sir! CHEERS!!

ro0TuX777 commented 3 years ago

Just to follow up on this, I able to launch the gui with the command: sudo -u pijuice python3 /usr/bin/pijuice_gui.py. The application though will not launch from the menu bar. The error message when attempting will be _Failed to execute child process "/usr/bin/pijuicegui" (No such file or directory)

I'm OK with using the command to communicate with the PiJuice hat and closing the ticket. However, for the sake of others who may encounter this issue. wanted to let tvoverbeek and the PiJuice folks know. Thanks again for all the support!

tvoverbeek commented 3 years ago

@ro0TuX777 Are you by any chance running the 64-bit version of Kali? The executables pijuice_gui and pijuice_cli are 32-bit only. They are setuid pijuice and drop all privileges before executing python3 /usr/bin/pijuice_gui.py or python3 /usr/bin/pijuice_cli.py.. In that case you have to rebuild the excutables with the build script in https://github.com/PiSupply/PiJuice/tree/master/Software/Source/Setuid-Wrapper. See also https://github.com/PiSupply/PiJuice/blob/master/Software/OS%20Support/ubuntu_server_64.MD

ro0TuX777 commented 3 years ago

Thanks for the follow up, I am using 32bit. uname -m: armv7l

tvoverbeek commented 3 years ago

When you start /usr/bin/pijuice_gui (or /usr/bin/pijuice_cli) from a terminal window, do you get the same error message?

ro0TuX777 commented 3 years ago

The erro message for both cli and gui show: "No such file or directory"

tvoverbeek commented 3 years ago

I do not know what is going on here. In your post above (https://github.com/PiSupply/PiJuice/issues/648#issuecomment-782710560) the permissions and ownerships are all ok. What is the output of file /usr/bin/pijuice_gui? This is what I get:

/usr/bin/pijuice_gui: setuid ELF 32-bit LSB executable, ARM, EABI5 version 1 (SYSV),

tvoverbeek commented 3 years ago

OK. That is as expected. Next thing to check is if Kali uses the same dynamic loader. What is the output from ls -al /lib/ld* and from ldd /usr/bin/pijuice_gui? Here is my output:

pijuiceoutput

tvoverbeek commented 3 years ago

Here you have your problem. pijuice_gui is looking for /lib/ld-linux-armhf.so.3 which does not exist on your system You can try to add a symbolic link in /lib: sudo ln -s arm-linux-gnueabi/ld-2.31.so ld_linux-armhf.so.3 If that does not work you will have to rebuild the 2 wrappers pijuice_cli and pijuice_gui. See https://github.com/PiSupply/PiJuice/tree/master/Software/Source/Setuid-Wrapper where you find the source and the build script. Resulting programs have to be installed in /usr/bin with setuid pijuice.

ro0TuX777 commented 3 years ago

thanks, attempting to add the symbolic link. Did not work and i'm not familiar with how to rebuild the two wrappers. But will tread carefully with following the instructions.

Further when trying to execute the command:sudo -u pijuice python3 /usr/bin/pijuice_gui.py the new error is:

I opened the first file in reference to see what should be edited in line 20 to correct.

tvoverbeek commented 3 years ago

It looks like something is missing for the python tkinter module. It definitely requires that Tk/Tcl is installed. See also https://docs.python.org/3.7/library/tkinter.html On Raspbian Buster the current version of python3 is 3.7.3 not 3.5

BramWerbrouck commented 4 months ago

Hi,

I have the same problem "failed to execute /usr/bin/pijuice_gui on a fresh installation on Bullseye V11, 32-bit

I read all the comments above, bit none were helping me out. I checked the /usr/lib/python3/dist-packages/pijuice.py file, but I have already the command self.t.is_alive().

Is there something else I can try to get this up and running?

tvoverbeek commented 4 months ago

See issue #1000 (https://github.com/PiSupply/PiJuice/issues/1000#issuecomment-1676377813) for a solution.
