Command line: PSCP – I C: \ “code \” jerrylaunchpad \ “aliyun.ppk% 1 root@SAP-DIS :/home/Jerry
From the discussion of stack overflow, we know that due to root@SAP-DIS As a result, root is the user name and sap-dis is the host name. Replace the host name with the IP address of the host, and the error disappears. You can copy it:

SSL handshake failed: SSL error: key usage violation in certificate has been detected appears when downloading the source code of SVN linked with HTTPS on Linux server
The reason for the error is that the certificate used by windows is not recognized by Linux
Add the following registry value to the windows registry: (mine is 64 bit)
for 32-bit system: (run regedit – > Find the following registry key – > Add a value of type DWORD)
[HKEY_LOCAL_MACHINE\SOFTWARE\VisualSVN\VisualSVN Server]
"CreateGnuTLSCompatibleCertificate"=dword:00000001for 64-bit system:
[HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\VisualSVN\VisualSVN Server]
"CreateGnuTLSCompatibleCertificate"=dword:00000001StartVisualSVN Server Manager.(Open virsualSVN server）
Go toAction | Properties | Certificate.
ClickChange certificate…
Select Create new self-signed cetificate.
Next all.
If you run svn again on Linux, you will be prompted with a warning that the certificate generator is not trusted, just select Accept Permanently.
Recently, in the development process, I want to delete a jar package on the server, but the name of the jar package is in parentheses
at the beginning, I deleted it like this:
rm -f HIBIKI_API(1).jarBut I got the following sentence:
bash: syntax error near unexpected token `(' Then I googled it and found that after linux5.0, you can’t use brackets. At this time, you need to translate. There are two ways of translation
1.rm -f HIBIKI_API\(1\).jar
2.rm -f "HIBIKI_API(1).jar"In this way, the translation will be OK
Problem Description: today on Linux system through wgethttp://downloads.souceforge.net/tcl/tcl8.6.1-src.tar.gz After downloading resources from the Internet, the following error is generated through tar – zxvftcl8.6.1-src.tar.gz
gzip: stdin: not in gzip format
tar: Child returned status 1
tar: Error is not recoverable: exiting now
(PS: later, after checking, it was found that there was a spelling problem in SourceForge, but Baidu found that not only spelling errors would lead to the above problems, but if the link failed or the jump link was a simple web page, it would also affect the download, so it was necessary to record the solution process.)
Solution process:
1. After checking http://downloads.souceforge.net/tcl/tcl8.6.1-src.tar.gz The website learned that there was a problem with the link jump
2. Search tcl8.6.1-src.tar.gz to enter TCL official website
3. Copy http://downloads.sourceforge.net/tcl/tcl8.6.1-src.tar.gz The website can be used as the download link
4. Or click the above web address, automatically jump to the following page, wait for 5 seconds, and automatically jump out of the download prompt window, copy the pop-up web address:
https://nchc.dl.sourceforge.net/project/tcl/Tcl/8.6.1/tcl8.6.1-src.tar.gz It can also be used as a download link
5. After installation, unzip the. Tar.gz package tar – zxvf tcl8.6.1-src.tar.gz
6. Switch Directory: CD tcl8.6.1/unix
7../configure// execute the configure file
8. Make// compile
9. Make install// install
10. – zxvf is the tar command decompression syntax:
-X unpack. Tar file
-V display details
-F specifies the decompression file
-Z decompression
Example: $tar – zxvf dir1.tar.gz
J’ava deployed to tomcat, and found a problem. The verification code of our login appeared garbled code, and characters
However, on the windows server, or our local development environment, there is no such phenomenon
Why
Looking at the source code, we found a piece of code:
new Font(“Times New Roman”, 0, 18)
The original windows operating system has its own default font, namely Times New Roman
Our Linux system, taking CentOS 7.3 as an example, does not have this font. After all, our Linux system does not have a graphical operation interface, so it does not have its own default font
Therefore, we need to install the font on the Linux system. The process is as follows:
1. First, open our terminal. The default path of font is: usr/share/fonts
CD in
2. Create a new path (folder), MKDIR “Times New Roman”
Why double quotes?Because we need to develop a good habit, if there are no double quotation marks, we will create three new folders, that is, three paths time New Roman. We can’t create paths with spaces
3. Then upload all times New Roman Fonts in fonts folder of our local windows folder to this path. Take the local win7 system as an example, after uploading, we need to execute three commands in this path in turn, as follows:
mkfontscale
mkfontdir
fc-cache -fv
There is a problem. Our CentOS system does not have these commands by default. At this time, we need to install the following commands online. The commands are as follows:
yum install mkfontscale
After installation, confirm in turn
4. Restart our Tomcat
cd ../bin/; sh startup.sh; cd ../logs/; tail -f catalina.out
Just press enter
Note that all the above operations on fonts must be completed under the root permission
5. After the restart, refresh our verification code again. As expected, it changed from random characters back to our letters and numbers

System information:
Operating system: Ubuntu 14.04 lts
OS
Desktop environment: Gnome
System default language: English
Problem Description:
After sudo apt get install IBus Pinyin, pressing the shortcut key Ctrl + space cannot switch between Chinese and English. Even if Chinese pinyin is activated in input method settings, it still has no effect
Solution:
First, other input methods can be used
Second, open the terminal, input IBus list engine, press enter, and print out all the input engine information of IBus. Check whether there is a language: Chinese Pinyin – Pinyin engine. If there is, enter IBus engine pinyin to switch to Chinese Pinyin input. However, the input method icon is not displayed in the notification bar. Enter IBus engine xkb:us : eng can switch to English input again. Every time you log in to the system or restart IBus, the default is xkb:us ::eng。

It should be related to the type of hard disk. Please refer to here
sudo apt-get install exfat-fuseThis method can solve this problem in TX2 and workstation, but Lenovo notebook encountered this problem, but it is not easy to use this method, I do not know what the reason is, there is no in-depth study
Error occurred

You might want to run 'apt-get -f install' to correct these:
The following packages have unmet dependencies:
linux-image-generic : Depends: linux-image-4.4.0-165-generic but it is not going to be installed or
linux-image-unsigned-4.4.0-165-generic but it is not going to be installed
linux-modules-extra-4.4.0-154-generic : Depends: linux-image-4.4.0-154-generic but it is not going to be installed or
linux-image-unsigned-4.4.0-154-generic but it is not going to be installed
linux-modules-extra-4.4.0-165-generic : Depends: linux-image-4.4.0-165-generic but it is not going to be installed or
linux-image-unsigned-4.4.0-165-generic but it is not going to be installed
E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).It seems to have something to do with the kernel version of Linux
