Choose a Linux package manager GUI by matching it to your distribution, the software sources you use and the job you need done. Synaptic handles APT packages; Shelly targets Arch-based systems; and bauh lists support for several formats, with setup requirements that vary by backend. There is no universal winner among them.
What a package manager GUI actually handles
An app catalog and a package-level manager can do different jobs. A catalog helps you browse and install apps from the sources it connects to. A package-level tool can also search installed packages, remove them or manage repository settings. Support for one format does not automatically mean a tool manages every other install or update route on your system.
APT, the package-management system used by Debian and Ubuntu, is the focus of Synaptic. Flatpak is an application format; AUR means Arch User Repository, a community package source for Arch systems.
Match the GUI to your distribution and sources
The table separates project-documented capabilities from desktop-store descriptions in Jack Wallen’s roundup. The roundup identifies COSMIC Store with Pop!_OS running COSMIC Desktop, KDE Discover with KDE Plasma, Bazaar as Flatpak-only, and Linux Mint Software Manager with Linux Mint.
| GUI | Distribution or context | Documented scope | Important qualification |
| Synaptic | Debian and Ubuntu package management | APT package search, installation, removal, upgrades and downgrades; repository management and version locking | A GTK front end for APT; it does not manage Snaps |
| Shelly | Arch Linux and Arch-based distributions | Native package operations, AUR and AppImage; Flatpak through an optional backend | Flatpak requires both flatpak and shelly-flatpak-backend |
| bauh | Ubuntu-based and Arch-based distributions | AppImage, Debian and Arch packages including AUR, Flatpak, Snap and web applications | Some backends need optional dependencies; AppImage discovery is limited to x86_64 files, and Arch repository packages lack downgrade and history actions |
| COSMIC Store | Pop!_OS running COSMIC Desktop | The roundup describes update integration and Flatpak sources such as Flathub, COSMIC repositories and custom sources | The described context is Pop!_OS with COSMIC Desktop |
| KDE Discover | KDE Plasma | The roundup describes distribution repositories, add-ons, upgrades and font installation; Flatpak or Snap support can be added | Available backends depend on setup |
| Bazaar | Linux systems using Flatpak | The roundup describes installing, removing and updating Flatpak apps | Flatpak-focused, not a manager for native distribution packages |
| Linux Mint Software Manager | Linux Mint | The roundup describes categorized app discovery and package-source tasks | Searching package descriptions can slow searches, according to the roundup |
For detailed APT operations on Debian or Ubuntu, Synaptic is the direct fit: its project lists package search, installation, removal, upgrades, downgrades, repository management and version locking. That package-level scope is useful when an app-store view does not show a package you installed another way.
For Arch-based systems, Shelly is designed around native Arch package operations. It also supports AUR and AppImage workflows. If you want Flatpak in the same interface, plan on installing the separate backend as well; it is not part of Shelly’s base package.
If your system uses several package formats, bauh lists the broadest mix here: AppImage, Debian packages, Arch packages including AUR, Flatpak, Snap and web applications. Check the dependencies for the formats you need. Its project also specifies that AppImage discovery covers x86_64 files, while Arch repository packages do not support downgrade or history actions.
Shelly’s Flatpak support takes extra setup
Shelly’s project instructions require both flatpak and shelly-flatpak-backend for its optional Flatpak support. Its native Arch package operations do not depend on those additions, so the extra setup matters specifically if you want to manage Flatpaks through Shelly.
A manually installed .deb on Ubuntu
If Ubuntu App Center does not list a downloaded .deb package installed outside the store, participants in an Ubuntu support discussion recommend using Synaptic to find the installed package and remove it. They also say App Center may not handle updates for that package. If the software does not update itself, you may need to get a newer package from its vendor.
Removing a package and receiving its updates are separate tasks. Synaptic can help with package-level lookup and removal, while the vendor may remain the update route in this described Ubuntu situation. Synaptic does not manage Snaps, so it does not replace App Center for that format.
