Update: Gummi installed with no problem and seems to work. Thanks...
I need to install some sort of TeX editor on Linux Mint (19.1 "Tessa"). The Software Manager kindly offers to install TeXStudio but that fails with a 404. The install script at https://community.linuxmint.com/software/view/texstudio also fails, could not retrieve a few packages. For the heck of it I execute "texstudio" in a terminal window - it says it's not installed but can be installed with sudo apt [something]" - that also fails to retrieve a few packages.
If anyone has an idea how a Linux weenie can install TeXStudio or some other suitable TeX editor that would be fabulous.
