oh forgot the second part.

first of all. .pub files are not microsoft owned keyfiles, but Microsoft Office Publisher documents. this is irrelevant now, but this is the only connection of microsoft with .pub files

second of all, .pub files can also be OpenPGP public key files. do you use SSH? look into your ~/.ssh/ directory and you will see them there too. also in /etc/ssh/

You can find multiple instances when they are revoked keys and people on stack exchange are figuring out how to update them to use the toolkit after the change.

yeah, signing keys expire from time to time and then they need to be replaced or updated. but these are not per-user, these are public and cannot be kept in secret. this is not a subscription code, not a DRM either, it’s one of those very few exceptions when they are provided for actual security. the packages you download are already signed with the key, if you don’t accept the key your package manager just wont be able to verify if they have been tampered with while in transit. if you don’t accept the key, you can still install the packages, but then you also need to pass the parameter to your package manager that tells it to not verify the packagesthis time, which is 99.999% of the cases a bad idea.

these warnings are interesting, but -Wno-deprecated-gpu-targets makes me think maybe your card is nearing end of support for CUDA. after that youll need to install an old version of cuda manually (or pin the package versions and risk them silently keeping back other packages too)

what card is it?

also, please take screenshots with the system’s screenshot tool because this is so bad. I mean, multi-megabyte screenshots…

also, I don’t understand how mirrors, gcc and clang come into picture. or Microsoft

on my distro its common that all repositories use their own signing keys to sign the packages they provide. this includes the nvidia repository. I think here you are prompted to save their key so that your package manager can accept their packages.

I might be wrong, though. next time you could check what happens if you type N. my expectation is that the package manager will throw errors about unverifiable packages

what kind of key file do you mean? where do you see it?

i don’t think this is a good idea. govs could just set up a big reverse proxy for lots of sites to serve them with their own certs, and you wouldn’t know

mirror!!44!!!

I’ll assume you have taken the leak after going to the fridge

so if the battery is dead […] and you drive away.

what do you mean?

Because as you suspect, an image backup cannot be done while the partition being imaged is live.

can’t it, though?

macrium reflect’s normal operation is to run when the ststem is running normally. it creates a volume shadowcopy of your filesystem, and backs that up. a BTRFS/ZFS snapshot is basically what a volume shadowcopy is on windows, but with a less fancy name. if you make a snapshot, you can back that up, either with zfs send, btrfs send, rsync, borg backup, whatever. the difference is that on linux it’s not possible to notify programs that a snapshot will happen please sanitize your databases, while windows does that too, so if you restore on linux that’s like if your computer crashed because power went off

sure, it can’t be done with other filesystems, but OP said they have BTRFS. I think the boot partition can be safely imaged too: remount as read only and make a normal image.

you forgot to post your sources

any normal music player works/can work that way on windows and linux

And I hate it too when it goes to the next song and this banner slowly fades in at the top of my screen to tell me what song it is and it also just pauses everything for a moment just for that. There’s other ways I can tell what you’re playing, I don’t need that.

you can turn that off in the settings. Actually I was pretty happy that it works on linux through wine. but if you can’t find the option, let me know, I have managed to find it recently I think

you can choose whatever email provider you trust, and then they apply encryption on the transport level. but there is often very few phone companies, and zero encryption. they don’t have to install any kind of wiretaps, they can just record everything automatically that passes through

I did it accidentally with my UPS. It didn’t like it and zapped me a little

Possibly helped somewhat for older machines where pressing the button made the fans spin for a little, but modern systems are somehow smart enough to not even bother doing anything

why use a case at that point, lol

is it a good idea to microwave that plastic container, though?

but that depends on the vendor. highest chance to do it is with Monero, even considering that basically no one knows it
