Install and update LaTeX macro package in Ubuntu/Mint

Generally, there are not many built-in macro packages for software such as texlive installed in Linux, and many macro packages have been installed several years ago, in this way, it is often possible to compile the tex files on the Internet in the near future ~ Of course, you can put the macro package on the Internet directly to the tex file directory, but it is too DT to copy N files each time... The process of installing and updating the macro package is as follows. I use my own Mint and texlive as an example.
 
1. First, find the directory where the default macro package is located. Google can check that there are two
 
/Usr/share/texmf/tex/latex
/Usr/share/texmf-texlive/tex/latex
 
2. if you install a new macro package, you can directly push the compressed file of the macro package into the first directory and decompress it directly. Note that the unzipped file may contain installation instructions, follow the installation instructions. If you update a macro package, you can find it in the second directory, rename the original macro package to *-backup, and decompress the downloaded macro package to compress the file, if installation instructions are available, follow the instructions.
 
3. Re-mark the macro package and execute it on the terminal.
 
# Texhash
 
 
4. Log off/Log in is complete.
