Nagios Support Forum

Tried to upgrade to the latest and greatest this morning, looking forward to SSO improvements - I errored out with the following (RHEL): Anyone else see this?

Hi Will,

It looks like libcurl-devel package isn't installed. For an EL based system run the following as root and then retry the upgrade.
For a Debian or Ubuntu system you'll want to run the following (as root) and retry the upgrade.
Thanks and have a great rest of you day,
Keith

Yep. Had the same issue 2026R1.1 -> 2026R1.2.

Doing the libcurl-devel install fixed it. Not sure if this was mentioned in the email blasts or release notes about the new version.

I'm all set!! Thank you both!
