Residual Configuration After McFly Update May Cause Errors

In our recent update to McFly, we deprecated a default setting to override the Ctrl-R with McFly by removing /etc/profile.d/mcfly.bash from the package. However, as this file was registered as a configuration file (conffile), it will not be removed automatically. With this residual configuration, you may encounter the following error while starting a shell session:

error: a value is required for '--append-to-histfile <HISTFILE>' but none was supplied

For more information, try '--help'.

You may resolve this issue by removing the residual file with the following command:

sudo rm -v /etc/profile.d/mcfly.bash

After which, restart your shell or terminal, and the above error should no longer occur.
