MD5 and SHA256 hashes for the QluMan 12.0.7.5 Singularity image don't match those shown in the Download page
by Beethoven Santos 30 Nov '24

Hi, Whenever I download the file `qluman-12.0.7.5-singularity.sqsh` and use the `md5sum` and `sha256sum` commands to check its MD5 and SHA256 hashes, I find that they do not match the hash values shown on the [Download page](https://qlustar.com/download/) for this version (all others are ok). For this reason, I believe that using this file is not safe and I should avoid it. Is this something on Qlustar's side? Could anyone confirm this issue? Best B. Santos

The Qlustar team is pleased to announce the first public release of QluMan HA as the new driver of the Qlustar HA stack.
