Ubuntu 18.04 Theme not displayed correctly

[sn1c3]

I installed the theme as recommended and now my tmux terminal looks like this:

Here is my .tmux.conf:

# remap prefix from 'C-b' to 'C-a'
unbind C-b
set-option -g prefix C-a
bind-key C-a send-prefix

# split panes using h and v
bind -n M-h split-window -h
bind -n M-v split-window -v
#unbind '"'
#unbind %

# switch panes using Alt-arrow without prefix
bind -n M-Left select-pane -L
bind -n M-Right select-pane -R
bind -n M-Up select-pane -U
bind -n M-Down select-pane -D

# Enable mouse control (clickable windows, panes, resizable panes)
set -g mouse on

# Reload tmux.conf with r
bind-key r source-file ~/.tmux.conf \; display-message "~/.tmux.conf reloaded"

# color stuff
#xterm-256color
set -as terminal-overrides ",xterm-256color*:Tc"

# List of plugins
set -g @plugin 'tmux-plugins/tpm'
set -g @plugin 'tmux-plugins/tmux-sensible'

# Other examples:
# set -g @plugin 'github_username/plugin_name'
# set -g @plugin 'github_username/plugin_name#branch'
# set -g @plugin 'git@github.com:user/plugin'
# set -g @plugin 'git@bitbucket.com:user/plugin'
set -g @plugin "arcticicestudio/nord-tmux"

# Initialize TMUX plugin manager (keep this line at the very bottom of tmux.conf)
run '~/.tmux/plugins/tpm/tpm'

Are there any settings I am missing?

Hi @sn1c3 :wave:

Based on your screenshot it looks like there are two different problems:

1. The actual Nord colors are not available because the theme is not installed for your terminal. A wild guess is that you're using “GNOME Terminal“ so you need to install the appropriate theme which would be “Nord GNOME Terminal“ in this case. Please make sure to read and follow the official Nord tmux installation documentation, especially the information box at the top of the page that states that

   tmux must be used with a Nord terminal emulator theme in order to work properly! [...]

2. The invalid glyphs in the status bar content are most likely caused by an incompatible font family used by your terminal. The Nord tmux configuration documentation has a section about font rendering. It contains information about the requirement to install a “patched“ font in order to render special characters like the ones used by the default status bar content.
