SelfSolved - Updates, dvd drive, timeshift mess. No boot

[DumbMechanic]

After the last update my dvd burner started to open-close randomly so I decided to use timeshift for the first time. Now my system is totally unbootable. Just a black screen.

Welcome to the forums.

You've found the bug in the last update.
See here:
viewtopic.php?f=47&t=356654

Anyway - to give your computer a chance to be fixed, can you boot up to Live Mint (USB/DVD) and run Timeshift from there.
That should get you back to whichever snapshot you choose. If I were you I'd go for the one just before the update and if for some reason that doesn't work, try the next one etc.
Let us know how it goes.

If there is still a problem, boot back into Live Mint and follow the instructions at number 5 in the following link so we have more info about your system:

I reformatted and everyrhing was ok till I updated again.
I was thinking that the erroneous update would be fixed quickly but no.
I formatted again but now I'll be smarter. No updates and timeshift for me.

Use Timeshift for sure if you have the disk space for the snapshots.

Open System Info to figure out what kernel you are using. If it is the 5.4 series, you can update up to 5.4.0-81-generic if that is an option. Beyond that your CD door will start cycling. We are all sticking with older kernels until this is fixed. Thanks for confirming that it is not fixed yet

Please don't stop doing updates, the problem with the DVD drive opening and closing is coming from the kernel, so when you get a notification that there are updates, look for the kernel in Update Manager and uncheck the update box, then do the rest of the updates.

It's also a good idea to use Timeshift, if something goes wrong, you can use it to go back to the original configuration instead of reformatting and reinstalling.

I will stop. It's a third time I reinstall in 7 months because of updates. Let's see how much it will last without updates. I have a backup, there is no sensitive stuff on my pc and I don't handle bank accounts. Except this account I'm not on any social network also. And I'm home behind a router with no strangers logged in. I will just update firefox.
I have nothing to fear.

Frankly, that is a rather unwise decision, but it is yours to make, there is always something to fear. The internet is wonderful, but it can also be a dark and unforgiving place. I wish you good luck.
