How to fix – Apple Calendar can’t save event to Exchange

Refer: https://michaelkummer.com/technology/fix-calendar-cant-save-event-x-exchange/

The Calendar app often gives you three options: Revert to Server, Try Again and Ignore. In some cases, neither option resolves the issue, and the error message keeps coming back, every time Calendar tries to synchronize with the Exchange Server.

The solution involves deleting some cache files and restarting all Calendar processes. In a nutshell, you have to:

The following 3 files were deleted and fixed the problem:

  • Go to ~/Library/Calendars
  • Calendar Cache-wal
  • Calendar Cache-shm
  • Calendar Cache
  • Quit Calendar application (Command + Q)
  • Quit Apple Mail
  • Open Activity Monitor (through Spotlight or Launchpad)
  • Search for “Calendar” and quit all the relevant processes
  • Open Finder and navigate to ~/Library/Calendars
  • Double-check Activity Monitor to make sure no Calendar-related processes are running
  • Delete cache files
  • Relaunch Calendar

Updating Bash profile on Amazon AWS Ubuntu Instance

It looks like we do not have customized .bashrc files on the AWS instance of Ubuntu.  Instead, you can create a customized script to setup your defaults.

Refer: https://serverfault.com/questions/491585/is-there-a-global-bash-profile-for-all-users-on-a-system
Refer: https://bash.cyberciti.biz/guide//etc/profile.d

Updating Sublime / Installing Ubuntu 18.10

Running Sublime from the command line with:
$ subl

In Ubuntu 18.10 out of the box, it was necessary to install the following package because sublime would NOT start.

Refer: https://forum.sublimetext.com/t/solved-ubuntu-18-10-failure-to-launch/39926/3

$ sudo apt-get install libgtk2.0-0

It was throwing the following errors when trying to run the program:

$ /opt/sublime_text/sublime_text
Unable to load libgdk-x11-2.0.so
Unable to load gdk_cairo_create from libgdk-x11-2.0.so

Older Notes of Installation

Sublime was updated via the repository and then downloaded from the site itself.

Just download the file, become root and delete the existing files and copy over them here:

/opt/sublime_text
