# SageTex, sage, version conflict?

Hello to everyone,

I am trying to use sagetex in my ubuntu18.094 machine. I use the file from this manual. I call my file Test.tex

PdfLatex does its job. I have a `Test.sagetex.sage`

file in my folder. When I run, at the same folder, from a terminal `sage Test.sagetex.sage`

I get the following error

`Traceback (most recent call last):`

`File "Test.sagetex.sage.py", line 9, in <module>`

`_st_ = sagetex.SageTeXProcessor('Test', version='2015/08/26 v3.0-92d9f7a', version_check=True)`

`File "... Programs/sage-8.1/local/lib/python2.7/site-packages/sagetex.py", line 76, in __init__`

`raise VersionError(errstr)`

`sagetex.VersionError: versions of .sty and .py files do not match.`

`Test.sagetex.sage was generated by sagetex.sty version "2015/08/26 v3.0-92d9f7a", but`

`is being processed by sagetex.py version "2019/01/09 v3.2".`

`Please make sure that TeX is using the sagetex.sty`

`from your current version of Sage; see...`

I built sage from the source code, at some point, then I upgraded with `sage update`

. I now have sage 8.8 but still a folder `sage-8.1`

I installed sagetex from the repos.

Anyone a suggestion?

Thanks!
