Migrate to Ubuntu

My MacBookPro's hard drive stooped working last week and I managed to recover most of the data from a Time Machine back-up 6 months ago. But I couldn't get the mu4e and mu working. I feed up with googling, trying, and decide to immigrate to Ubuntu. It would save me from a lot of frustrations and time in making my Mac and office PC work the same way.

Ideally, I will built a Ubuntu on Mac which is exactly the same as the one on my office PC, by just copy over everything ¹. As a minimalist, I decided to build the system from scratch and install software one by one so that I can have an better understanding of what are the necessities for me.

In the last few days, I become extra mindful about the what and how I used the Ubuntu system in the office, and realise the things I need can be grouped into three categories:

1. Configuration,
   1. the .ssh folder for the ssh-agent,
   2. the .fonts folder for new fonts,
   3. the .mbsynrc file for sync emails,
   4. the .ledgerrc.
2. Software for
   1. Development: like git, gcc, Emacs, and R.
   2. Writing: org-mode, LaTeX,
   3. Email: mu, mu4e, and mbsync.
   4. Finance: ledger.
3. Personal git repositories
   1. public reposity on GitHub,
   2. private reposities on BitBucket

For 1), since they are small, I can zip up and copy over, or even better, create a git repository so that sync on two machines becomes better easier.

For 2), I need to find the software's package name in the Ubuntu's software repository, and then install all of them by a script. The dependencies should be resolved automatically.

For 3), I need to create a shared folder between the host system and the Ubuntu system, and then copy over the ~/git/ folder.

It really sounds like a plan! I am going to download the Ubuntu installation file now and hopefully the transition will be very smooth.
