Hi, 

I try to access to jobs works in order to solve an email problem (https://community.openproject.com/topics/6429), but here is the responses of my commands.

I tried to install the missing gem manually, but then it asked me to install another, and then another, etc.

Do you know what could be the problem ?

Thanks
