Debian boot error - XZ compressed data is corrupt

Postby Neranus » 2019-02-03 13:20

I do use Debian 9 for about one month, but know I can't boot over Linux, if I try to I got an error-alert "Xz-compressed data is corrupt --System halted". I do even have an Windows 10 at the same hard drive and I can boot over windows without any problems.
My processor is an Intel(R) Core(TM)2 CPU 6320 @ 1.86GHz
x64-based processor
Does anyone know, why this happens and -eventually- how to fix it?


P.s. I'm sorry for any grammar mistakes, because english is not my first language

Bad RAM, perhaps?

I can't remember if memtest is included in the Debian ISO image boot options, try starting it in non-UEFI mode (it won't work otherwise).

I searched the error message on your behalf (you're welcome) and one thread stated that re-seating the CPU removed the error.

Many other suggestions available from your favorite search engine :)

Many people return a problem about RAM when "XZ-Compressed data is corrupt" and like Neranus I can confirm in our case it's nor linked to RAM issue. In his case, he have a dual boot machine with Windows where no problem with RAM... In my case, my Debian 10 (32-bit) machine is a VM in Oracle Virtualbox.

I tried to export my machine to another host and the issue is the same.


How to fix a corrupted machine that want to boot, then return this error:

Code: Select all
XZ-Compressed data is corrupt

-- System halted

without reinstalling from scratch. I have a big webserver on my VM that could need a lot of work to reinstall... This server is running since many years starting on Debian 5 upgraded to Debian 6, 7, 8, 9 and 10 since 6 mothns without problem... !!!

It probably exist a method to run a LiveCD to fix startup ?

It could be a kernel image (/boot/vmlinuz-*) corruption. Try reinstalling the kernel.
