After upgrade ubuntu 16 to 18, I got this error when executing tmux:

tmux: error while loading shared libraries: libevent-2.0.so.5: cannot open shared object file: No such file or directory

and here's result when I execute ldd $(which tmux):

linux-vdso.so.1 (0x00007ffd9878a000)

libutil.so.1 => /lib/x86_64-linux-gnu/libutil.so.1 (0x00007f5588dfc000)

libtinfo.so.5 => /lib/x86_64-linux-gnu/libtinfo.so.5 (0x00007f5588bd2000)

libevent-2.0.so.5 => not found

libresolv.so.2 => /lib/x86_64-linux-gnu/libresolv.so.2 (0x00007f55889b7000)

libc.so.6 => /lib/x86_64-linux-gnu/libc.so.6 (0x00007f55885c6000)

/lib64/ld-linux-x86-64.so.2 (0x00007f5588fff000

I got tmux by following instructions on GitHub. It worked on Ubuntu 16.

$ apt-cache policy tmux

As @guiverc commented - both tmux and libevent are well-packaged on Ubuntu Bionic Beaver 18.04 LTS (and other versions).

You should remove locally-installed tmux with one of the following methods:

Check version of locally-installed tmux:
```
tmux -V # or from `man tmux`
```
Then clone this version from its github repository, compile it again and run
```
sudo make uninstall
```

Simply remove your self-installed tmux with
```
sudo rm $(which tmux)
```
Note: running sudo rm $(which tmux) looks safe because of the fact that even official package do not have shipped other binaries or libraries.

And install package from repository:

sudo apt-get install tmux
