#gcc -v
Found version 4.7.7
but
Installing the above enhanced software requires the gcc5.0 provided with 16.04 Version 4
Solution:
1 sudo update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-5 100 2 sudo update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-4.7 50 3 sudo update-alternatives --install /usr/bin/g++ g++ /usr/bin/g++-5 100 4 sudo update-alternatives --install /usr/bin/g++ g++ /usr/bin/g++-4.7 50 Then Re-install #./autorun.sh Done!
Environment: machine with independent graphics card 2060
After installing Ubuntu 16.04, you can’t enter the graphical interface, and you’re stuck in this interface all the time
Error reported:/dev/sda2: clean******
Solution:
In the current interface, enter the command line mode and execute the following commands (in the command line mode, press Ctrl + Alt + F1 ~ F6, mine is Ctrl + Alt + F1, try it yourself)
1. Uninstall the installed graphics card driver
sudo apt purge nvidia-*
sudo apt autoremove
2. Search for matching driver version
ubuntu-drivers devices
A matching drive will be displayed, such as 430 or 438
3. Installation
Sudo apt get install nvidia-430 (for example, if the matching driver shown above is 430)
4. Reboot and restart
Get the repair file get-pip.py
Access get repair file
Find the download link of the corresponding version file, such as Python 3.5, https://bootstrap.pypa.io/pip/3.5/get-pip.py
Download using WGet, WGet https://bootstrap.pypa.io/pip/3.5/get-pip.py
Execute the file using the corresponding version of python, Python 3.5 get pip. Py

“tpm_tis: A TPM error (6) occurred attempting to read a pcr value”.
Information about TPMhttps://wiki.archlinux.org/index.php/TPM
If you not need TPM, just
echo blacklist tpm_tis > /etc/modprobe.d/tpm_tis.conf (need root)
It worked on my computer. The error gone.
$sudo vim /etc/modprobe.d/tpm_tis.conf
Enter the following: blacklist tpm_tis
Additional options:
just activate the security chip in the bios, that should work, too. similar to whatRikTwrote, on my thinkpad the error message was gone after i enabled the security chip in the bios, changing it frominactivetoactive. so it seems you can get rid of the error message by either activating or disabling the security chip.
First perform:
sudo apt-get install libldap2-dev
sudo apt-get install libsasl2-devThen execute, OK:
pip install python-ldap参考博文内容：
These are the steps to be followed to install python-ldap in Ubuntu. At first,
sudo apt-get install python-ldap
would throw the following error
In file included from Modules/LDAPObject.c:4:0: Modules/common.h:10:20: fatal error: Python.h: No such file or directory compilation terminated. error: command 'gcc' failed with exit status 1
To get past this error, we need to install python-dev package
sudo apt-get install python-dev
After installing that we ll get the following error
In file included from Modules/LDAPObject.c:9:0: Modules/errors.h:8:18: fatal error: lber.h: No such file or directory compilation terminated.
To get past this error, we need to install ldap2-dev package
sudo apt-get install libldap2-dev
After installing that we ll get the following error
Modules/LDAPObject.c:18:18: fatal error: sasl.h: No such file or directory compilation terminated. error: command 'gcc' failed with exit status 1
To get past this error, we need to install libsasl2-dev package
sudo apt-get install libsasl2-dev
After that
sudo apt-get install python-ldap
should install python-ldap without any problems.
First install JDK (Oracle official website), and then check whether the installation is successful
As shown in the figure:
After downloading the Mars version of eclipse, it is found that it cannot be opened normally, and the error message is shown in the following figure:

A Java Runtime Environment (JRE) or Java Development Kit (JDK)
must be available in order to run Eclipse. No Java virtual machine
was found after searching the following locations:
/home/leblancs/Software/eclipse/jre/bin/java
java in your current PATH
After analyzing the error, eclipse did not find JRE, so it reported an error
CD to the installation directory of eclipse, establish a soft connection and connect to JRE,
ln – S/ here is the installation directory of JDK /JRE JRE 
Start eclipse successfully

Error reason: you already have a process bound to HTTP port 80. You can run the command sudo lsof - I: 80 to get the list of processes using this port, and then stop/disable the web server
solution: you can run the command to stop the process using port 80 sudo fuser - K 80/TCP
