Switching to Linux

[queer_scribbling]

I keep finding myself too busy to switch my main laptop to a Linux option, and Windows 10 ended support *mumble mumble* months ago. (I don't have enough space for Windows 11, and I'm not feeling very enthusiastic about what I've heard about it.) This weekend is when I need to make the switch. Right now, I'm thinking of Linux Mint (probably Cinnamon).

If there isn't a comment from me that I finally made the switch by Sunday, someone can leave something in the comments as a nudge.

Step Two. Verify the ISO.

This step is making sure all the stuff is there and correct. There's a forum post on How to verify the ISO image on Windows (posted in 2019).

First, I need to go back and put the files in their own dedicated folder instead of letting them chill at the top of the Downloads folder.

Then browse to https://www.gnupg.org/download/index.html and download and install the Windows installer for GnuPG. It is this download:

For the purposes of this guide it does not matter whether you install the program as administrator or not, so just click yes to install to install without administrator rights if it asks you.

Well, I need to get this sorted out before worrying about the commands.

Now find the folder containing the files you downloaded in the first step, hold Shift while right-clicking it (the folder, not the files in it). Select to open a command window:

[Arrow pointing to option in menu: Open command window here]

Depending on your version of Windows it is also possible that the option is called like this:

[Open PowerShell window here]

Use whichever you've got available but if you used the PowerShell option then type cmd followed by Enter into the window.

Shift, left click, and 'Open PowerShell window'. cmd, Enter. Great.

Integrity Check
Type this command into the command window while replacing the filename.iso part with the actual name of the .iso file you downloaded:

CertUtil -hashfile filename.iso SHA256

Press Enter to run the command.

CertUtil -hashfile *linuxminut-22.3.cinnamon-64bit.iso SHA256 [Enter]

A string of numbers and letters! (Sarcasm redacted in favor of just editing above comments to note to keep all the files together in the requisite folder.) Open sha256sum.txt and confirm that string matches the string next to *linuxmint-22.3-cinnamon-64bit.iso.

See: Authenticity check

There are so many strings of numbers in this part that I just copied and pasted from the linked page.

gpg --keyserver hkp://keys.openpgp.org:80 --recv-key 27DEB15644C6B3CF3BD7D291300F846BA25BAE09 [Enter]

gpg --list-key --with-fingerprint A25BAE09 [Enter]

The output should contain 27DE B156 44C6 B3CF 3BD7 D291 300F 846B A25B AE09 and look like this:

pub rsa4096 2016-06-07 [SC]
27DE B156 44C6 B3CF 3BD7 D291 300F 846B A25B AE09
uid [ unknown] Linux Mint ISO Signing Key <root@linuxmint.com>

Finally:

gpg --verify sha256sum.txt.gpg sha256sum.txt [Enter]

The file signature is good and that 27DE string is back.
