Hi Kazu, I faced with the same error recently. In my case, I decided to use previous version of RDKit in Google Colab as follows.
conda install -q -y -c conda-forge rdkit==2020.03.6 I hope it is helpful for you.

ImportError: /usr/lib/x86_64-linux-gnu/libstdc++.so.6: version `GLIBCXX_3.4.26' not found When I checked with strings /usr/lib/x86_64-linux-gnu/libstdc++.so.6 | grep GLIBCXX, the result was as follows. GLIBCXX_3.4 GLIBCXX_3.4.1 % GLIBCXX_3.4.25 GLIBCXX_DEBUG_MESSAGE_LENGTH So I executed the following: %%bash add-apt-repository ppa:ubuntu-toolchain-r/test -y apt-get update apt-get install gcc-4.9 apt-get upgrade libstdc++6 Again, when I checked with strings /usr/lib/x86_64-linux-gnu/libstdc++.so.6 | grep GLIBCXX, the result was as follows. GLIBCXX_3.4 GLIBCXX_3.4.1 % GLIBCXX_3.4.26 GLIBCXX_3.4.27 GLIBCXX_3.4.28 GLIBCXX_DEBUG_MESSAGE_LENGTH However, I still get the same error when importing RDKit, although GLIBCXX_3.4.26 is installed. ImportError: /usr/lib/x86_64-linux-gnu/libstdc++.so.6: version `GLIBCXX_3.4.26' not found Currently, I cannot use RDKit. I would be grateful if you could give me a hint as to how to solve it.
