QA:Testcase_Mediakit_ISO_Checksums
|
Description
This test is intended to verify that the posted ISO media matches the published SHA-256 checksum. Additionally, for ISO media that includes an embedded MD5 checksum, this test verifies that checkisomd5 (used by the installer) correctly locates and verifies the embedded MD5 sum.
Setup
- Download the
.iso media files you need to test
- Download the matching CHECKSUM file. For example,
Fedora-42-i386-CHECKSUM .
How to test
- Validate that the published CHECKSUM matches the downloaded ISO files by running the command
sha256sum . For example, you might type: <pre<noinclude></noinclude>>sha256sum -c Fedora-42-i386-CHECKSUM</pre<noinclude></noinclude>>
- Validate the md5sum imprinted inside the ISO images. First, install the
isomd5sum package and then check all ISO files using the checkisomd5 command, for example: for ISO in Fedora-*.iso ; do echo "= $ISO =" ; checkisomd5 $ISO ; echo; done
Expected Results
- The command
sha256sum should return OK results. For example:
<pre<noinclude></noinclude>>$ sha256sum -c Fedora-42-i386-CHECKSUM
Fedora-42-i386-DVD.iso: OK
Fedora-42-i386-netinst.iso: OK</pre<noinclude></noinclude>>
- The command
checkisomd5 should either return:
The media check is complete, the result is: PASS.
It is OK to use this media.
or:
The media check is complete, the result is: NA.
No checksum information available, unable to verify media.
