From the README:

Quote:Also important: While HPex is currently stable when used with the HP 48 series, I don't currently own any of the Meta Kernel calculators (the 49G, 49g+, 50g, and 48gII). As a result, consider HPex unstable and untested for use with these models.

Software Requirements
Python 3.9 or better

They came only with Python 3.7.
But it appears that they were back-ported to 3.6, so you could install them as a package.

Code:

  File "/home/ramros/hpex/hpex-1.0.0/hpex_gui.py", line 868, in process_kermit_data
    crc=KermitProcessTools.checksum_to_hexstr(i[3])))
  File "/home/ramros/hpex/hpex-1.0.0/helpers.py", line 92, in checksum_to_hexstr
    return '#' + str(hex(int(checksum))).replace('0x', '').upper() + 'h'
ValueError: invalid literal for int() with base 10: '13036,'

From the code in process_kermit_data it looks as if the last element crc contains an additional comma at the end: '13036,'
This leads to the error since it can not be translated to an int.

Code:

        kermit_vars = [row.split() for row in lines]
        
        for i in kermit_vars:
            # each element of each row is the name, size, type, and
            # crc in that order
            
            # undo the thing we did in kermit_done()
            t = i[2]
            if t == 'RealNumber':
                t = 'Real Number'
            elif t == 'GlobalName':
                t = 'Global Name'
                
            self.hpvars.append(
                KermitVariable(name=i[0], size=i[1], vtype=t,
                               crc=KermitProcessTools.checksum_to_hexstr(i[3])))

In order to analyse the problem you could insert a print statement in line 858 of /home/ramros/hpex/hpex-1.0.0/hpex_gui.py:

Code:

            # each element of each row is the name, size, type, and
            # crc in that order
            print(i)

This might give some insights into the output from Kermit.
