libreadline.so.6 issue in ubuntu 18.04

[7segv]

I upgrade my system to 18.04 and when trying to run yosys I get issue below:

yosys: error while loading shared libraries: libreadline.so.6: cannot open shared object file: No such file or directory

I try to uninstall libreadline-dev with

sudo apt-get purge libreadline-dev

and install the libreadline.6 with

sudo apt-get install libreadline6-dev

but the system install the latest version (libreadline-dev_7.0-3) again:

Note, selecting 'libreadline-dev' instead of 'libreadline6-dev'

Is there a way to fix the issue?

Did you rebuild Yosys after updating Ubuntu?

Closing as issues seems to be abandoned by OP. Simply rebuilding Yosys, as suggested by daveshah1, should fix the problem.
