Is it safe to install Texmaker from Ubuntu Software Center? It is outdated and a newer version is available from the Texmaker projekt website, but I really do not want to install software from "outside the software center". The Texmaker in the software center is in the universe repo. Does somebody know if texmaker opens any ports or accesses internet if I just open the installed program?
I believe a quick look at the changelog might help you (no security issues mentioned...). You can find this here: http://www.xm1math.net/texmaker/log.html. To answer your question: as far as I know TexMaker does not open ports.
If this motivates you to install the latest version anyway:
- Download TexMaker (http://www.xm1math.net/texmaker/download.html#linux)
- Remove previous versions:
sudo apt-get purge texmaker(in a terminal)
- Install TexMaker
sudo dpkg -i ~/Downloads/texmaker_ubuntu_*.deb(if the deb file you've downloaded is still in the 'Downloads' folder).
