I am trying to create debian chroot with debootstrap, but I get this error:

$ fakeroot debootstrap --arch=arm64 --variant=minbase stable .
I: Checking Release signature
I: Valid Release signature (key id 4D64FEC119C2029067D6E791F8D2585B8783D481)
I: Retrieving Packages 
I: Validating Packages 
E: Couldn't download http://deb.debian.org/debian/dists/stable/main/binary-arm64/Packages

The problem is that there is only http://deb.debian.org/debian/dists/stable/main/binary-arm64/Packages.xz or .gz files in repository. How do I fix this? Debootstrap is from Fedora 41 repo.

I am going to buy a new graphics card and can't choose between Nvidia and AMD. I know that Nvidia has bad reputation in Linux community but how really it works? And I heard recently their drivers got better. What can you recommend?

P. S. I don't want any proprietary drivers (so I am talking about Nouveau or any other FOSS Nvidia driver if it exists)

Hello! I recently tried NextDNS and noticed that is detects my current DNS resolved on the go. I just opened its website and it immediately showed my current resolver: When I tried changing private DNS to Cloudflatein settings it instantly showed my new resolver. But how exactly it works? Does the browser send used DNS server to website? Or it is done somehow via JavaScript? And also: So every website can know what I am using now? Can it be used for fingerprinting?

Hello! I recently faced an issue trying to upload big file to Android tablet. It doesn't detect with MTP so I tried to push it via ADB. But I get this error:

$ adb push myfile /sdcard
adb: error: 65544-byte write failed: Success

How can I fix it? Why is this happening? Storage space is enough:

EDIT: I want to use it for app devlopment, so I need ADB or quick MTP for app installing.

Hello everyone! I know that Linux GUI advanced in last few years but we still lack some good system configuration tools for advanced users or sysadmins. What utilities you miss on Linux? And is there any normal third party alternatives?

Hello! I am on Fedora 40 KDE Edition (Wayland). I have monitor with two supported refresh rates (60, 50 Hz). How can I set custom refresh rate? I know, on Windows you can use CRU.

Hello! Halt on Linux is disabled for average user by default. It will try to request sudo/root password and if fails returns:

sasha@fedora:~$ systemctl halt
Call to Halt failed: Access denied

How can I make same behavior for poweroff action? I know it is possible somehow via PolicyKit rulle

Hello! I have a very old PC with intel i915 graphics, which doesn't correctly display KDE and shows a lot of bugs. I know it is possible to switch to software acceleration in X server. On NVdia I can pass nouveau.noaccel=1 to kernel. So how can I disable hardware acceleration here? Maybe this is possible via Xorg config?

Hello! I need to create a VM and passthrought some host USB port to it. Sadly libvirt doesn't support QEMU built-in feature to use -hostport argument (which was added 10 years ago...). I tried to add custom arguments to domain (qemu:commandline) but this didn't work. When I just run qemu-system-x86_64 -device host-usb,hostbus=X,hostport=Y -usb everything works well. It seems like libvirt restricts some QEMU actions. How can I fix this? OS: Debian 12

I installed WireGuard on my host and set this configuration /etc/wireguard/wg0.conf:

I also cannot connect to host via ssh. How to fix this issue?

Upd. Fixed my changing server WireGuard IP to 10.0.1.1. 10.0.0.1 was already taken
