I just can't seem to get my
head around
Linux. Any help here MUCH appreciated!
My main nav
laptop runs
OpenCPN v4 with Navigatrix, and seems to
work fine right now.
My backup machine has
Linux Mint 17 installed, and I just don't seem able to get
OpenCPN updated from v3 to v4.
I think I have to add a repository, that I thought I'd got right, only now when running the Synaptic Package Manager, I get the following error message:
E: Type ‘ppa
![02_stick out tongue](https://www.cruisersforum.com/images/smilies/tongue.gif)
encpn/opencpn’ is not known on line 1 in source list /etc/apt/sources.list.d/additional-repositories.list
E: The list of sources could not be read.
Go to the repository dialogue to correct the problem.
E: _cache->open() failed, please report.
I don't understand what that means.
When I look at the list of PPA's there are two entries for OpenCPN. I'd be most grateful for any help aimed at one who simply cannot get his
head around Linux:-)
