Someone have the same issue?

TIA

Noboby has experienced the same issue, nobody have installed recently barman on RHEL7 ?

[Frederic KAPP]

Hello

We are on Redhat v7.8 and we have installed barman 2.9 successfully without issue, so it's not exactly your issue

Which version of python do you have ? Looks like it's 2.7 (as us)

Since barman v2.8 the system requirements are Python 3.4 but because of some obscure dependancies and confusing reasons the required packages are never installed on our environments....

(See http://docs.pgbarman.org/release/2.8/ the "System requirements " section)

We will upgrade soon barman to 2.11, may be we will hit the same issue

Hello 

The sys admin has updated the redhat and it's OK BUT there is a trick regarding the python package: He had to deinstall the python package and install the new one. The barman packages have been moved to a common repository : https://www.postgresql.org/about/news/announcing-common-yum-repository-2027/  

Here are some infos :
