Hello,

It's not a sudo concern. CPU-G throws the same error at line 1079 in sudo mode. It's due to a switching from amperes to watts for power supply in the latest kernels updates.
I had to slightly modify the two files:

1. /usr/share/cpu-g/src/cpug.py
2. /usr/share/cpu-g/src/investigator.py

to make this application work properly on my Manjaro (18.0.4, Xfce stable, kernel 4.19.66-1) box with french locale (and displaying now Xorg version, accurate distro logo, battery charges: now, full, full design and power now with the good units).

Take a look at the two files in the attached tar.gz part and compare them with the original files of the 25478f0 commit with Diffuse Merge Tool for example.

Link to attachment: cpu-g-src.tar.gz

In your system the original files should be in:
/opt/extras.ubuntu.com/cpu-g/share/cpu-g

Edit: answer modified for more clarity

Hi, I replaced the original cpug.py and investigator.py with your code, it still crashed:

Environment Ubuntu 18.04 bonic

[Armag67]

There is a subtle bug in the sysdevcpu function in investigator.py. This bug only occur if /proc/cpuinfo and /sys/devices/system/cpu/ don't return the same number of cores. Then sysdevcpu function try to print:

            print("Error: Cannot decide if the cores are %s or %s.\n" +
                  "Using the lowest value as the real cores number." %
                  (self.cpuinfo('coresnum'), coresinsysdev))

which is buggy.
Try to replace these three lines by:

            print("Error: Cannot decide if the cores are %s or %s.\n"
                  % (self.cpuinfo('coresnum'), coresinsysdev) +
                  "Using the lowest value as the real cores number.")

But do not forget to respect the indentations, especially the 12 spaces at the beginning of the first line.

Edited January, 9 for more clarity.

I was able to reproduce the error in @BriFuture's comment on Ubuntu 18.04 by installing CPU-G from the PPA then running it in the terminal without sudo, even before applying @Armag67 's first fix.

Applying the first fix only shifts the line number for me.

Applying both the first fix and the second fix finally solves the problem -- now it runs but gives an interesting terminal output, both without and with sudo.

[Errno 2] No translation file found for domain: 'cpu-g'

Here's an interesting bit: when I only applied the second fix (but not the first), I can run it without sudo, but running under sudo crashes with a different error message:

[Errno 2] No translation file found for domain: 'cpu-g'
Traceback (most recent call last):

  File "/usr/lib/python3.6/re.py", line 182, in search
    return _compile(pattern, flags).search(string)
TypeError: cannot use a string pattern on a bytes-like object

Finally, to remove the interesting output, commit 073e93. For other PPA users out there: change line 269 in /opt/extras.ubuntu.com/cpu-g/share/cpu-g/investigator.py (line 280 after the first fix) from

        coresinsysdev = str(
            len(re.findall("'cpu[0-9]'",
                           str(os.listdir("/sys/devices/system/cpu/")))))

to

        coresinsysdev = str(
            len(re.findall("'cpu[0-9]+'",
                           str(os.listdir("/sys/devices/system/cpu/")))))
