First check how many memory sticks you have. If you have more than one then test each with memtest86+ (one pass will be enough). If one gives no errors they you don't need to replace that stick.

You *might* find that one of the sockets in the motherboard is faulty so the memory will work correctly in another socket. Or if you are really lucky just removing and replacing the memory will clean the connections and make it work.

It might be worth checking it still works after one or two more reboots before you mark it as solved. I've see strange things happen too often to trust software to always do what you expect.

What sort of graphics card have you got? Or if you are using onboard graphics what sort of CPU is it?

Try assigning it an IPv4 address manually to get ethernet working. Eg ifconfig eth0 addr 192.168.1.64/24 as root. Replace eth0 with whatever the link is called. And use an address nothing else you have is using.

That would only be a temporary fix, but would enable you to download fixes onto it.

Or post output from /sbin/ifconfig here to give us a bit more to go by.

What make and model of system is it? CPU, motherboard, manufacturer, etc? Are you booting from a USB drive or a DVD? In either case what model?
Do any messages come out during the boot process?
If you have more than one system does it respond to pings from another system? If so can you log on to it over the network?
Exactly what message came out about the "live-boot" package when booting the minimal install? Can you take a photo of the screen and post it somewhere?

The problem here is that microsoft is an effective monopoly. Capitalism works well if you have a choice of product to buy, eg cars. But most people have to buy the OS with most software written for it, and most software is written for the OS with most users. So just because microsoft got there first they won control of the desktop. Ditto Intel nearly control the hardware market, though AMD do provide some competition.

WSL is intended to help them keep control by allowing people who need software only available on Linux to stay on windoze.

Nothing but US government intervention could break microsoft's monopoly (eg by requiring that the source code for any OS be made publicly available). And don't hold your breath waiting for that to happen.

It's a similar story with facebook (most people use it because most of their friends use it). And google etc.

Also check if the filesystem it is in is mounted read-only, Eg mount | grep /mnt/sd8

If all else fails copy everything you want to keep from that filesystem to somewhere safe, then re-format it.

I'd try apt-get --simulate autoremove first and see what it said it would remove (or apt --simulate autoremove). Then double-check it wasn't saying it would remove anything current.

https://gist.github.com/npcardoso/47d8f … wakeups-sh has backticks round grep '\*disabled' /proc/acpi/wakeup | cut -d ' ' -f1 and grep '\*enabled' /proc/acpi/wakeup | cut -d ' ' -f1. Those tell bash to run the command inside the backticks and assign the output from it to TOGGLE.

You could use $(...) instead, it's easier to read if you don't get muddled about what sort of brackets to use.

There are a number of text consoles, accessed by ctrl-alt-F1, ctrl-alt-F2, etc. ctrl-alt-F7 should take you back to the GUI if that's working (it might be some other combination such as ctrl-alt-F6 so it's worth testing before you need it in anger).

And did the logs show anything from the last time it happened? Although I've had systems lock up or suddenly reboot with nothing interesting in the logs before the messages from the system coming back up.

Try memtest86 (first single threaded, then multi). If that fails it's not the OS causing it.

Could you put the old CPU back in and see if that still works OK?

Try running watch sensors in another window and see if the system gets too hot under load. If you have another system log on to the faulty one (eg by ssh) and run it. That way you could still see the last screenful of output.

Try other stress tests. If it's stable under CPU load but not graphically intensive ones that might point to the error.

But it's odd the OS needs to be re-installed after a few crashes. What are the symptoms in that state?

Please post the segfault log entries here (and a few each side of the segfaults).
