I upgraded to 19.04 few weeks ago, however the screen froze mid-upgrade (assuming due to graphics driver glitch, I use a GTX 1070 card, yea I still need to figure out why none of the official drivers work with the card, but that’s for next time). I restarted because the screen practically stopped responding, and followed something like this https://askubuntu.com/a/346795/70531
There are still a lot of random broken things, but I reseted my home directory and started everything from scratch so everything seems to work fine. Except the software center is now complaining SSL handshake error and some error regarding snap store CA unknown.
sudo dpkg-reconfigure -p critical ca-certificates
but that doesn’t seem to change anything. I still get errors whenever I run
jeffrey04@NOBITA-UBUNTU:~$ snap refresh core
error: cannot refresh "core": cannot refresh snap-declaration for "gnome-logs":
x509: certificate signed by unknown authority
There’s nothing much I can find about the error message, and the only place I found that says don’t try to MITM the CA https://bugs.launchpad.net/snappy/+bug/1620755 which is not helpful. What should I do?
