I have successfully installed and used Clockworkmod USB tethering for several years with Ubuntu 16.04. After an upgrade to 18.04 I followed the same procedure as previously used with 16.04 (see youtube video with instructions in the description), but with 18.04 the installation stops when I reach the "configure" stage.
Specifically,
in Terminal and in the "node" folder (or directory) simply type:
./configure
this produces:
File "./configure", line 463, in
configure_node(output)
File "./configure", line 370, in configure_node
o['variables']['gcc_version'] = 10 * cc_version[0] + cc_version[1]
IndexError: tuple index out of range
Has anyone successfully gotten around this problem?
