ESS install fails on Ubuntu 18.04

Question

I had previously installed and used Emacs 25.2.2 and ESS 17.11 on Ubuntu 18.04 (Bionic Beaver). While attempting to update to the latest version of ESS, the ESS install script appears to have failed (see terminal output below).

I tried removing (with --purge) and then re-installing both ESS and Emacs 25, but this did not solve the problem.

Does anyone have a solution to this problem?

Bill Venables encountered the same problem and posted it on github as follows:

"An automatic upgrade to ess_17.11-3 on Ubuntu 16.04 has failed, killing ess. The installation script failed with error code 1, without much further information that I can see. This is for Emacs 24. The result was no working ess functionality at all on Emacs.

Purging ess_17.11-3 and manually re-installing ess_17.11-2 worked fine, though.

The same problem with the same killing effect also happened on Ubuntu 18.04 LTS (bionic) with Emacs 25. I have yet to check if re-installing ess_17.11-2 works in that case, but I suspect it shall."

Apparently the bug in the install script has been reported to the r-sig-debian list.

In the meantime, one solution to the problem is to purge ess_17.11-3 and then to manually reinstall ess 17.11-2 from its deb file. This worked for me using Emacs 25.2.2 on Ubuntu 18.04.
