I'm seeing the bug in the linked GitHub issue on Fedora Silverblue 39 with the powerline and powerline-fonts package added. An example, that turns up upon every shell start: ``` /usr/lib/python3.12/site-packages/powerline/bindings/config.py:179: SyntaxWarning: invalid escape sequence '\$' TMUX_VAR_RE = re.compile('\$(_POWERLINE_\w+)') /usr/lib/python3.12/site-packages/powerline/bindings/config.py:179: SyntaxWarning: invalid escape sequence '\$' TMUX_VAR_RE = re.compile('\$(_POWERLINE_\w+)') /usr/lib/python3.12/site-packages/powerline/bindings/config.py:179: SyntaxWarning: invalid escape sequence '\$' TMUX_VAR_RE = re.compile('\$(_POWERLINE_\w+)') user@framework:~$ ``` There doesn't seem to have been an upstream tagged release of Powerline for a while, but there is a one line fix available which might be easy enough to cherry-pick the commit from and pull into the Fedora package: https://github.com/powerline/powerline/pull/2245/files Reproducible: Always Steps to Reproduce: 1. Install Fedora Silverblue 39 2. Install the powerline and powerline-fonts packages 3. Add the Powerline start script to .bashrc or to /etc/profile.d as described in: https://fedoramagazine.org/add-power-terminal-powerline/ 4. Open a terminal and observe the error above Actual Results: The error above, reproducible by others as described in the GitHub issue (not my own) and fixed upstream already. Expected Results: No Python errors when opening a new terminal.
