hi！everyone
I'm having some troubles with my environment。I try to make ls1046ardb，failed。message shows 'python-pip' have be replace by 'python3-pip'. I searched the directary found nothing.the following is the messages:
bt021@LAPTOP-C7GHPEGD:/media/OK10xx-linux-fs$ ./build_1046_C2.sh
installing python-pip ..
Reading package lists... Done
Building dependency tree
Reading state information... Done
Package python-pip is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source
However the following packages replace it:
python3-pip

E: Package 'python-pip' has no installation candidate
cp: cannot stat '/media/OK10xx-linux-fs/flexbuild/build/images/*': No such file or directory

bt021@LAPTOP-C7GHPEGD:/media/OK10xx-linux-fs$ sudo grep -r python-pip ./*

ubuntu 20.4.2LTS in windows10 linux-subsystem

Thanks all

I have solved the problem by change  'python-pip' to 'python3-pin' in "dependent_pkg=..." in flexbuild/tools/flex-builder

Please execute the following command manually.

$ sudo apt-get install python3-pip

In addition, we recommend the customer to use LSDK 20.12 release by NXP, which is executing in ubuntu 18.04.
