All the apprehension in the comments are valid. Many govt departments have adopted linux in the past but continues using Windows. Seen a few govt supplied devices come with dual boot with Win and some custom debian distro but those are seldom used.

Most of India, like the world, is heavily reliant on MSOffice suite. And the govt cant get enough of documents, so unless they have a good migration plan off of office or have them pre-installed on their linux distro, this itself would be a major pain point.

Other than that, of the govt employees I've seen in the education field, most are pretty computer illiterate. They basically use the browser, file explorer and office and only learn enough to do that. So migrating them to linux would work if they are willing to learn the minimal platform differences with those.

So unless these departments have incompatible software or sites that only work on IE this might work. You might think its cant be that bad but many places used floppy till some 5-7 years and have successfully transitioned to CDs for submitting internal department documentations. Although recently many use whatsapp and use DVDs for archival. Then theres are the poorly designed portals launched with every new government scheme. Many of those function poorly on firefox.
