Elasticsearch 7.10.0 not start Ubuntu 20.04

Elastic Stack Elasticsearch

My elasticsearch 7.8.1 on my laptop was automatically updated to 7.10.0. I wanted to roll back to the previous version and now I have messed up. Elasticsearch does not even start successfully.

Anybody knows how to completely clean up and install ES 7.8.1 again? Please help.

What OS are you running?

3

Ubuntu 20.04

4

Did you use the deb or the apt repo?

5

I belive it is apt since I used sudo apt-install

6

Then you can use apt-get remove or purge to remove things, then reinstall.

To purge the old settings and installation: sudo apt-get remove --purge elasticsearch

But I was unable to install 7.8 since the archive is not found. 7.10.0 is fine but I want to use the previous version. Do you have suggestions how to install 7.8?

You can tell apt to install specific versions of a piece of software, you may want to consult the man page for apt.
