!!! info "Associated release criterion"
|
|
This test case is associated with the [Release_Criteria#initialization-requirements](9_release_criteria.md#initialization-requirements) release criterion. If you are doing release validation testing, a failure of this test case may be a breach of that release criterion.
|
|
|
|
## Description
|
|
This verifies that Rocky Linux ISO image can be written to USB media using `dd` command, and the resulting USB media successfully boots to the Anaconda Installer.
|
|
|
|
!!! error "DATA LOSS"
|
|
Any data on the USB stick used for this test is likely to be destroyed. Please do not use a stick whose contents you need to keep.
|
|
|
|
## Setup
|
|
|
|
1. Provide a USB media device that is larger than the ISO image you wish to test and that it can be completely erased.
|
|
2. Provide a Linux (or other *nix system) that has the `dd` command available and an unoccupied USB port.
|
|
3. Download the Rocky Linux ISO image you wish to test onto the test system.
|
|
- Example command:<br>`curl -LOR https://dl.rockylinux.org/pub/rocky/8/isos/x86_64/Rocky-x86_64-boot.iso`
|
|
4. Download the `CHECKSUM` file that goes with the Rocky Linux ISO image that you wish to test.
|
|
- Example command:<br>`curl -LOR https://dl.rockylinux.org/pub/rocky/8/isos/x86_64/CHECKSUM`
|
|
5. Download the `CHECKSUM.sig` file that does with the `CHECKSUM` file.
|
|
- Example command:<br>`curl -LOR https://dl.rockylinux.org/pub/rocky/8/isos/x86_64/CHECKSUM.sig`
|
|
6. Download the Rocky Release Engineering GPG key.
|
|
- Example command:<br>`curl -LOR https://dl.rockylinux.org/pub/rocky/RPM-GPG-KEY-rockyofficial`
|
|
|
|
## How to test
|
|
|
|
1. Import the Rocky Release Engineering GPG key.
|
|
- Example command:<br>`gpg --import RPM-GPG-KEY-rockyofficial`
|
|
2. Verify the signature of the CHECKSUM file.
|
|
- Example command:<br>`gpg --verify-file CHECKSUM.sig`
|
|
3. Verify the CHECKSUM of the Rocky Linux ISO...
|
|
- Example command:<br>`shasum -a 256 --ignore-missing -c CHECKSUM`
|
|
4. Write the Rocky Linux ISO to the USB media using `dd`...
|
|
- Example command:<br>`dd if=Rocky-8.5-x86_64-boot.iso of=/dev/sdX bs=16M status=progress oflag=direct`<br>...where you replace `sdX` with the device identifier of your USB media.<br>**This will destroy all data on the disk.**
|
|
5. Boot the test system with the USB media.
|
|
6. In the boot menu select the appropriate option to boot the installer.
|
|
7. **[OPTIONAL]** Proceed with installation on the test system.<br>**Depending on installer choices this MAY destroy all the data on the test system.**
|
|
|
|
## Expected Results
|
|
|
|
1. The gpg signature on the `CHECKSUM` file is valid.
|
|
2. The `CHECKSUM` of the Rocky Linux ISO is valid.
|
|
3. The Rocky Linux ISO is written to the USB stick without errors.
|
|
4. The USB stick boots without errors.
|
|
5. The Anaconda Installer starts without errors.
|
|
|
|
!!! error "DATA LOSS"
|
|
If you choose to complete the installation of the test system any/all data on the system may be lost. Please do not install on a system whose contents you need to keep.
|
|
|
|
**[OPTIONALLY]**<br>
|
|
6. The installation finishes successfully and, if the minimal or DVD ISO were used, the package repository on the USB stick (not a network based repository) was used for the installation.
