I have Windows 10 installed on an Asus and I want to switch to Ubuntu 22.04, so I tried to install Ubuntu. When I started the installation, I saw this error message. I tried everything, but at first nothing worked.

  • Your installation media is faulty (the SQUASHFS errors are errors reading your media). Did you verify your ISO after download? I'd use another machine to verify your write (if you don't have capacity of verifying write of ISO on your writing machine). You didn't specify which Ubuntu 22.04 LTS product (the installer is selected by the ISO you download; and you didn't specify, only mentioning the release itself; ie. 22.04). – guiverc Jan 22 '24 at 10:22
  • Does this answer your question? Is verifying ISOs downloaded from the official website worthwhile? – guiverc Jan 22 '24 at 10:22
  • A lot of details you didn't provide really matter; as 22.04 is newer than 20.04; the method of writing can matter (esp. if you're not using software that reformats the ISO via options & wasn't written to cope with the 22.04 release!). As you didn't specify what product, your kernel stack maybe a GA (5.15) or HWE (6.2) which can impact (due to age) what hardware it can cope with (you gave few clues as to your Asus hardware). Did you download & use an appropriate ISO for your hardware? an older or newer kernel stack on your 22.04 ISO? as you didn't mention which 22.04. – guiverc Jan 22 '24 at 10:28
  • FYI: Bad downloads are extremely rare in my experience; the write of the ISO to thumb-drive is the most common cause; either through error (by selecting inappropriate options for your hardware; a simple CLONE of ISO to media is most reliable as it'll work on legacy BIOS, uEFI & Secure-uEFI where as reformatted may not!) with updated ISO writing software, (there are many ISO types; not all software writes all types; stick to documented procedures for Ubuntu ISOs I'd recommend). If you're hardware is new, you may need newer software. – guiverc Jan 22 '24 at 10:32
  • The "SGX disabled by BIOS" message is just for information. It's not an error. – zwets Jan 22 '24 at 14:10
  • Changed the title to reflect the actual issue – Artur Meinild Jan 23 '24 at 10:21
