Recently switched to LMDE and I just tried opening the Firewall Configurator and it’s visible for a second or two and then disappears.
I found a thread on the Linux Mint forum that addressed a problem of a missing Firewall app from the GUI list. I ran the following command out of curiosity and I don’t know what to do with resulting information to fix my problem:
gd@red1:~$ sudo gufw
[sudo] password for gd:
/usr/bin/gufw: line 2: [: =: unary operator expected
ls: cannot access ‘/usr/lib/python*/site-packages/gufw/gufw.py’: No such file or directory
No provider of eglCreateImage found. Requires one of:
EGL 15
/usr/bin/gufw-pkexec: line 10: 2220 Aborted (core dumped) python3 ${LOCATIONS[${i}]} $1
gd@red1:~$
There is no easy way, and it may turn out to be impossibly difficult.
What you have to do for a package not available in the package system is start from the source code and make your own port by compiling the source code. You need a knowledge of the language it is written in, plus you will have to use tools like automake, configure and make. Porting is a lot of work.
It would be far easier to install LMDE6, or there may be a method to upgrade LMDE5 to LMDE6…
Thanks Neville. I found a few sources talking about using “backporting” but the suggested command lines didn’t work for me. The example was for Debian Stretch, not LMDE elsie, so I decided to stop there.
