Richard Rublev's questions

我尝试在 22.04 上更新

Failed to allocate directory watch: Too many open files

sysctl fs.inotify.max_user_instances
fs.inotify.max_user_instances = 128

应该是什么sysctl fs.inotify样子？

我的服务状态显示

service nfs status
Unit nfs.service could not be found.

我检查了 unix 守护进程

ps aux | grep nfsd
mikigm     12022  0.0  0.0  20452  2636 pts/0    S+   11:03   0:00 grep --color=auto nfsd
ps aux | grep mountd
mikigm     12168  0.0  0.0  20452  2476 pts/0    S+   11:05   0:00 grep --color=auto mountd

和

showmount -e
clnt_create: RPC: Program not registered

然后

systemctl list-unit-files nfs*
UNIT FILE          STATE   VENDOR PRESET
nfs-common.service masked  enabled      
nfs-config.service static  -            
nfs-idmapd.service static  -            
nfs-utils.service  static  -            
nfs-client.target  enabled enabled  

蒙面状态是什么意思？

每次都apt update显示错误

W: GPG error: https://dl.yarnpkg.com/debian stable InRelease: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 23E7166788B63E1E
E: The repository 'https://dl.yarnpkg.com/debian stable InRelease' is not signed.

我试过了

curl -sS https://dl.yarnpkg.com/debian/pubkey.gpg | sudo apt-key add -

gpg: keyblock resource '(null)': General error

使用 y-ppa-manager 我也一样

我为我的 Github 身份验证添加了这个密钥，所以我害怕从列表中删除它。我找不到它

提到的文件看起来像编译的二进制文件（我猜）

我应该删除它吗？

如何检查 gpg 资源并解决这个问题？

我试过 wget

wget -m ftp://miljenko@lw001.usbx.me:11963/Mastering%20Chrome%20Developer%20Tools/
--2021-01-03 13:01:52--  ftp://miljenko@lw001.usbx.me:11963/Mastering%20Chrome%20Developer%20Tools/

Connecting to lw001.usbx.me (lw001.usbx.me)|185.38.14.145|:11963... connected.

然后用 lftp

lftp ftp://miljenko@lw001.usbx.me:11963/
Password: 
cd: Fatal error: Certificate verification: Not trusted (09:0E:0A:43:A8:C2:F7:E2:F6

我的朋友告诉我密码，直到现在一直是一个魅力。

我尝试了 Matigo 的建议

cd: Fatal error: Certificate verification: Not trusted (09:0E:0A:43:A8:C2:F7:A8:F6:F6:F4:E0:00:2C:E8:C7:EC:7E:FE:1A)
mirror: Access failed: 550 /Mastering%20Chrome%20Developer%20Tools: No such file or directory

检测到 1 个错误 Chrome 开发工具

如何解决这个问题？

没有下载。如何指定格式代码？

Youtube-dl 有时有效，有时无效：

youtube-dl https://www.youtube.com/watch?v=62uM1trEf6M
[youtube] 62uM1trEf6M: Downloading webpage
ERROR: No video formats found; please report this issue on https://yt-dl.org/bu

我的 Ubuntu 版本是 20.04。5分钟前，我下载了视频没有任何问题。

有人可以详细说明一下吗？

为什么我有这个错误？

我可以看到 Elements HDD，但它没有安装。

sudo mount -t /dev/sdd1 /media/miki

我有

mount: /media/miki: can't find in /etc/fstab.

我做了mnt1，但现在出现了新的错误

sudo mount -t ntfs /dev/sdd1 /mnt1
$MFTMirr does not match $MFT (record 0).
Failed to mount '/dev/sdd1': Input/output error
NTFS is either inconsistent, or there is a hardware fault, or it's a
SoftRAID/FakeRAID hardware. In the first case run chkdsk /f on Windows
then reboot into Windows twice. The usage of the /f parameter is very
important! If the device is a SoftRAID/FakeRAID then first activate
it and mount a different device under the /dev/mapper/ directory, (e.g.
/dev/mapper/nvidia_eahaabcc1). Please see the 'dmraid' documentation
for more details.

这是什么意思？

我试图安装 qt-5 但我得到了

E: The list of sources could not be read.

如何修复此错误？我试图像这样删除 .list3

 sudo rm /etc/apt/sources.list.d/google-chrome.list:3
rm: cannot remove '/etc/apt/sources.list.d/google-chrome.list:3': No such file or directory

这是我得到的sudo gedit /etc/apt/sources.list.d/google-chrome.list

deb [arch=amd64] http://dl.google.com/linux/chrome/deb/ stable main

有什么建议么？

我正在尝试安装 ParaView CMake

Error at /usr/local/share/cmake-3.6/Modules/FindPackageHandleStandardArgs.cmake:148 (message):
   Could NOT find HDF5 (missing: HDF5_HL_LIBRARIES) (found version "1.8.11")

如何解决这个问题？我在 HDF5 上看到有一些与 FORTRAN 编译相关的错误。有人遇到过类似的问题吗？我在 Ubuntu 14.04 上。

我有一对 png 图像，我想将它们包含在论文中。这是一个例子：

图像下方有一大片空白区域。如何裁剪此图像以摆脱该空白？我在 Ubuntu 14.04 上。我试过了，convert -trim但没有任何改变。

我在 Ubuntu 14.04 上。每次我更新我的比赛时，我都得到了

N: Ignoring file 'libdvdcss.lis' in directory '/etc/apt/sources.list.d/' as it has an invalid filename extension
N: Ignoring file 'libdvdcss.lis' in directory '/etc/apt/sources.list.d/' as it has an invalid filename extension

我从 sources.list.d 给出 ls 输出

getdeb.list                          libdvdcss.list                            videolan-stable-daily-trusty.list.save

libdvdcss.lis                        videolan-stable-daily-trusty.list

当我尝试这个

milenko@milenko-HP-Compaq-6830s:/etc/apt/sources.list.d$ rm libdvdcss.lis
rm: remove write-protected regular file ‘libdvdcss.lis’? yes
rm: cannot remove ‘libdvdcss.lis’: Permission denied

编辑我也做了同样的事情，只是我首先以 root 身份输入。

我买了 Goldentec 网络摄像头。当我进入音量控制时，输入设备我看到内置数字立体声 (IEC958)。我的网络摄像头无法识别吗？如何更改？
