tmux-themepack-jimeh 0+git20190430-1b1b809-1 (ppc64el binary) in ubuntu eoan

 basic theme and powerline themes for tmux.
 .
 The fonts-powerline package is required on your local machine
 in order to render the powerline glyphs properly.
 .
 To enable a theme, you can add a line like the following to your .tmux.conf:
 .
 source-file "/usr/share/tmux/theme-pack-jimeh/powerline/double/cyan.tmuxtheme"
 .
 You can substitute 'cyan' with blue, gray, green, magenta, orange, red or
 yellow.
 .
 You can also substitute 'double' with 'block' to have straight lines on the
 window list.
