Cannot install pglogical

Question

I cannot install pglogical. I'm fallowing this tutorial: https://docs.aws.amazon.com/dms/latest/sbs/chap-manageddatabases.postgresql-rds-postgresql-full-load-pglogical.html#chap-manageddatabases.postgresql-rds-postgresql-full-load-pglogical-replication

And part about pglogical installation has two steps (I'm using postgres 10.4):

curl https://access.2ndquadrant.com/api/repository/dl/default/release/10/rpm | bash
yum install postgresql10-pglogical

I'm getting an error though:

Loaded plugins: extras_suggestions, langpacks, priorities, update-motd
https://dl.2ndquadrant.com/default/release/rpm/packages/amzn/2/x86_64/10/repodata/repomd.xml: [Errno 14] HTTPS Error 404 - Not Found
Trying other mirror.
 One of the configured repositories failed (2ndQuadrant packages (PG10) for 2 - x86_64),
 and yum doesn't have enough cached data to continue. At this point the only
 safe thing yum can do is fail. There are a few ways to work "fix" this:
 1. Contact the upstream for the repository and get them to fix the problem.
 2. Reconfigure the baseurl/etc. for the repository, to point to a working
 upstream. This is most often useful if you are using a newer
 distribution release than is supported by the repository (and the
 packages for the previous distribution release still work).
 3. Run the command with the repository temporarily disabled
 yum --disablerepo=2ndquadrant-dl-default-release-pg10 ...
 4. Disable the repository permanently, so yum won't use it by default. Yum
 will then just ignore the repository until you permanently enable it
 again or use --enablerepo for temporary usage:
 yum-config-manager --disable 2ndquadrant-dl-default-release-pg10
 or
 subscription-manager repos --disable=2ndquadrant-dl-default-release-pg10
 5. Configure the failing repository to be skipped, if it is unavailable.
 Note that yum will try to contact the repo. when it runs most commands,
 so will have to try and fail each time (and thus. yum will be be much
 slower). If it is a very temporary problem though, this is often a nice
 compromise:
 yum-config-manager --save --setopt=2ndquadrant-dl-default-release-pg10.skip_if_unavailable=true
failure: repodata/repomd.xml from 2ndquadrant-dl-default-release-pg10: [Errno 256] No more mirrors to try.

How can I install it?

• user7070613: 1) How did you install your Postgres server? 2) 2ndQuadrant got bought by EDB so I'm guessing the repos changed.
• Laurenz Albe: The tutorial is probably out of date.
• Murakami: Postgres was installed before on the server. Hard to tel how it was installed
• user7070613: Assuming it was installed from packages use yum to list installed packages and see where the Postgres ones came from.
