Cydia sub-process/USr/Libexec/Cydia/Cydo error 100

scenario
The new entry test of the company is suspected to have directly deleted the XXX. App folder under the Applications directory, resulting in the disappearance of the app icon on the desktop but not uninstalled in the Cydia installed list.
Repetition steps
Try to uninstall or install any plug-ins
The results of
sub-process /usr/libexec/cydia/cydo returned an error code(100)
The solution
Use iFile to find /usr/libexec/cydia/cydo file on the mobile phone, click I on the right to check the access rights, and change the access rights to
user: sticky, read, write, execute
group: sticky, read, execute
global: read, execute
Other methods that have been tried do not work
Delete all files under the DPKG/Updates folder
conclusion
In order to avoid this kind of problem, it is necessary not to misoperate and do not interrupt the installation and uninstallation process. Xiaobai had better use Cydia to operate and do not try to delete files directly.

CentOS 7 installation error: Cannot find a valid baseurl for repo: base/7/x86_6

First, report the wrong situation
When using the yum command, you cannot parse the yum source, and an error occurs:

Second, report the cause of the error
The machine cannot parse the yum source, for three reasons:
(1) The machine can not access the Internet! Please check the network configuration to make sure that you can surf the Internet and then look at the second situation. A simple point is ping a public network IP, such as ping 114.114.114.114 if ping does not work, is not on the network. If you can ping it, that would be the second case.

(2) DNS configuration problem! Nslookup www.baidu.com
nslookup www.baidu.com
nslookup www.baidu.com
nslookup www.baidu.com
nslookup www.baidu.com
nslookup www.baidu.com

(3) The machine can access the Internet, DNS configuration has also been configured, but still cannot resolve yum source, then you can change to a yum source and try again.

Three, can’t access the Internet solution
(1) Check the network card name and enter the command:

(2) Start to modify the network information configuration file, open the configuration file, and enter the command:

vi /etc/sysconfig/network-scripts/ifcfg-Name of the network card
e.g：vi /etc/sysconfig/network-scripts/ifcfg-ens33

(3) Change ONBOOT=no to ONBOOT=yes

4. DNS configuration error solution
(1) This problem is caused by yum’s inability to resolve the domain name corresponding to the remote packet management library even though it has been connected to the Internet during the process of package installation. Therefore, we only need to add the IP address corresponding to DNS to the network configuration. Open the configuration file and enter the command:

vi /etc/sysconfig/network-scripts/ifcfg-Name

(2) Append DNS at the end of the file:

DNS1=8.8.8.8
DNS2=4.2.2.2

(3) Restart the network and enter the command:

ifup Name
e.g：ifup ens33

Solve the problem of VC 6.0 fatal error C1033: cannot open program database’.\debug\vc60.pdb’

VC++6.0 compiled a few times, suddenly appeared

The always open a program database… debug\vc60.pdb

then compile has been the error information…

There are several sayings on the Internet:

The
The
1. File properties, change to archive line.

The
The
The 2.
Only need to modify the directory, because my original directory path contains Chinese, not recognized, all changed to English. This doesn’t happen on the Chinese version of XP.

3. Clean all, and then rebuild all!

The 4. It could be a memory leak in your program that causes a dead process!

I tried, looks like the above said method are not make for me,

then, he asked the elder brother of the ACM, they say just restart the VC6.0 with respect to OK, ha ha, problem is solved!!!!!! Well, then another big brother said he just had to shut down the project and turn it on. Well, I haven’t tried that yet…

alas, the power is off… I wanted to paste that article on VC6.0 detecting memory leaks later…

other: on CSDN

PDB is Program the meaning of the Database, recorded some information about the Program and debug the related information.
in the Project Settings can set whether to use PDB, by default is selected. If selected, this file will be automatically generated when recompiling.

other people say the solution is:

Edit-> If Preferences find: repositories is empty, change it to stdmod

The second method to modify the path is the solution to the problem I encountered, but it is not the optimal one. In fact, if you are careful, you will find that the compilation fails because of the Chinese scrambled code caused by the Chinese path, so solving the scrambled code problem should solve the problem.

The solution, of course, is to modify the format of the language’s advanced options.

Hanyu Formats and Language for Non-Unicode Programs choose Chinese.

After following the steps in the red box above

To Build – first & gt; The Clean, and then Build – & gt; Rebuild All

That solves the problem. This is much more convenient than changing the path, especially for Chinese projects where changing the name will make you cry

Declare my IDE environment:

Windows8.1 with UPDATE, English, Enterprise, VC6.0 SP6, the official original mirror file + official download SP6 patch, many castrated version of VC6.0 sometimes appear some puzzling mistakes, especially the Chinese version of VC6.0, even VC assistant VA are not used, as a developer, if fear of English, then I still advised you to change line.

Recently updated when cydia to the sub – process/usr/libexec/cydia cydo returned anerror code (2) of the scarlet letter is how to return a responsibility?

[Errno 8] nodename nor servname provided, or not known

Using python’s own standard DNS library,
Frequent errors
[Errno 8] nodename nor servname provided, or not known
Check some articles, DNS resolution is a problem with a lot of concurrency.
Solution: Instead of using Python’s DNS resolution standard library, use gEvent’s built-in DNS resolution module to replace the standard library.
(When the following patch_all() is implemented, GEvent will help us replace a series of standard libraries.)

from gevent import monkey;monkey.patch_all()

At this point, [Errno 8] Nodename Nor Servname provided, or Not known issues only happen the first time DNS is resolved, only once.

Adb error: more than one device/emulator error handling

During the development of projects, it is often necessary to use ADB command for debugging. When the mobile phone is connected to the computer and ready to use adb shell command, the following error occurs
jason@zhanghailongdeMacBook-Pro ~ % adb shell
error: more than one device/emulator
According to the error prompt, the error is caused by the connection of multiple devices on the computer, and adb shell command does not know which one to operate, so the error is exploded. Check with ADB Devices:

jason@zhanghailongdeMacBook-Pro ~ % adb devices

List of devices attached
LGUS9982d76c740 device
192.168.201.7:5555 device
Sure enough, several devices appear. If you want to debug for a particular device, you need to specify the name of the device for adb command, such as debugging for device 2F54EE0:
jason@zhanghailongdeMacBook-Pro ~ % adb -s LGUS9982d76c740 shell
Joan:/$
In this way, it is possible to debug normally. If there is still a problem with the above method, the following scheme is recommended:
// Kill adb Server first :adb kill-server
// Restart ADB Server: ADB Start-up – Server

Error Code: S1023 when installing DirectX SDK

When installing DXSDK_Jun10, the following Error occurs, Error Code:S1023

Reason for error:
Also, I continued to distribute Microsoft Visual C++ 2010 Redistributable after I installed the updated Microsoft Visual C++ 2010 Redistributable and opened the program and function control panel on my computer. While DXSDK_Jun installed “Microsoft
Visual C++ 2010 x86 redistributable-1010.0.30319″, the version was lower than the installed version of this machine, so s1023 error occurred in the installation.
Solutions:
Uninstall the higher version of “Microsoft Visual C++ 2010 x86 redistributable-1010.0.40219” and reinstall it.
