Updating ubuntu 11 04 to 11 10
Some system programs like apt-get will only run properly when some swap space is present (due to 256 MB not being enough RAM).Some images (such as those from Linaro.org) do not come with a swap partition or any swap space allocated.Zulu Open JDK 12, 11, 8 or 7 builds for Windows, mac OS and Linux can be downloaded from this page.On Linux there are binaries available as DEB, RPM and gz (64bit).
Both the DEB / RPM packages and the repositories packages update the Java alternatives in order to make Zulu Open JDK default.
The following commands will create a 1 GB file, limit access only to root, format it as swap and then make it available to the OS: sudo mkdir -p /var/cache/swap/ sudo dd if=/dev/zero of=/var/cache/swap/swapfile bs=1M count=1024 sudo chmod 0600 /var/cache/swap/swapfile sudo mkswap /var/cache/swap/swapfile sudo swapon /var/cache/swap/swapfile To verify that the swapfile is accessilble as swap to the OS, run "top" or "htop" at a console.
It is relatively easy to configure a Wi-Fi card from the command line.
Repositories are also available, for all Linux distributions mentioned above minus Fedora (it didn't work for me on Fedora 29) and Alpine Linux.
So why use the Zulu Open JDK builds instead of Oracle Java or Open JDK?
