Unable to verify Ubuntu 21.04 ISO

fk flag

ubuntu 21.04 download verification failure. trying to verify download with command: ubundu 21.04$ echo "fa95fb748b34d470a7cfa5e3c1c8fa1163e2dc340cd5a60f7ece9dc963ecdf88 *ubuntu-21.04-desktop-amd64.iso" | shasum -a 256 --check. It says run this command in your terminal in the directory the iso. Is iso files are part of this download? because when I run command in the download folder, I get failure message below:

me@me:~/Downloads/ubundu 21.04$ echo "fa95fb748b34d470a7cfa5e3c1c8fa1163e2dc340cd5a60f7ece9dc963ecdf88 *ubuntu-21.04-desktop-amd64.iso" | shasum -a 256 --check
shasum: ubuntu-21.04-desktop-amd64.iso: 
ubuntu-21.04-desktop-amd64.iso: FAILED open or read
shasum: WARNING: 1 listed file could not be read

If ISO files not a part of ubuntu 21.04 download, where do i get them? and do i have to save then under the same /Downloads/ubundu 21.04 directory? After download, how do I install ubuntu 21.04? Thank you.

Why you do not want to use `cd ~/Downloads/ubundu\ 21.04 ; wget https://releases.ubuntu.com/hirsute/SHA256SUMS ; sha256sum -c SHA256SUMS` ?

It seems that you are unable to find the location of the iso from the command line, I would suggest you check it with a GUI program.

Install gtkhash with the command

sudo apt install gtkhash

gtkhash

Select the .iso file in gtkhash, and generate the SHA256 sum.

Copy the given SHA256 hash in the Check textbox, and the software would show a checkmark if they match.

Afterwards, follow the official tutorials for creating a bootable live USB, and using it to install Ubuntu.

Thank you for your suggestion. did all of it. GTKhash confirmed 2 checkmarks and both match. How it helps me to install ubuntu?

@iirniak It means that the iso is not corrupt, and it can be used to install Ubuntu. Now you have to create a live USB and boot it to install Ubuntu (there are excellent tutorials, just search for it).

I just learned that my machine is i386 architecture and Ubuntu will not support this architecture. I guess it is a reason I am not able to download Ubuntu 21.04. Any suggestions on what I can update my machine too? Doesn't have to be ubuntu. Can do any linux operational system, as long as it is newest

which newest Linux operational system I can install on i386 architecture laptop?

@iirinak I suggest you go with Debian XFCE edition. https://www.debian.org/ Here is the download link for ISO. https://cdimage.debian.org/debian-cd/current-live/i386/iso-hybrid/debian-live-11.0.0-i386-xfce.iso Here is the download link for torrent of the same https://cdimage.debian.org/debian-cd/current-live/i386/bt-hybrid/debian-live-11.0.0-i386-xfce.iso.torrent By the way, how much RAM do you have?

Archisman, seem I have 1609148 RAM, if I am reading correct. > "me@me:~$ $ free $: command not found me@me:~$ free total used free shared buff/cache available Mem: 8122548 1609148 4198788 460124 2314612 5392872 Swap: 2097148 0 2097148". So I have to create live USB on Ubuntu 21.04?
us flag
@iirinak Yes, you have to create a live USB, and boot with it. Just search in your favorite search engine something like "how to create a live USB in Ubuntu"

Thank you Archisman. I just learn that my laptop can run on both, I386 and I689. So I can still get Ubuntu 21.04. do I have to format USB stick to particular format? But I would love to try Debian XFCE edition. Thank you very much for your guidance. If I have trouble with installation live USB, can I email you directly plz?
us flag
@iirinak You can also try Xubuntu, which is XFCE edition of Ubuntu (in general, Ubuntu is slightly more user friendly than Debian). But with 16 GB ram, even regular Ubuntu would work very well. I have edited my answer with link for live USB and installation. You can ask a new question or comment here if you face any problem. If the problem persists, I would share my email.

@iirinak By the way, it would be a good idea to perform a fresh install of 21.04 rather than an "upgrade install", because the "upgrade" can lead to installation of a lot of unnecessary packages which were necessary in 18.04, but are not anymore required in 21.04.

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.
