title: My Kubuntu Setup Notes

This is an assorted bunch of notes I made while setting up a new laptop with kubuntu (well sold 'for parts' on eBay and nursed back to health, previously having hat Rocky but after the RHEL debacle I'm done with RH stuff...) I thought to
write down *everything* I did during installation. Some of these things depend on personal files I have access
to, but in any case it is an illustration of what I'll do to configure a system for 'fun' (that is, low security).

**Health warning:** some of these settings are for convenience, and on machines where security is not a major concern. A spare laptop running Linux for fun and educational value needn't have the same degree of security
as a machine on which things like sensitive financial documents are stored.

**Note for general readers** Some of my notes and stuff are on private pages or github repos. What is here is stuff I'm happy to share.

# Install
```
# as root

# make sudo easier -- don't do this where security matters
echo ALL ALL = NOPASSWD: ALL > /etc/sudoers.d/wideopen

# disable and stop unattended-upgrades as it can interfere with apt-get
systemctl disable unattended-upgrades
systemctl stop unattended-upgrades
```

# System Monitoring
There are a few utilities that improve on top (source: [itsfoss](https://itsfoss.com/linux-system-monitoring-tools/)).
1. htop
2. atop
3. nmon
4. vtop
5. bashtop
6. gtop
7. glances

# Install Chrome
Chrome
```bash
wget https://dl.google.com/linux/direct/google-chrome-stable_current_amd64.deb && \
sudo dpkg -i google-chrome-stable_current_amd64.deb
```
Log in, get tampermonkey scripts.

# Nvm
Get nvm from `https://github.com/nvm-sh/nvm`: install via
```
curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.39.3/install.sh | bash
```
Add path to point to current nvm version (else we have to run nvm before we can run node and npm)

# Tmux
Get `.tmux.conf`: currently
```
setw -g mode-keys vi
bind-key -n C-Left previous-window
bind-key -n C-Right next-window
bind-key -n C-S-Left switch-client -p
bind-key -n C-S-Right switch-client -n
bind-key -n C-M-Left select-pane -L
bind-key -n C-M-Right select-pane -R
bind-key -n C-M-Up select-pane -U
bind-key -n C-M-Down select-pane -D
```
# 
Get mdview from `https://github.com/mapitman/mdview/`
```
curl -L -O https://github.com/mapitman/mdview/releases/download/1.5.0/mdview_1.5.0_amd64.deb && \
sudo dpkg --install mdview_1.5.0_amd64.deb
```

# Mpd
Put music in `/data/music`. Copy `.mpd/conf` from music-server. Create `.mpd/playlists`.

# Settings
Copy in ssh config and `mygit`. Get hosts from allsup.co.
In `mygit/myvim` run `install.sh`
Get nvim config from version control.

## Nvim
For the IDE like setup, use a separate nvim app.
Clone config from `my_nvim2`

# My stuff
Make `/usr/jda`, git clone `cmds`, then `install.sh`.
Edit `/etc/sudoers` to add `/usr/jda/bin` to the path.

# Rust
See Rust_Setup

# KDE Setup
See KDE_Plasma

# Python
See Python_Setup

# Samba
See Samba_Setup

# Dircolors
Change other writable to make it readable text (I make it red on black)
```
OTHER_WRITABLE 1;4;31;40 # dir that is other-writable (o+w) and not sticky
```
Use `dircolors -p` to print database to a file, then edit, then
```
eval "$(dircolors <filename>)"
```
If this is dumped in `~/.dircolors` then `dircolors.stuff` will take
care of this.

# Fonts
Adobe fonts. Nerd fonts.

# SSH
Enable `user_allow_other` in `/etc/fuse.conf` so that `sshfs` doesn't restrict to one user.
This is useful when e.g. running an installer with `sudo` where the file is on a remote system
mounted by a user via `sshfs`.

## Profiles
Create mydef with Linux Colors and Hack Nerdfont

# vim
get mygit and my_nvim2 from git repo

# apache2
```
a2enmod rewrite
```
Ensure php takes priority over html: edit `mods-enabled/dir.conf`
```
        DirectoryIndex index.php index.html index.cgi index.pl index.xhtml index.htm
```

# XCompose
Enable compose key in systemsettings (input devices→keyboard→advanced and it's near the bottom,
I use right alt). Then if desired create `~/.XCompose` if you want to add to the defaults.
[Mine is here](XCompose). 

# 22.04 Fix Zip
There is a bug in the zip that is shipped. 
To see if you have the bug, create a file named `ö` (not the umlaut: I use
compose key to type this) and try to zip it:
```
touch ö
zip -9r o.zip ö
```
with stock 22.04 this results in
```
*** buffer overflow detected ***: terminated


zip error: Interrupted (aborting)
```

It does not happen if we `apt source` and build from source.
Thus edit `/etc/apt/sources.list/ubuntu. Change the 
```
Types: deb

```
to
```
Types: deb deb-src
```
then
```
mkdir -p ~/src # or some other place where you build stuff
cd ~/src
apt-get source zip
sudo apt-get build-dep -y zip
cd zip.3.0
make -f unix/Makefile generic_gcc
sudo cp -t /usr/bin zip zipcloak zipnote zipsplit
