You have entries for different debian releases but no entry for the one you actually installed (bookworm). Change this to

    
deb https://deb.debian.org/debian/ bookworm main contrib non-free-firmware non-free
deb https://deb.debian.org/debian/ bookworm-updates main contrib non-free-firmware non-free
deb https://security.debian.org/debian-security bookworm-security main contrib non-free-firmware non-free

  

Then run apt update and apt dist-upgrade to update all packages that you installed from older repos. Then apt autoremove to remove packages that are not longer needed.

After that you may still have to downgrade packages installed from trixie repos or remove them if they are not in bookworm. To do this, edit your /etc/apt/preferences file (create it if it does not exist) and add

    
Package: *
Pin: release n=bookworm
Pin-Priority: 1001

Package: *
Pin: origin ""
Pin-Priority: -10

  

Then run apt dist-upgrade and apt autoremove again. When all packages are downgraded, remove these lines from /etc/apt/preferences.

For more details, refer to the documentation:

• https://wiki.debian.org/SourcesList
• https://wiki.debian.org/AptConfiguration

It's hard to guess what is wrong with your configuration. Show your sources.list.

To disable translation for commands you run in terminal, do export LANG=C.

When using "<<-", shell removes all tabs from the beginning of each line. So you have to use tabs for formatting inside your script and then spaces for HTML formatting, as in my example. Or use "<<" without dash to preserve tabs.

cat does not create file, your shell does when you redirect the standard output with > file.

You need cat because it reads stdin and prints it to stdout. echo does not read stdin, it prints its arguments.

Multiply before you divide to keep precision: 1000 * $i1p / $apiresponse

And again, using here-document greatly improves readability, like this.

Again, you don't need sed for this, simply set scale=2 or how many digits after decimal point you need. Also you missed ! in the shebang (#!/bin/bash or #!/bin/sh).

Your mistake is that after variable substitution bash does not handle quoted strings, i.e. it does not remove single quotes from sed command line. If you really need this to happen, you have to use eval:

i1xmr=$(echo "$i1p/$apiresponse*1000" | bc -l | eval $rmdec)

However using functions is a better solution in general. But in this particular case, I guess, you only need to change the bc's scale instead of using sed:

i1xmr=$(echo "scale=17; $i1p/$apiresponse*1000" | bc -l)

For better readability you may use heredoc instead of echo:

    ~~~
i1xmr=$( bc -l << EOF
scale=17
$i1p/$apiresponse*1000
EOF
)
~~~
  

But you don't need to cd before running ls. And in most cases you don't even need ls, autocompletion is enough.

I used mc many yeas ago until I learned CLI utils well enough to use them efficiently. I think, it is the main point: you get a tool that does not require a lot of time to start using it. But in most usage scenarios TUI FMs are less effective than CLI.

--purge does not do anything with dependencies. You will need to explicitly remove all packages that are marked as installed manually, i. e. all packages that you pointed a package manager to install. If a DE was installed automatically by Debian installer, or if you installed it with apt install xfce4, the only manually installed component it the xfce4 metapackage, and using the --auto-remove flag will remove all its dependencies. But if you additionally installed any components or packages that depend on that components, you will also need to clean them up manually.

Non-ASCII characters can cause troubles because of different encodings and because you may need to type them on a machine where corresponding keyboard layout is missing.

The password length limit is nothing short of stupid.

apt remove --auto-remove xfce4

Bad practice is not using sudo (I do use it), but assuming that everyone has sudo installed and configured the same way as you have.

Additionally, which distro doesn’t have sudo? I’m sure there are some but by far the majority of distos have and use sudo.

Almost all distros have sudo. But many of them don't install it by default. Most popular distros except Ubuntu (I mean Debian, Fedora and RHEL clones) provide a choice to user at install time: set the root password or install sudo and enable it for the admin user. In OpenSUSE sudo is installed by default, however it is configured in slightly different way than usually. Etc., etc.

You are doing something wrong. I stopped distrohopping ~13 years ago and never had to reinstall OS after that. If I get error messages, they are helpful enough to figure out the root of the problem (unlike that in Windows, where everything under the hood is hidden from user). For me Windows and macOS are frustrating, not Linux.

Maybe Linux is not good enough for you, maybe you are not good enough for Linux. Anyway, don't constrain yourself, use software that you are comfortable with.

Yes.

Fedora is the new Ubuntu

Fedora is older than Ubuntu.

Just because almost nobody need to have an iso library.

Any chances you will use them?

"Using regular expressions" is misleading. A beginner could think that by default grep is looking for a literal string, but it does not.
