The way snaps work, they are strictly confined with apparmor that prevents access to the host system. There are interfaces that, when connected, allow partial access to some of the host's features, but to my knowledge none of them allow executing random binaries in /usr/bin/.

Indeed, the TexMaths extension uses external programs like /usr/bin/latex, /usr/bin/dvipng, /usr/bin/dvisvgm and the texlive LaTeX packages to produce LaTeX equations in LibreOffice (in Writer, Draw and Impress components). Since the access to /usr from the snap packages is not possible, this breaks TexMaths. I guess there are other extensions that could be affected by this problem. I tested and reproduced the issue in Ubuntu 16.04.3 LTS (64 bits) with the snap package of LibreOffice 5.4.4.2. Here is a link to download and test TexMaths (please note that texlive must be installed before) : http://roland65.free.fr/texmaths/ To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/libreoffice/+bug/1747875/+subscriptions -- Mailing list: https://launchpad.net/~desktop-packages Post to : [email protected] Unsubscribe : https://launchpad.net/~desktop-packages More help : https://help.launchpad.net/ListHelp
