 Ubuntu has a mechanism, that is, the installed network card (NIC) will be renamed to another name when the system is booted. Although there is no difference in using it, it is just a little unaccustomed. After booting, we can observe the dmesg log as follows

dmesg | grep rename

You can see that the following network cards eth0 and eth1 have been renamed to ens160 and ens192:

[1.341871] vmxnet3 0000:03:00.0 ens160: renamed from eth0

[1.362582] vmxnet3 0000:0b:00.0 ens192: renamed from eth1

The method of closing is very simple, that is, edit the /etc/default/grub file and change the following parameters:

GRUB_CMDLINE_LINUX="net.ifnames=0 biosdevname=0"

Update grub.cfg with the following command

sudo update-grub

change interface configure

/etc/network/interfaces

error message : configparser.InterpolationSyntaxError: '%' must be followed by '%' or '(', found: "%)']/following::android.widget.EditText"

 In general analysis, the last sentence is the key point: When reading the configuration file config.ini, there are % caused by   Solution one: Most likely configparser is reading the literal "%" sign in the string. The '%' symbol is used for string interpolation (substitution). If you want to use a literal "%", you can escape it with another "%". For example, use "100%%" to mean "100%" in configuration variables read by configparser. Solution two: Change from cf= configparser.ConfigParser() to ： cf = configparser.RawConfigParser()

1 .  Error message : File "tarfile.py", line 2155, in makefile with bltn_open(targetpath, "wb") as target:  OSError: [Errno 22] Invalid argument:  This looks like a windows problem as colons in filenames are reserved characters in Windows. We don't like the idea of renaming the actual file for the sake of supporting in Windows. We will look into alternatives and track this as an enhancement separately.  2.  Edit tarfile.py :  You should add a line in 2155  # targetpath_s = targetpath.replace(':','-')
