 Hi everyone,

 I installed GRASS 7.8.1 via the ubuntugis-unstable repository on my
 machine running Pop! OS 18.04 (based on Ubuntu 18.04). When I run GRASS,
 this error occurs:
 {{{

 ERROR: Error in GUI startup. See messages above (if any) and if necessary,
 please report this error to the GRASS developers.
 On systems with package manager, make sure you have the right GUI package,
 probably named grass-gui, installed.
 To run GRASS GIS in text mode use the --text flag.
 Use '--help' for further options
      grass78 --help

 I checked the module in question (wx). The said module isn't available on
 the default Python (python2) of my machine.
 {{{
 Python 2.7.15+ (default, Oct  7 2019, 17:39:04)
 [GCC 7.4.0] on linux2
 Type "help", "copyright", "credits" or "license" for more information.
 >>> import wx
 Traceback (most recent call last):
   File "<stdin>", line 1, in <module>
 ImportError: No module named wx
 >>>
 }}}

 It is however available on my machine's Python 3.
 {{{
 Python 3.6.8 (default, Oct  7 2019, 12:59:55)
 [GCC 8.3.0] on linux
 Type "help", "copyright", "credits" or "license" for more information.
 >>> import wx
 >>> wx.__version__
 '4.0.1'
 >>>
 }}}

 When I try to import NewIdRef, it doesn't exist but NewId does.
 {{{
 Python 3.6.8 (default, Oct  7 2019, 12:59:55)
 [GCC 8.3.0] on linux
 Type "help", "copyright", "credits" or "license" for more information.
 >>> import wx
 >>> from wx import NewIdRef
 Traceback (most recent call last):
   File "<stdin>", line 1, in <module>
 ImportError: cannot import name 'NewIdRef'
 >>> from wx import NewId
 >>>
 }}}

 Finally, GRASS text mode works. It really is just the GUI that fails.

 Thanks everyone!
