For some reason I decided to upgrade setuptools. The so-called package plan that popped up when I ran conda install -c anaconda setuptools was as follows:
The following packages will be downloaded:
package | build
---------------------------|-----------------
certifi-2019.3.9 | py37_0 155 KB anaconda
pip-19.1.1 | py37_0 1.8 MB anaconda
python-3.7.2 | h8c8aaf0_10 17.7 MB anaconda
setuptools-41.0.1 | py37_0 680 KB anaconda
wheel-0.33.4 | py37_0 57 KB anaconda
wincertstore-0.2 | py37_0 13 KB anaconda
------------------------------------------------------------
Total: 20.4 MB
The following NEW packages will be INSTALLED:
pip anaconda/win-64::pip-19.1.1-py37_0
The following packages will be UPDATED:
certifi 2018.11.29-py36_0 --> 2019.3.9-py37_0
python pkgs/main::python-3.6.4-h6538335_1 --> anaconda::python-3.7.2-h8c8aaf0_10
setuptools pkgs/main::setuptools-38.4.0-py36_0 --> anaconda::setuptools-41.0.1-py37_0
wheel pkgs/main::wheel-0.30.0-py36h6c3ec14_1 --> anaconda::wheel-0.33.4-py37_0
The following packages will be SUPERSEDED by a higher-priority channel:
wincertstore pkgs/main::wincertstore-0.2-py36h7fe5~ --> anaconda::wincertstore-0.2-py37_0
However the upgrade broke other parts of my code which are really needed and cannot be updated. Hence I decide to roll back to the previous state. The most recent revisions from conda list --revisions are:
2019-02-12 15:10:38 (rev 12)
bzip2 {1.0.6 (conda-forge) -> 1.0.6 (anaconda)}
ca-certificates {2018.03.07 -> 2019.1.23 (anaconda)}
certifi {2018.11.29 -> 2018.11.29 (anaconda)}
conda {4.5.12 -> 4.6.2 (anaconda)}
nbconvert {5.3.1 -> 5.4.0 (anaconda)}
openssl {1.1.1a -> 1.1.1 (anaconda)}
snappy {1.1.7 (conda-forge) -> 1.1.7 (anaconda)}
vc {14.1 -> 14.1 (anaconda)}
vs2015_runtime {14.15.26706 -> 15.5.2 (anaconda)}
yaml {0.1.7 (conda-forge) -> 0.1.7 (anaconda)}
zlib {1.2.11 (conda-forge) -> 1.2.11 (anaconda)}
+defusedxml-0.5.0 (anaconda)
2019-05-17 16:52:29 (rev 13)
certifi {2018.11.29 (anaconda) -> 2019.3.9 (anaconda)}
pip {9.0.1 -> 19.1.1 (anaconda)}
python {3.6.4 -> 3.7.2 (anaconda)}
setuptools {38.4.0 -> 41.0.1 (anaconda)}
wheel {0.30.0 -> 0.33.4 (anaconda)}
wincertstore {0.2 -> 0.2 (anaconda)}
The problem now is that when I do conda install --revision 12 I get the following error:
PackagesNotFoundError: The following packages are missing from the target environment:
- anaconda::certifi==2018.11.29=py36_0
Any ideas how to do the rollback please?
Many thanks

I agree with J_H, the best is to keep your environment.yml produced with conda env export > environment.yml in your code versioning system (Git). Then in case of problem you can delete your environment and recreate it (but not with conda env update) with conda env create -f environment.yml.

Just in case someone bumps into this, facing a similar situation, this what I did and to be fair, it is not actually a rollback. It also appears that my conda environment was really messed-up the upgrade I mentioning in my original post because when I did conda update conda I received the following error:
>conda update conda
Collecting package metadata: done
Solving environment: | WARNING
conda.common.logic:get_sat_solver_cls(289): Could not run SAT solver through interface "pycosat".

WARNING conda.common.logic:get_sat_solver_cls(289): Could not run SAT solver through interface "pysat".failed
My numpy was also broken and who knows what else....
I followed the steps desribed by Kale Franz at this link: https://github.com/conda/conda/issues/7714#issuecomment-417553149
For the sake of completeness, I am attaching a screenshot of his answer below:
Running the command that Kale suggests in his post, I got a really long list of the packages that are causing inconsistencies. I was a really long list, I am just pasting below the very first few lines:
Collecting package metadata: done
Solving environment: \
The environment is inconsistent, please check the package plan carefully
The following packages are causing the inconsistency:
- defaults/win-64::alabaster==0.7.10=py36hcd07829_0
- defaults/win-64::anaconda-client==1.6.9=py36_0
- defaults/win-64::anaconda==custom=py36h363777c_0
- defaults/win-64::anaconda-project==0.8.2=py36hfad2e28_0
- defaults/win-64::asn1crypto==0.24.0=py36_0
- defaults/win-64::astroid==1.6.1=py36_0
.... (A lot more that I am not pasting here) ....
And after the list ended the message continued as follows:
