Comment or remove the sources.list in the error message that is causing the problem.

How can I do that? Tell me.

You can try this:

First, open your terminal. (You can often do this by pressing CTRL + ALT + T, but it's also in your application menu.)

Start by entering the following. You should be able to cut and paste, if you want to save some time.

sudo mv /etc/apt/keyrings/boot-repair.gpg /etc/apt/keyrings/boot-repair.gpg.bak

Then run:

sudo apt update && upgrade

When that finishes, run this command:

sudo apt install blender

It has been a while since I've seen this error. I'm not 100% sure that it will work. I'm not sure if you'll need to manually edit your sources to remove a repository. That may be what you need to do. Because I'm not certain, we're just renaming the file and not removing the file. (It's a trivial amount of disk space as it's just a plain text file.)

If this doesn't work, you can just run the following command to be back exactly where you were:

sudo mv /etc/apt/keyrings/boot-repair.gpg.bak /etc/apt/keyrings/boot-repair.gpg

That will put you back into the same situation you're currently in with nothing additional broken.

 

[KGIII]

Also, I am not sure that you needed to add the repo for boot-repair. I think it's in the default repos already. You could very likely have installed it with sudo apt install boot-repair and been just fine.

I'll also mention that some users have had issues with boot-repair in the past. I can't say that it has ever caused me a problem but it has been problematic for others - especially if you have a complicated boot environment. If it's your only OS installed on the system it's likely fine, but you've been warned.

Then, I'll ask why you have it installed in the first place? Are you having boot issues? If so, we should address those if they're not already addressed.

I'll also add that there's a 'boot-repair' live Linux that is in .iso format. You write it to USB like you did for your Ubuntu .iso file and then boot to it. It then has the boot-repair tool installed.

It looks like that almost all digital steps something went wrong.
Take a look at it,please?

Yeah, you still have the wonky PPA in your list.

I don't have an Ubuntu handy but you can open your sources and remove the tick next to the entry (which will update the system). It should be under 'Software Sources' as I recall. You'll find the PPA in one of those entries and can untick the box and save the changes.

You are using GNOME with Ubuntu, right? If so, the above should be correct.

Well thanks,but it seems that it's not working.

You did remove the PPA, right? That should solve this and let you install Blender.

At least I was trying,but nothing happened.

Does ubuntu have a software Manager?.....I am not familiar with it, otherwise I would know.

Linux Mint 22.1, has a Software Manager......I opened it and typed in blender and had it installed in a minute or two

Are there any other dramas/problems/weird happenings with your Ubuntu install ?.......Is it worth reinstalling ?

Do you really think that I should consider re-installing Ubuntu Linux?

 

[Condobloke]

if you are getting other weirdness/mistakes in the operation of that distro....Yes.

First, I think you should search the menu area for some sort of Software Centre

Will I be able to find some emulators?

 

[Condobloke]

Why complicate it even further?

if you wuish to download blender, find the software centre in ubuntu 24.04 and download it from there. it should be a simple straightforward task.
The link I left on post #14 will guide you to find and use the software centre

This thumbnail reminds me of for instance Apple App Store,Microsoft Store which are popular nowadays…etc.

I know everyone here will usually tend to give distro-specific package-management instructions. That is, after all, how most software is installed for us.

With Blender, there IS another option.

Blender is a self-contained package. The entire thing is contained within a single directory. You can visit the Blender website, and download the current tarball. Extract it inside your /user/home directory - this removes the need to use sudo - then open a terminal inside the blender directory and run the launcher.

It SHOULD fire-up. Mind you, I wouldn't like to say; with Canonical going Snap-centric now, I couldn't even say if the dependencies would be available.....I haven't used Ubuntu for well over a decade.

It's a "last resort" type of thing, but the option IS there.

Recommended method to install blender is to download it from blender website and install into /opt directory, then make a *.desktop file and put into right place: ~/.local/share/applications

How to do that? I mean how can I do that? Tell me even more further details,please?

How to do that? I mean how can I do that? Tell me even more further details,please?

Here is a template for *.desktop file

[Desktop Entry]
# 3 types of desktop entries: Application, Link and Directory
Type=Application
# Specific name of the application
Name=program
# Generic name of the application
GenericName=
# Path to an executable file on disk used to determine if the program is actually installed
TryExec=
# Program to execute, possibly with arguments
Exec=/opt/program
# If entry is of type Application, the working directory to run the program in.
Path=
# Icon to display in file manager, menus, etc
Icon=/opt/path/to/program.png
# Tooltip for the entry
Comment=Program Comment
# Categories in which the entry should be shown in a menu
Categories=Game
# A list of strings which may be used in addition to other metadata to describe this entry
Keywords=keyword
# Whether the program runs in a terminal window
Terminal=false
# This application exists, but don't display it in the menus
NoDisplay=false
# If true, the application has a single main window, and does not support having an additional one opened
SingleMainWindow=true

Download blender from here:

Download — blender.org

Blender is free and open source. Forever.

www.blender.org

Extract the archive into /opt directory as follows:

sudo tar -xvJf blender-4.4.0-linux-x64.tar.xz /opt

Then update template file with correct paths and put it into ~/.local/share/applications
Name the file blender.desktop
When done log out and log in again, and the shortcut should appear in your desktop menu. (assuming you did all right)
