ISO files are corrupted

I’m trying to download and install Ubuntu MATE on my old Acer Aspire One netbook, but every time I download the ISO file, it is corrupted. I’m burning it to a USB drive via Win32 Disk Imager, and it will successfully burn, but when I use the verify only option, or try to install Ubuntu MATE from the thumb drive, it usually says it’s corrupt in sector 0. I have tried multiple different sources for the download and none of them seem to work. I won’t use the torrent file because I don’t like P2P programs. Can anyone help?

Sounds like it could be a bad thumb drive or it needs to be thoroughly reformatted. That usually fixes those problems for me.

Yeah, gotta go with @grenouille on this.
If you want to check the ISO files, the checksums are available on the download page and tools to do that are listed here: http://ubuntu-mate.org/how-to-verify-downloads/

The checksums are the same but when I reformatted the drive, it still says “Verification Failed at Sector 0” and now when I try to burn the ISO to the drive it gives me Error 1110. Does it matter if I do a quick format or a full format? @ouroumov @grenouille

Toss the drive. They are so cheap these days, that it’s just not worth the effort you’re putting in. Oh, and yeah, a full format is better, but I seldom do it as I’m lazy that way. I don’t think it will solve your problem, though.

I don’t really want to buy a new drive so I’m just going to do a full format and see how that goes. The thing is, I can usually still burn the ISO and boot into it successfully, I just can’t install it.

I’ve tried 2 different USB drives and an SD card and they all say “Verification Failed at Sector 0” when I do Verify Only in Win32 Disk Imager. Do you think it could be Win32 Disk Imager, or maybe my motherboard?

Could be, I usually use Universal USB Installer. Always worth a try.

As far as your motherboard goes, again, it is possible, but much less likely. If you can, try it on another computer or even a different port on yours.

Alright I’ll try those out if this SD card doesn’t work. I just burned it using Rufus without any errors apart from this one when I start the boot drive: “[ACPI] Namespace lookup error: AE_ALREADY_EXISTS”
Would this be because of a faulty drive or USB port? @grenouille

@takochako Perhaps you should try rufus. It is a great tool for burning install iso’s to USBs.

Rufus successfully burned the ISO to the SD card. I’m currently testing the installer to see if it will work.

Probably not. I have a couple of older machines that throw errors like that at boot - often relating to ACPI. Did it continue to boot otherwise? If so, I wouldn’t worry about it.

So I think it was Win32 Disk Imager causing the problem! I got the same ACPI error on the SD when I burned the ISO using Rufus, but I have successfully installed Ubuntu MATE, and it runs incredibly smooth (considering the 512 MB of RAM xD)! There were some warnings popping up in the console during installation, but I don’t think it was anything problematic. Thank you all for helping me with this problem! @grenouille @mdooley

Welcome to the forum @takochako. Glad your problem was resolved.
