LocalSend for quick local network file sharing from my phone that just werks. I prefer it over kde connect because the latter uses lots of random ports that kinda bloat my firewall whitelist. I know there is an alternative called warpinator, but I don't see a reason to change my preferences for now.

Darktable. A replacement for adobe lightroom.

Qalculate

I'm going to try to mention things I haven't seen already written, though I may repeat some of the more important ones to me.

(In no particular order)

Terminal:

• Kitty (Main Terminal)
• Fish (Terminal Prompt)
• Neovim (Code/Text editing)
• Zoxide (a directory changer; once you go to a directory, you can type z and a partial name to go back to it)
• Atuin (a command history lister, can get a key and bring over commands from other systems)
• Midnight Commander (CLI file manager)
• Btop (CLI system monitor)
• Palette (I do a lot of theming in different configs as well as HTML/CSS, so its nice to have something to quick convert hex to RGB).

GUI:

• Timeshift (backup/restore)
• Eddie (for AirVPN)
• novelWriter (my FAVORITE writing tool for my books)
• Floorp (Firefox fork browser)
• Conky Manager 2 (desktop monitoring widgets)
• Rofi (keyboard launcher)
• firewalld (tried this out recently, good firewall)
• Flameshot (ALWAYS; its my favorite screenshot tool)
• MPV (I still get VLC, but opt for MPV most of the time for videos/streaming)
• Speedcrunch (A+ calculator)
• Steam
• Lutris
• Protonup-QT (to inject GE Proton into Steam/Lutris)
• Stremio (a great little streaming tool)

I would like to add that I do use Arch, but I'm fairly sure 99% of these packages, if not all of them, are available for most other distros.

For CLI lovers: Check out Terminal Trove

Edit: I did see that someone mentioned no explanations on the apps, so I tried to put a little blurb on each.

If you use the terminal and have a tendency to fat finger commands, I would recommend "The Fuck".

It always makes me smile to type fuck into the terminal. 🙂

There's a lot of letters here, but nobody is explaining what they mean. How do I know what I need? I'm not gonna install everything, or look up every single program to see.

• GIMP (with photogimp patch)
• Steam
• Librewolf (I could also opt for a chromium based browser)
• Tor Browser (to browse onion links/throwaway browser)
• Heroic Games Launcher
• Prism Launcher
• latest Java lts (either from adoptium or openjdk i dont care about flashy new features)
• Libreoffice Still (similar to the second reason above and onlyoffice in appimage due to Libreoffice weird handling with ppsx files and powerpoints)
• QEMU/KVM with virt manager
• Gnome evolution (if it's gtk desktop I could opt for other email clients)
• Proton-GE
• WINE
• Ghostty(Kinda sucks it's based on libadwaita and gnome forces this theme on you no matter your desktop)
• Fish/ZSH(fish not having posix compatibility is kinda annoying)
• MPV (I could still use vlc but I prefer mpv because it can stream youtube links)
• ytp-dl(I can opt for a gui for convenience sake)
• BTOP
• Fastfetch

I'm a former Windows user, so I install activate-linux for similar experience.

System :

• zram (who says you can't just install more RAM 😄 )

Terminal :

• kitty (terminal emulator)
• fastfetch (must take screenshots to show off every new Linux install, it's in the EULA)
• zsh (thought I'd like to try nushell one of these days) with zsh-syntax-highlighting, zsh-completiions and zsh-suggestions
• GNU Stow (to manage symlinks, I store my dotfiles in a repo witch contains home, etc and usr folders, and I use GNU Stow to symlink them respectively to /home/username, /etc and /usr, that way all my config is in the same place so I can back it up easily and have version control)
• rsync (to sync backup folders)
• btop (system monitoring)
• clamav (antivirus)
• brightnessctl (for screen brightness control, but I should probably use brillo instead https://www.youtube.com/watch?v=pGOaSS8nEQA)
• yt-dpl (for downloading videos from YouTube/TikTok/wherever else)
• ani-cli (for watching anime from the terminal, obviously a must-have for any ~~Arch~~ Mint user)
• figlet (to write text from fonts made of ASCII art)
• cpipes, asciiquarium, cbonsai, matrix for when I get bored in meetings
• hollywood and rust-stakeholer if I ever need to pretend I'm doing something productive
• lots of TUI apps from https://github.com/rothgar/awesome-tuis

General GUI apps :

• Sway (tiling WM) though I'd really like to try niri (instead of several workspace it has a single one of infinite length that you can scroll through)
• rofi and rofi-calc (app launcher that can also do a lot other stuff if you want like file browser, ssh menu, calculator, emoji selector, it's very light and superfast), also rofi-emoji (emoji selector)
• VSCode (code editor)
• KeepassXC (password manager)
• lutris, steam, protontricks, ProtonGE (gaming)
• FontManager
• Ventoy (for making USBs with multiple ISO on them)
• LibreOffice

Internet :

• Waterfox + LibreWolf (web browsers) with the following extensions : uBlock, Consent-O-matic, DownThemAll, KeepasXC-Browser, Copy PlainText, Copy Link Text, EPUB Reader, Markdown Viewer Web Ext, Sponsor Block, Return YouTube Dislike, YouTube Anti Translate, CanvasBlocker, Font Fingerprint Defender, WebGL Fingerprint Defender (I had to give up on User-Agent Switcher because it causes me to be blocked on too many websites)
• qBittorrent (BitTorrent client)
• FileZilla (FTP client)

Media :

• XVview (image viewer)
• ksnip (GUI screen capture)
• Gimp (image editor)
• Inkscape (vector image editor)
• MPC and VLC (audio/video players)
• Libation (to liberate Audible audiobooks from your account)
• cheese (camera)

I'm on Arch so the package names might be a bit different

• Kate
• Yakuake
• Brave, Vivaldi, Chromium
• LibreOffice (I use Calc a lot)
• Kate
• Ocular
• DoH-client
• htop
• ncdu
• Windscribe
• virt-manager

... and more I can't remember right now, because it's too early in the morning.

EDIT:

• nano
• mc (midnight commander)

neovim, basic development utilities (gcc, make...), zsh, ssh, btop, nvtop, kitty, river, git, cargo, nix, flatpak, ytdlp, ffmpeg, firefox, chromium, python

• Shell: Fish
• Resource monitoring: Btop
• Browser: Librewolf
• Text editor: Vim (unless you do heavy programming then neovim)
• Basic tools: git and wget
• Themeing: GTK customizer
• Terminal: Foot

• Anki
• Beyond Compare
• Discord
• GIMP (Not sure if it's installed by default on Linux Mint) with PhotoGIMP patch.
• GnuCash
• GParted
• KeePassXC
• KWrite + Kate
• Pinta
• qbittorrent
• Steam
• Telegram
• Thunderbird
• virt-manager
• VLC
• Wine

guix and/or nix

Both are functional package managers and manage dependency trees better than flatpak IMO (also the package description languages mean you can manipulate the package definitions at install time much easier)

If you can't find a package in guix/nix then it behooves you to use flatpak

Fortune. Cowsay.

kitty, nvim, fish, zed, mpv, btop, borg. Weird how all the gone ones have short names. Depending on the system, I would add tlp as well.

Whatever you need to be productive.

For me personally I install kitty terminal and integrate it with fish asap. Then I waste a bunch of time customizing it to my liking. My preferred text editor is Kate regardless of what DE I'm using and I usually get bleachbit for basic cleanup.

Probably would run into these things needed in this order:

• The text editor kakoune
• Add uBlock Origin to Firefox
• KeepassXC
• tmux

Then nodejs if it's a laptop, or Steam if it's a desktop.

mpv
pdftk
yt-dlp

Helpful answer: vlc, libreoffice, gimp, inkscape, zathura, obs-studio

Real answer: gnome, run-or-raise, foot, fish, tmux, fzf, silver-searcher, neovim, neomutt, vifm

People replying - how about telling us why you consider your answer a must-install tool?

sl and KDE plasma

Potentially unpopular opinion: a bunch of rust replacements for the common terminal utilities: eza, bat, dust, fd, helix. Also fish and nushell, yt-dlp, and some of my favorite programming languages.

vim, htop , iotop, screen, nslookup.

Timeshift is number 1

Also it's recommended to not reinstall a bunch of stuff and just install the app when you needed it that's the power of Linux. Unless you just want to learn the software then disregard

I believe Firefox is installed by default on Mint, so install uBO.

Transmission.

Veracrypt.

Audacious.

Zram

CopyQ is an advanced clipboard manager. Gimp is great but Pinta is easy for quick, minor image adjustments. System Monitor is an applet that displays system information by double clicking on a taskbar icon. If you use VPNs, the IP Indicator applet shows the country of your public IP or customized icon when matching ISP is found.
