How to uninstall everything this "script" did?

[Delicious-Bacon]

I am working on Rocky Linux 9 and I realized too late that this was made for Ubuntu...

I was following this video: Lesson 2: Practical Deep Learning for Coders 2022, which "guided" me to install everything with fastsetup and continue to install fastchan fastai nbdev jupyter with mamba.

1. How do I boot into desktop without doing conda config --set auto_activate_base False?

First of all, after doing everything and rebooting my PC, I could not launch my kernel’s desktop with the command startx anymore. I spent an hour looking around for a “solution” and it ended up being mamba’s base environment being activated by default. I deactivated it to be able to enter my desktop.

2. Why is this failing?

Since it’s not recommended to install any packages into base env as the video tutorial suggests, but instead create new envs, I wanted to uninstall the fastchan fastai, fastchan nbdev and fastchan jupyter from the base env, but I am unable to uninstall fastchan jupyter because it keeps tossing errors.

An unexpected error has occurred. Conda has prepared the above report.

3. Start anew from fresh install?

My guess is that I would do best to do a fresh install of mamba, but how to do that? I tried to uninstall it via conda uninstall mamba but conda then wants to download each package mamba had instead...

4. Another issue

I also have missing .bashrc.local warnings whenever I open terminal now, so there's something messed up with that too. My .bashrc looks like this:

# .bashrc

# Source global definitions
if [ -f /etc/bashrc ]; then
	. /etc/bashrc
fi

# User specific environment
if ! [[ "$PATH" =~ "$HOME/.local/bin:$HOME/bin:" ]]
then
    PATH="$HOME/.local/bin:$HOME/bin:$PATH"
fi
export PATH

# Uncomment the following line if you don't like systemctl's auto-paging feature:
# export SYSTEMD_PAGER=

# User specific aliases and functions
if [ -d ~/.bashrc.d ]; then
	for rc in ~/.bashrc.d/*; do
		if [ -f "$rc" ]; then
			. "$rc"
		fi
	done
fi

unset rc

# >>> conda initialize >>>
# !! Contents within this block are managed by 'conda init' !!
__conda_setup="$('/home/sebastijan/mambaforge/bin/conda' 'shell.bash' 'hook' 2> /dev/null)"
if [ $? -eq 0 ]; then
    eval "$__conda_setup"
else
    if [ -f "/home/sebastijan/mambaforge/etc/profile.d/conda.sh" ]; then
        . "/home/sebastijan/mambaforge/etc/profile.d/conda.sh"
    else
        export PATH="/home/sebastijan/mambaforge/bin:$PATH"
    fi
fi
unset __conda_setup

if [ -f "/home/sebastijan/mambaforge/etc/profile.d/mamba.sh" ]; then
    . "/home/sebastijan/mambaforge/etc/profile.d/mamba.sh"
fi
