There are currently three Minimal TemplateVMs corresponding to the standard [Fedora](/doc/templates/fedora/), [Debian](/doc/templates/debian/), [CentOS](/doc/templates/centos/) and [Gentoo](/doc/templates/gentoo/) TemplateVMs.
2. If something works with a standard TemplateVM but not the minimal version, this is most likely due to user error (e.g., a missing package or misconfiguration) rather than a bug.
If you want to be able to use `sudo` inside a Minimal TemplateVM (or TemplateBasedVMs based on a Minimal TemplateVM), open a root terminal as just instructed, then install the `qubes-core-agent-passwordless-root` package.
Optionally, verify that passwordless root now works by opening a normal (non-root) xterm window in the Minimal TemplateVM, then issue the command `sudo -l`.
This should give you output that includes the `NOPASSWD` keyword.
## Customization
You may wish to clone the original template and make any changes in the clone instead of the original template.
You must start the clone in order to customize it.
Customizing the template for specific use cases normally only requires installing additional packages.
## Distro-specific notes
This following sections provide information that is specific to a particular Minimal TemplateVM distro.
### Fedora
The following list provides an overview of which packages are needed for which purpose.
As usual, the required packages are to be installed in the running template with the following command (replace `packages` with a space-delimited list of packages to be installed):
- Commonly used utilities: `pciutils``vim-minimal``less``psmisc``gnome-keyring`.
- Audio: `pulseaudio-qubes`.
- [FirewallVM](/doc/firewall/), such as the template for `sys-firewall`: at least `qubes-core-agent-networking` and `iproute`, and also `qubes-core-agent-dom0-updates` if you want to use it as the `UpdateVM` (which is normally `sys-firewall`).
- NetVM, such as the template for `sys-net`: `qubes-core-agent-networking``qubes-core-agent-network-manager``NetworkManager-wifi``network-manager-applet``wireless-tools``notification-daemon``gnome-keyring``polkit``@hardware-support`. If your network devices need extra packages for the template to work as a network VM, use the `lspci` command to identify the devices, then run `dnf search firmware` (replace `firmware` with the appropriate device identifier) to find the needed packages and then install them. If you need utilities for debugging and analyzing network connections, install `tcpdump``telnet``nmap``nmap-ncat`.
- [USB qube](/doc/usb-qubes/), such as the template for `sys-usb`: `qubes-usb-proxy` to provide USB devices to other Qubes and `qubes-input-proxy-sender` to provide keyboard or mouse input to dom0.
- [VPN qube](https://github.com/Qubes-Community/Contents/blob/master/docs/configuration/vpn.md): Use the `dnf search "NetworkManager VPN plugin"` command to look up the VPN packages you need, based on the VPN technology you'll be using, and install them. Some GNOME related packages may be needed as well. After creation of a machine based on this template, follow the [VPN instructions](https://github.com/Qubes-Community/Contents/blob/master/docs/configuration/vpn.md#set-up-a-proxyvm-as-a-vpn-gateway-using-networkmanager) to configure it.
-`default-mgmt-dvm`: requires `qubes-core-agent-passwordless-root` and `qubes-mgmt-salt-vm-connector`.
In Qubes 4.0, additional packages from the `qubes-core-agent` suite may be needed to make the customized minimal template work properly.
-`qubes-core-agent-nautilus`: This package provides integration with the Nautilus file manager (without it, items like "copy to VM/open in disposable VM" will not be shown in Nautilus).
-`qubes-core-agent-thunar`: This package provides integration with the thunar file manager (without it, items like "copy to VM/open in disposable VM" will not be shown in thunar).
-`qubes-core-agent-dom0-updates`: Script required to handle `dom0` updates. Any template on which the qube responsible for 'dom0' updates (e.g. `sys-firewall`) is based must contain this package.
-`qubes-menus`: Defines menu layout.
-`qubes-desktop-linux-common`: Contains icons and scripts to improve desktop experience.
-`qubes-core-agent-qrexec`: Qubes qrexec agent. Installed by default.
-`qubes-core-agent-systemd`: Qubes unit files for SystemD init style. Installed by default.
-`qubes-core-agent-passwordless-root`, `polkit`: By default, the Fedora Minimal template doesn't have passwordless root. These two packages enable this feature.
-`qubes-core-agent-sysvinit`: Qubes unit files for SysV init style or upstart.
Also, there are packages to provide additional services:
-`qubes-gpg-split`: For implementing split GPG.
-`qubes-u2f`: For implementing secure forwarding of U2F messages.
-`qubes-pdf-converter`: For implementing safe conversion of PDFs.
-`qubes-img-converter`: For implementing safe conversion of images.
-`qubes-snapd-helper`: If you want to use snaps in qubes.
See [here](https://github.com/Qubes-Community/Contents/blob/master/docs/customization/fedora-minimal-template-customization.md) for further information on customizing `fedora-minimal`.

- NetVM, such as the template for `sys-net`: `qubes-core-agent-networking``qubes-core-agent-network-manager`. If your network devices need extra packages for a network VM, use the `lspci` command to identify the devices, then find the package that provides necessary firmware and install it. If you need utilities for debugging and analyzing network connections, install the following packages: `tcpdump``telnet``nmap``nmap-ncat`.
- [USB qube](/doc/usb-qubes/), such as the template for `sys-usb`: `qubes-usb-proxy` to provide USB devices to other Qubes and `qubes-input-proxy-sender` to provide keyboard or mouse input to dom0.
- [VPN qube](https://github.com/Qubes-Community/Contents/blob/master/docs/configuration/vpn.md): You may need to install network-manager VPN packages, depending on the VPN technology you'll be using. After creating a machine based on this template, follow the [VPN howto](https://github.com/Qubes-Community/Contents/blob/master/docs/configuration/vpn.md#set-up-a-proxyvm-as-a-vpn-gateway-using-networkmanager) to configure it.

-`qubes-desktop-linux-common`: Contains icons and scripts to improve desktop experience.
Also, there are packages to provide additional services:
If you want to use interactive dialogs, (e.g file selection), you will need to add the `zenity` package. ([Here's an example](https://github.com/QubesOS/qubes-issues/issues/5202))
You could, of course, use `qubes-vm-recommended` to automatically install many of these, but in that case you are well on the way to a standard Debian template.
