## Checksum Verification
|
|
|
|
### Using GnuPG
|
|
|
|
To verify the PGP signature with GnuPG, first download the release signing key from
|
|
[WKD (Web Key Discovery)][wkd] or any key service that you trust.
|
|
|
|
```sh
|
|
gpg --auto-key-locate clear,wkd -v \
|
|
--locate-external-key pierre@archlinux.org
|
|
```
|
|
|
|
Then use the obtained key to verify the signature of the downloaded file
|
|
|
|
```sh
|
|
gpg --keyserver-options auto-key-retrieve \
|
|
--verify archlinux-<version>.iso.sig
|
|
```
|
|
|
|
### Using an existing Arch Linux System
|
|
|
|
On a system already running Arch Linux, `pacman` can be used to verify the Installation Medium.
|
|
|
|
```sh
|
|
pacman-key -v archlinux-<version>.iso.sig
|
|
```
|
|
|
|
## Create a Bootable Medium
|
|
|
|
Create a bottable medium from the downloaded **and verified** Arch Linux ISO.
|
|
For example, a bootable USB flash drive.
|
|
|
|
Execute the following command to copy the downloaded ISO to the USB flash drive.
|
|
|
|
> Important: The following command will permanently delete the data of the destination device.
|
|
> Make sure to specify the correct destination device and to back up important data prior to executing
|
|
> this command.
|
|
|
|
```sh
|
|
dd bs=4M \
|
|
if=<path to archlinux iso> \
|
|
of=/dev/disk/by-id/usb-<your flash drive> \
|
|
conv=fsync oflag=direct status=progress
|
|
```
|
|
|
|
> Tip: After you are done using the USB flash drive for the Arch Linux installation, the following
|
|
> command must be executed to delete the ISO 9660 filesystem signature from the device to use it
|
|
> as a normal USB flash drive again.
|
|
>
|
|
> ```sh
|
|
> wipefs --all /dev/disk/by-id/usb-<your flash drive>
|
|
> ```
