Follow these instructions in order to setup CometBFT.
Finally, you should have GLIBC
v2.29 or higher.
MacOS: the system-provided glibc should be recent enough.
Ubuntu 20.04: glibc is installed by default and you don't have to do anything more.
Ubuntu 18.04: glibc has
v2.27 by default which is lower than the required version to run Namada. We recommend to directly install from source or upgrade to Ubuntu 19.04, instead of updating glibc to the required version, since the latter way can be a messy and tedious task. In case updating glibc would interest you, this website (opens in a new tab) gives you the steps to build the package from source.
