Hello Robert, Ubuntu MATE is a community developed version of Ubuntu. Which means that it's maintained by user / developers like you.
You might want to contact the community [1] directly for your issues that you have encountered on MATE (or the Caja package maintainer [2] or even the Caja maintainers upstream [3] [1] https://ubuntu-mate.community/ [2] https://launchpad.net/ubuntu/+source/caja [3] https://tracker.debian.org/pkg/caja -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux-signed in Ubuntu. https://bugs.launchpad.net/bugs/1799019 Title: Linux crashed so severly that I have to reinstall. Status in linux-signed package in Ubuntu: Invalid Bug description: First Google Chrome and Chromium crashed closing all their windows. Then most, but not all, of the VisualWorks windows diappeared. (Unfortunately the System window closed so I could not exit properly). Then the list of open windows at the bottom of the screen disappeared, as did the menu bar at the top. With no menu to shutdown, I had to turn power off. When I tried to reboot I got the Ubuntu symbol and the progress dots underneath. After more than an hour, I got a command line to log in. (Not a terminal window - Ubuntu never started.) I was able to log in but could do nothing since this was a system without MATE or any window GUI. Every time I try to reboot, I get the save progress dots for over an hour and then the terminal mode login prompt. I had to boot from the distribution DVD to make this report before re- installing the system. Please fix your documentation on reporting system crashes. What is "apport" and how do I run it?
