When I ran Software
Updater recently on my 32-bit Ubuntu 14.04 computer it advised me a new version--16.04--was available. After I upgraded everything ran slower. Researching the problem I discovered the computer is in fact a 64-bit machine. I tried a clean install of 64-bit Ubuntu and found 16.04 was too slow with just 1GB of RAM. I installed 64-bit Ubuntu 14.04, changed swappiness to 10, and tried to install OpenCPN
. I ran the following commands in Terminal:
sudo apt-get install software-properties-common
sudo add-apt-repository ppa:bdbcat/opencpn
sudo apt-get update
sudo apt-get install opencpn
The computer came back with
The following packages have unmet dependencies:
opencpn : Depends: opencpn-tcdata but it is not installable
Depends: opencpn-gshhs-low but it is not installable
Recommends: opencpn-doc but it is not installable
Recommends: opencpn-gshhs-crude but it is not installable
Recommends: opencpn-gshhs-intermediate but it is not installable
Recommends: opencpn-gshhs-high but it is not installable
Recommends: opencpn-gshhs-full but it is not installable
E: Unable to correct problems, you have held broken packages.
I changed the repository to opencpn/opencpn, tried again, and got the same result.
How can I fix this?
