Hi all,
I have a problem with my upgrade of my nodebb installation.

Details of my system:

lsb_release -a     Ubuntu 18.04.6 LTS
node -v            v16.20.2
npm  -v            8.19.4
nvm  -v            0.39.3

I installed nodejs 18 and realized (too late ... ) it will not work with my OS version on my machine.
I uninstalled nodejs 18 and installed 16 through nvm.
And node -v shows, that I am on nodejs v16.20.2

So I don't understand, why I get the error:

node: /lib/x86_64-linux-gnu/libc.so.6: version `GLIBC_2.28' not found (required by node)

When I upgrade my forum, I get the following error:

npm WARN deprecated [email protected]: use nodebb-plugin-emoji instead.

Can somebody please help me, so that I can upgrade my installation?

Thanks,
