When I run lsblk I get the error
lsblk: symbol lookup error: /lib/aarch64-linux-gnu/libsmartcols.so.1: undefined symbol: m�mmove, version GLIBC_2.17
How can I solve that?
Hardware: Raspberry PI 4B
OS: Ubuntu 20.04 LTS (all updates done)
While a little late to help the OP, I ran into a similar problem with a symbol lookup error. So I am posting my solution, so it can help others in the future.
The only way I was able to fix a lookup error with lsblk was to reinstall lsblk. It is not a package you can find in apt, but it is inside util-linux. So since util-linux is already installed, you will have to force the reinstall.
sudo apt install --reinstall util-linux
