如何列出通过 安装的应用程序snap？

lz@vm:$ snap help
The snap command lets you install, configure, refresh and remove snaps.
Snaps are packages that work across many different Linux distributions,
enabling secure delivery and operation of the latest apps and utilities.

Usage: snap <command> [<options>...]

Commonly used commands can be classified as follows:

         Basics: find, info, install, remove, list
        ...more: refresh, revert, switch, disable, enable, create-cohort
        History: changes, tasks, abort, watch
        Daemons: services, start, stop, restart, logs
    Permissions: connections, interface, connect, disconnect
  Configuration: get, set, unset, wait
    App Aliases: alias, aliases, unalias, prefer
        Account: login, logout, whoami
      Snapshots: saved, save, check-snapshot, restore, forget
         Device: model, reboot, recovery
      ... Other: warnings, okay, known, ack, version
    Development: download, pack, run, try

这里没有列出快照

usb 3.0 设备对我来说从来没有在 virt-manager 上工作过。我在主机和来宾上都运行 Ubuntu 20.04，并且只有 2.0 重定向有效。当我执行 3.0 时，它根本不会出现在 lsusb 上的客户机上，也不会出现在磁盘上（例如闪存驱动器）

我正在使用“重定向 USB 设备”选项，而 virt-manager 是 2.2.1

我试过这个：https ://www.dell.com/support/kbdoc/pt-br/000131486/atualizar-o-bios-da-dell-em-um-ambiente-linux-ou-ubuntu在我的戴尔 XPS 13 9310. 我将U盘格式化为FAT32并复制了.exe文件，但是当我进入bios更新选项时却找不到U盘。我尝试了很多选项，在启动时按 F12 或 F2 等。

我也知道它可以通过更新管理器进行更新，但我在我的软件更新程序中没有看到 BIOS 更新

根据https://wiki.gentoo.org/wiki/Linux_firmware，

Linux 固件是与 Linux 内核一起分发的软件包，其中包含某些硬件设备的部分或全部功能所必需的固件二进制 blob。这些二进制 blob 通常是专有的，因为一些硬件制造商不会发布构建固件本身所需的源代码。

例如，我的蓝牙 pcie 设备需要linux-firmware/qca/htbtfw20.tlv. 这是内核驱动程序吗？为什么是格式.tlv，为什么有些是.bin？通常内核驱动程序是 ELF 可执行文件。

刚刚在我全新的 XPS 13 上安装了 Ubuntu 20.04。蓝牙处于活动状态，它找不到任何东西。有一次它找到了“音频设备”和“未知”，但我什至无法点击。

我尝试bluetoothctl了power on,scan on等等，但它什么也找不到。

我什至不知道我的戴尔使用哪种蓝牙设备，因为它不会出现在 lspci 或 lsusb 上：

我5.10.0-051000rc6-lowlatency之所以选择是因为 ubuntu 20.04 附带的那个在睡眠和其他方面存在问题。

我如何知道我正在使用哪个蓝牙设备？

PS：我也没有wifi，好像驱动Network controller: Qualcomm Device 1101 (rev 01)还没准备好。

我尝试了ubuntu 20.10，但安装时出错，尝试了很多次。但我猜这个问题与内核有关。

刚买了新的戴尔 XPS 13 9300 并尝试安装 Ubuntu 24.04.1。Wifi 既不能使用蓝牙，但我现在只需要 wifi。这是wifi卡：

000:55:00.0 Network controller: Qualcomm Device 1101 (rev 01)
    Subsystem: Bigfoot Networks, Inc. Device a501

不管怎样，刚刚发现Ubuntu 20.04 Killer AX500s DBS 驱动程序支持他们说对这个 wifi 卡的支持落在 5.9 上。我安装了 5.9.10：

lz@dell:~$ uname -r
5.9.10-050910-lowlatency

而且还是没有wifi。

在互联网上没有找到关于这个设备的任何信息，在 linux 内核上也没有。https://github.com/torvalds/linux/tree/master/drivers/net/wireless哪里是 qualcomm 或 bigfoot？

这个线程看起来很有希望：https ://github.com/kvalo/ath11k-firmware/issues/4

我知道这里：https ://medium.com/@tomas.heiskanen/dell-xps-15-9500-wifi-on-ubuntu-20-04-d5f1c218e78a有一种方法可以通过编译从 git 安装它，但我从随机的地方安装东西不舒服。

那么有没有办法让它与最新的内核一起工作？

更新：

也试过

lz@dell:~$ uname -r
5.10.0-051000rc5-lowlatency

这是最新的可能。没有成功。

出了点问题，我只想恢复 vm-orwell4-* 容器。至少从中复制一些文件。我对 lvm Thinpool 一无所知。

我试过了

我在 dockerized ubuntu 20 中并尝试运行以下命令，但出现此错误：

sudo ip tuntap add dev tun0 mode tun user `id -un`

open: No such file or directory

试过这个：https ://stackoverflow.com/questions/32924094/ip-tuntap-command-cant-open-tun但它没有用。有谁知道发生了什么？我已经安装了iproute2。缺了点什么？我是 root 并尝试过有无sudo

我跟着https://www.digitalocean.com/community/tutorials/how-to-install-and-configure-vnc-on-ubuntu-20-04放了

xrdb $HOME/.Xresources
startxfce4 &

进入我的.vnc/startup，我可以成功登录 VNC 并使用 nautilus 和其他应用程序，但没有最大化/关闭按钮，最重要的是我无法打开终端。我在扩展坞上单击它，没有任何反应

我也试过把这个：

gnome-panel &
gnome-settings-daemon &
metacity &
gnome-terminal &
nautilus &

我可以成功登录并看到 nautilus 打开，但使用它打开终端没有任何结果，而且我也没有看到除了 nautilus 之外的其他东西（没有可点击的图标）

我最好在 VNC 上使用 gnome，但我不能让两者都工作

这是安装 Rust 的命令：

curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh

做什么|？

我认为 curl 从此链接下载了一个 .sh 文件，并 sh 以某种方式执行它。它是如何工作的？它在我的 Dockerfile 中不起作用，我需要传递-y给它.sh，但我不知道如何。

我关注了 https://mathiashueber.com/windows-virtual-machine-gpu-passthrough-ubuntu/。但是，只有一件事我没有遵循：我离开了 noveau 而不是官方驱动程序，因为如果我按照它说的那样做，当我重新启动时，我只会看到黑屏。而且我想在主机上使用 noveau 而不是专有且可能不安全的驱动程序。

我在技嘉 B450m 主板上安装了 Ryzen 7 2700X。我有一个 GTX 1060，我想把它放在 VM 中，还有一个 GT 750 在主机中使用。

您可以看到我的 GTX1060 在第 15 组中，以及其他我不关心的东西，它们也可以进入 VM。以 USB 控制器为例。

所以我有 10de:2184 (GTX 1060) 和 10de:1aeb (GTX Audio)。我需要保存第 15 组中其他事物的 ID吗？我要尝试处理所有这些，所以我保存了 10de:1aec (USB) 和 10de:1aed (Serial BUS)

和

options kvm ignore_msrs=1

我高亮了第 15 组中的设备。只有 NVIDIA GTX 1060 被使用vfio-pci，其他内核模块正在使用其他设备。这是问题的根源吗？为了通过 GTX，我必须通过第 15 组中的所有内容，但是其他驱动程序正在使用这些其他东西，而不是vfio-pci.

请看一下

请确保 iommu_group 中的所有设备都绑定到它们的 vfio 总线驱动程序

这证实了我的想法vfio-pci，即使我明确对他们说，并非所有设备都可以使用。

我认为他在这部分是这样做的，但对于 nvidia 驱动程序：

为了在 nvidia 驱动程序之前更改加载顺序以支持 vfio_pci，请通过 sudo nano /etc/modprobe.d/nvidia.conf 在 modprobe.d 文件夹中创建一个文件并添加以下行：

softdep nouveau pre: vfio-pci softdep nvidia pre: vfio-pci softdep nvidia* pre: vfio-pci

除了 noveau 有没有办法做同样的事情？

我在运行最新的 raspbian 的树莓派零上安装了 docker

curl -sSL https://get.docker.com | sh

和码头工人组成

sudo pip install docker-compose

当我在树莓中运行 docker-compose 时：

sudo docker-compose up
ERROR: Couldn't connect to Docker daemon at http+docker://localhost - is it running?

If it's at a non-standard location, specify the URL with the DOCKER_HOST environment variable.

当我这样做时sudo dockerd：

sudo dockerd
Segmentation fault

由于分段错误，docker 守护程序似乎无法正常工作。我应该怎么办？

路径/media/external存在并且是空的。如果我这样做，smbclient //192.168.0.3/Public我可以完美地看到这些文件。

怎么了？这似乎是一个本地错误，因为该错误是即时的
