Debian 9: synaptic package manager won't launch from command line

Every time I enter this line:

sudo pkexec synaptic

The synaptic package manager opens, but always followed by this error message:

E: Could not open file - open (2: No such file or directory)
E: _cache->open() failed, please report.

If I close the error box, synaptic will simultaneously close with it. How do I fix this bug and finally launch synaptic?

@Henrik, I just ran

 sudo apt update

Maybe I should re-install debian? There doesn't seem to be anyway around this.

I had never heard of pkexec before, but a quick look at the man page suggets to me that it's rather redundant in your command. I've never cared for synaptic, so I don't know if the problem might be synaptic-specific or if your package database has been destroyed. My suggestion is that you try to run sudo apt update and show us the complete input+output, maybe that will tell us something that allows us to help you. Whether there's a way around it depends a lot on what has happened.

@roaima There are fixes for it in the different versions of ubuntu and mint, but there's nothing for it in debian 9. The closest I could find was for debian squeeze/wheezy (bugs.debian.org/cgi-bin/bugreport.cgi?bug=708294), but the info is outdated because there appears to be no synaptic.conf file in root.
