Curl error (56) while trying to install Zabbix packages on RHEL 8

  • 772

I followed the instructions here https://www.zabbix.com/download?zabbix=5.4&os_distribution=red_hat_enterprise_linux&os_version=8&db=mysql&ws=apache to install Zabbix 5.4 Mysql/Apache on my RHEL 8 server.

When i tried to install the package with sudo dnf install zabbix-server-mysql (or with yum) , i got this error :

Errors during downloading metadata for repository 'zabbix':
  - Curl error (56): Failure when receiving data from the peer for https://repo.zabbix.com/zabbix/5.4/rhel/8/x86_64/repodata/repomd.xml [Received HTTP code 407 from proxy after CONNECT]
Error: Failed to download metadata for repo 'zabbix': Cannot download repomd.xml: Cannot download repodata/repomd.xml: All mirrors were tried

  • The thing is, if i try curl https://repo.zabbix.com/zabbix/5.4/rhel/8/x86_64/repodata/repomd.xml => i'm able to retrieve content.

  • In the other hand, if i try curl -x http://proxy_user:user_pw@my_proxy:8080 https://repo.zabbix.com/zabbix/5.4/rhel/8/x86_64/repodata/repomd.xml => i'm able to retrieve content too.

Proxy is set system-wide to access internet in /etc/environment => http_proxy="http://proxy_user:user_pw@my_proxy:8080/" https_proxy="http://proxy_user:user_pw@my_proxy:8080/"

every other repo (rhel repo, ansible repo etc...) are currently working, except for ZABBIX.

Did i miss anything in my current configuration ?

Thanks a lot for the help

redhat curl rhel8 zabbix

  1. Ok after some researches i found out that RHEL repos (within /etc/yum.repos.d/) have proxy configured in every repo files. (maybe due to proxy-wide configuration ? i don't know...)

    In my case :

    • i have to disable http_proxy & https_proxy in /etc/environment
    • i let proxy configured into every repos configuration files.

    Then run sudo dnf update and sudo dnf install zabbix-server-mysql and everything runs smoothly ! (#auto-handshakes#)
