VirtualBox running Ubuntu 20 Notes
Sometimes trying to boot into Ubuntu 20 from VirtualBox just results in a black screen with blinking cursor. The last known version of VirtualBox to work was a "test" version, VirtualBox-6.1-6.1.27_146688_test_el7-1.x86_64.rpm but now it fails.
Need to install, test. Migrate Unifi controller to it.
- After following these steps and booting into new kernel, machine would not start
- Booted into old kernel, and ran an update for new packages. New kernel was downloaded and installed.
- Had a new kernel not been available, I suspect reinstalling the original kernel that was failing would have fixed the problem
- Install postfix and choose "Internet site"
- Accept suggested FQDN
- Don't add another user for /etc/aliases (root is already there)
- For comma-separated list of domains, accept defaults
- Accept defaults for everything else, such as synchronous mail, network blocks, etc.
- Follow rest of instructions
- Send test message
