Dpkg: error processing package openlitespeed

[dsoneil]

When I try to upgrade OLS 1.6.18 to any version (1.6.19, 1.6.20 or 1.7.9) they all fail, though reverting back to 1.6.18 works fine. I've tried the usual dpkg autoclean, dependency check, dpkg-reconfigure -a, apt remove and reinstall etc. but no luck.

This is the error on Ubuntu 18.04 and this server has been on OLS for 3 years with zero issues to this point. Any suggestions?

This seems to have resolved, somehow. The only thing I did was:

apt-mark hold openlitespeed
apt update && upgrade

and then:

dpkg -i openlitespeed_1.7.9-2+bionic_amd64.deb

And now it runs fine.
