I followed the readme for dependency installing, building and installing from the develop branch. Running into two issues trying this... LC_ALL and LANG is not set on my system. develop ~/torbrowser-launcher/dist/deb_dist $ torbrowser-launcher Tor Browser Launcher https://github.com/micahflee/torbrowser-launcher Traceback (most recent call last): File "/usr/bin/torbrowser-launcher", line 352, in <module> app = TorBrowserLauncher(current_tbb_version) File "/usr/bin/torbrowser-launcher", line 13, in __init__ self.discover_arch_lang(); File "/usr/bin/torbrowser-launcher", line 65, in discover_arch_lang self.language = locale.getdefaultlocale()[0].replace('_', '-') AttributeError: 'NoneType' object has no attribute 'replace' Setting them, fixes this. I am not sure how many other people may not have these values set, so I think this should be fixed. Let's set them and try again. develop ~/torbrowser-launcher/dist/deb_dist $ export LC_ALL=en_GB.UTF-8 develop ~/torbrowser-launcher/dist/deb_dist $ export LANG=en_GB.UTF-8 Running into another issue. develop ~/torbrowser-launcher/dist/deb_dist $ torbrowser-launcher Tor Browser Launcher https://github.com/micahflee/torbrowser-launcher Traceback (most recent call last): File "/usr/bin/torbrowser-launcher", line 352, in <module> app = TorBrowserLauncher(current_tbb_version) File "/usr/bin/torbrowser-launcher", line 55, in __init__ self.build_ui() File "/usr/bin/torbrowser-launcher", line 124, in build_ui settings.props.gtk_button_images = True AttributeError: 'gobject.GProps' object has no attribute 'gtk_button_images' develop ~/torbrowser-launcher/dist/deb_dist $ Am I missing a dependency or?
