Adding this answer partially because it fixed my problem of the same issue and so I can bookmark this question myself. I was able to fix it by doing the following: sudo apt-get install gcc-multilib g++-multilib If you’ve installed a version of gcc / g++ that doesn’t ship by default (such as g++-4.8 on lucid) … Read more
Allow docker container to connect to a local/host postgres database
TL;DR Use 172.17.0.0/16 as IP address range, not 172.17.0.0/32. Don’t use localhost to connect to the PostgreSQL database on your host, but the host’s IP instead.

Make sure PostgreSQL is configured to listen for … Read more

What is makeinfo, and how do I get it?
In (at least) Ubuntu when using bash, it tells you what package you need to install if you type in a command and its not found in your path. My terminal says you need to install ‘texinfo’ package. sudo apt-get install texinfo

How to run cron job every 2 hours? [closed]
Just do: 0 */2 * * * /home/username/test.sh The 0 at the beginning means to run at the 0th minute. (If it were an *, the script would run every minute during every second hour.) Don’t forget, you can check syslog to see if it ever actually ran!
nginx – nginx: [emerg] bind() to [::]:80 failed (98: Address already in use)
I fixed this by running: sudo apachectl stop It turns out apache was running in the background and prevented nginx from starting on the desired port. On Ubuntu, run: sudo /etc/init.d/apache2 stop
