# Wrong Version jail If a different version of FreeNAS is running from the version of a jail. For example, the FreeBSD version FreeNAS is based upon is 11.0, but a jail is based on 10.3, the following error can occur when attempting to install something from ports in a jail. > make: "/usr/ports/Mk/bsd.port.mk" line 1177: UNAME\_r (11.0-STABLE) and OSVERSION (1003000) do not agree on major version number There are two solutions to this problem, the non-permanent option is to set an environment variable in the current shell with `setenv UNAME_r 10.3-RELEASE`. The permanent solution is to set the environment variable by editing `/etc/login.conf`, and adding the jail's version. ```shell default:\ :setenv=UNAME_r=10.3-RELEASE:\ ``` Reset the database. ```shell cap_mkdb /etc/login.conf ``` Exit and enter shell and everything should work. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
