The Linux experice

About a week ago I setup Ubuntu as my primary OS on an old machine. It is my first time trying a unix based OS (previously windows). It has been ok, but it seems like every time I try to install something I run into problems. The app has the wrong permissions or I don't have the right packages or I need to change port settings ect... I was expecting a learning curve but I wanted to know if this is something I should expect to be a long term issue or if I will aquire the skills to side step stuff like this over time?

Update* I got it working. Last night I reinstalled it and figured it out. Two issues. On initial install I failed to update one of the packages needed. I also assigned the service to a group without the required permissions. On reinstall I rectified both of these issues and it works flawlessly. Thanks all for your help and input (and ignoring typos in the title)!
