How to create up to date ubuntu iso image to install from?

nr flag

During and after installation of ubuntu 20.04.2.0 i experienced a good deal of obstacles. First i had to switch to onboard gpu to even be able to install , then i had to install the proprietary nvidia 340 drivers , then had to download over 600 MB of updates to be able to enjoy system without " internal error" when entering settings utility . Now i would like to create a complete iso image that i could install from without all the hassle i went through, that would install all the updates and nvidia drivers being offline. Is it possible and how to do it? Or is it somewhere available as download?

Cubic may work for you: https://askubuntu.com/a/1291054/43926, I just create an image file, (.img) of the system I want to duplicate: https://askubuntu.com/questions/1300540/how-to-duplicate-a-ubuntu-system-for-distribution which I find a lot easier.

Are you intending to install the system in other computers? I'm asking because there may be problems with the proprietary graphics driver in some computers (if an nvidia chip/card that does not work you the driver that you have installed).

yes i want to be a universal installer for different computers.

Then Cubic may be a good alternative. A compressed image of an installed system would also be an alsternative, but the proprietary graphics driver is an obstacle for some computers.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
