You have been subscribed to a public bug: Auctex is a package which allows in particular to preview formulas when typing Latex under Emacs. Under Ubuntu 18.04 LTS this is provided by package auctex. But the previews don't appear.
I have checked on auctex site that this is a known problem of the version of auctec used in Ubuntu, version 11.91-1ubuntu1. So i have removed the auctex package and installed instead the auctex package provided by elpa directly in my home. This one is based on a more recent version 12.1 of auctex. Now previews work OK which confirms that the solution of the bug is to upgrade auctex. ** Affects: auctex (Ubuntu) Importance: Undecided Status: New -- auctex preview doesn't work https://bugs.launchpad.net/bugs/1807600 You received this bug notification because you are a member of Desktop Packages, which is subscribed to auctex in Ubuntu. -- Mailing list: https://launchpad.net/~desktop-packages Post to : desktop-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~desktop-packages More help : https://help.launchpad.net/ListHelp
