Ubuntu - Option to encrypt drive during fresh install greyed out by display_name1 in c/[email protected]

Thank you for this. I did give this an attempt, I didn't find the manual partitioning. I found an option to create a new partition table, I don't think I was in the right spot. I couldn't figure out how to configure the one partition just for boot, and what to select on the drop down menu. "Physical encryption volume?"

I think I'll just create an encrypted folder until hopefully a fix is made for the installer.

Ubuntu - Option to encrypt drive during fresh install greyed out (lemmy.world)

I'd like to do a full disk encryption. I realize I cannot do this since I've already installed ubuntu, so I'm fine with doing a fresh reinstall.

The problem is when I get to the step of selecting "wipe entire disk and install ubuntu", then click on Advanced settings, the option for full disk encryption is greyed out. It is the only option that is greyed out, I am able to select the other three.

What gives here? I'm wiping the disk and installing from a usb so why wouldn't it allow me to encrypt? The only thing I can think of is I might have some strange setting wrong in the BIOS, but I'm not a computer guy.

Thanks everyone I was finally able to change my root password after a reformat.

So if I boot into recovery mode, and it does end up asking me for a password again, does that imply a bad actor has changed my root password? If that's the case, will a fresh install solve my problem?

I'm very new to linux so I'm not really sure what best practices you should follow after an install. Should you immediately change your root password and install a firewall, first steps taken?

It just says "Sorry, try again" after a failed attempt to enter the sudo password.

I am certain I am inputting the same password that I am using for authentication during login. Certain in the sense that I have triple checked that I am typing the correct keys on my laptop keyboard, and the password only contains lower case letters.

In terms of keyboard layout, I have confirmed I am using US. Is there a different password specific for sudo that I am missing here? I've never set the password for root, since this requires the use of sudo and I've never been able to access sudo.

The problem: Each time I try to execute the sudo command, and type the correct password, it rejects the password.

I am at the end of my rope with internet searches, I’m close to just wiping and trying an operating system reinstall.

I am new to linux and I recently installed ubuntu 22.04.3. I haven’t been able to access the sudo command since the install. I’m currently attempting to install firewalld, but I’m going to need this command for other things as well and I’m starting to wonder if there is something wrong with my install or worse.

Many of the troubleshooting techniques I’ve come across contain a catch 22 in that they require the sudo command to solve this, which I am unable to execute.

Edit: Thanks to everyone who helped me with this issue. Update. I tried a first disk erase and install of ubuntu. During the first attempt I went through the software updates and I did a few things like changing firefox settings before attempting to change my root password. I was unable to change the root password when I attempted to.

Attempt #2. I reformatted and immediately tried to set my root password and this time it worked, and I have had no issues since. So take all of that for what it’s worth.
