/etc/bash.bashrc.backup-before-nix contains NIX information

[VanessaPC]

Describe the bug

According to the instructions I am getting on failure I get:

2. Ensure /etc/bashrc.backup-before-nix does not have anything Nix-related in it. If it does, something is probably quite wrong. Please open an issue or get in touch immediately.

However,the files contains this lines

# Nix
if [ -e '/nix/var/nix/profiles/default/etc/profile.d/nix-daemon.sh' ]; then
  . '/nix/var/nix/profiles/default/etc/profile.d/nix-daemon.sh'
fi
# End Nix

Steps To Reproduce

1. Go to '...'
2. Click on '....'
3. Scroll down to '....'
4. See error

Expected behavior

A clear and concise description of what you expected to happen.

nix-env --version output

It's a sign nix was installed before the backups were taken, so you may need to clean it up manually.

I'd try:

1. Run grep "End Nix" /etc/* and manually remove those lines from any matching files that don't have the backup-before-nix extension.
2. Remove all of the files with the backup-before-nix extension.
3. Follow the remaining appropriate macOS/Linux uninstall instructions before reinstalling it: https://nixos.org/manual/nix/stable/installation/installing-binary.html#uninstalling

Thank you.

I did that, as well as uninstalling from mac, it then worked.
