The error you’re encountering is related to a missing version of the GNU C++ Library (libstdc++) on your system - a lib which upgraded Cursor IDE was compiled with.
You can see your GLIBCXX versions executing:
strings /usr/lib/x86_64-linux-gnu/libstdc++.so.6 | grep GLIBCXX
I have Ubuntu 20.04 and what fixed the issue for me was:
sudo add-apt-repository ppa:ubuntu-toolchain-r/test
sudo apt-get update
sudo apt-get upgrade
An original solution here: ppa - GLIBCXX_3.4.20 not found, how to fix this error? - Ask Ubuntu
