There's a SyntaxWarning since Python 3.12 using peda.py at GDB startup. This was introduced here when the DeprecationWarning was upgraded to SyntaxWarning.

/usr/share/peda/peda.py:151: SyntaxWarning: invalid escape sequence '['
p = re.compile("(.)[(.)]") # DWORD PTR [esi+eax1]
/usr/share/peda/peda.py:373: SyntaxWarning: invalid escape sequence '\s'
p = re.compile(".exec file:\s`(.)'")
/usr/share/peda/peda.py:550: SyntaxWarning: invalid escape sequence '\d'
p = re.compile("^(\d*)\s*(.breakpoint)\s(keep|del)\s*(y|n)\s*(0x[^ ])\s(.*)")
[...]

It should be fixed by using raw string literals (r"...").

can confirm the invalid sequence warnings.
regarding the error for module six I recommend force reinstalling the peda package from pacman

1.for SyntaxWarning

you can fix this by adding r to the strings
eg

 p = re.compile(r"(.*)\[(.*)\]") # DWORD PTR [esi+eax*1]

to make it raw string, pull request #178 fixes this.

2.for six.moves not found

you can use

pip install six

or if using arch, install from the repos

sudo pacman -S python-six

and remove the six.py in the lib
so it uses the global ones and not the local one found in lib
