sh: 1: Syntax error: "}" unexpected when I do a sudo apt install

[MoezLog]

After installing the Ubuntu 24.04 script, I receive this error everytime I do a sudo apt install any tool:

sh: 1: Syntax error: "}" unexpected E: Problem executing scripts DPkg::Post-Invoke 'if [ -d /var/lib/update-notifier ]; then touch /var/lib/update-notifier/dpkg-run-stamp; fi; };' E: Sub-process returned an error code

According to chatGPT, the problem should be here in this file /etc/apt/apt.conf.d/99update-notifier:
DPkg::Post-Invoke {"if [ -d /var/lib/update-notifier ]; then touch /var/lib/update-notifier/dpkg-run-stamp; fi; };";

As a correction, I replaced the content of /etc/apt/apt.conf.d/99update-notifier as follow:
DPkg::Post-Invoke { "if [ -d /var/lib/update-notifier ]; then touch /var/lib/update-notifier/dpkg-run-stamp; fi"; };

Fixed in commit bbcb332. The APT configuration syntax in /etc/apt/apt.conf.d/99update-notifier has been corrected to use proper DPkg::Post-Invoke syntax.
