Installation

Reinstallation

https://github.com/msys2/msys2/wiki/MSYS2-reinstallation

Updating packages

1. Run pacman -Syuu. Follow the instructions.

2. Modify pacman config

pacman colors

sed -i "s/#Color/Color/g" /etc/pacman.conf

pacman mirrors in china(option)

sed -i "1iServer = http://mirrors.ustc.edu.cn/msys2/mingw/i686" /etc/pacman.d/mirrorlist.mingw32 && \
  sed -i "1iServer = http://mirrors.ustc.edu.cn/msys2/mingw/x86_64" /etc/pacman.d/mirrorlist.mingw64 && \
  sed -i "1iServer = http://mirrors.ustc.edu.cn/msys2/msys/\$arch" /etc/pacman.d/mirrorlist.msys

3. Repeat Run pacman -Syuu until it says there are no packages to update.

4. Finally you can do an update of the remaining packages by issuing: pacman -Suu

ConEmu: How to call msys2 as tab?

Install custom packages

pacman -S ccache coreutils gcc gnu-netcat iperf3 lftp make man-db man-pages-posix nano openssh p7zip python python3-pip rsync screenfetch unrar unzip upx vim whois winpty zip

git

git for msys

pacman -S git git-extra

git for windows proper

https://github.com/valtron/llvm-stuff/wiki/Set-up-Windows-dev-environment-with-MSYS2
https://github.com/git-for-windows/git/wiki/Install-inside-MSYS2-proper

Open an MSYS2 terminal.

Edit /etc/pacman.conf and just before [mingw32], add the git-for-windows packages repository:
and optionally also the MINGW-only repository for the opposite architecture (i.e. MINGW32 for 64-bit SDK):

sed -i "/^\[mingw32\]/i\[git-for-windows]\nServer = https://wingit.blob.core.windows.net/x86-64\n" /etc/pacman.conf && \
  sed -i "/^\[mingw32\]/i\[git-for-windows-mingw32]\nServer = https://wingit.blob.core.windows.net/i686\n" /etc/pacman.conf

Authorize signing key (this step may have to be repeated occasionally until https://github.com/msys2/msys2/issues/62 is fixed)

curl -fsSL https://raw.githubusercontent.com/git-for-windows/build-extra/master/git-for-windows-keyring/git-for-windows.gpg | pacman-key --add - && pacman-key --lsign-key 1A9F3986

Then synchronize new repository

pacboy update

This updates msys2-runtime and therefore will ask you to close the window (not just exit the pacman process). Don't panic, simply close all currently open MSYS2 shells and MSYS2 programs. Once all are closed, start a new terminal again.

Then synchronize again (updating the non-core part of the packages):

pacboy update

And finally install the Git/cURL packages:

pacboy sync git:x git-doc-html:x git-doc-man:x git-extra: curl:x

Finally, check that everything went well by doing git --version in a MINGW64 shell and it should output something like git version 2.18.1.windows.1 (or newer).

ZSH

Modify msys2 profile to fix SHELL & soft link

sed -i "/^  profile_d zsh/a\  SHELL=\"\$(which zsh)\"" /etc/profile && \
  sed -i '$a\\nexport MSYS=\"winsymlinks:lnk\"' /etc/profile

Install zsh

pacman -S zsh

Install oh-my-zsh

sh -c "$(curl -fsSL https://raw.githubusercontent.com/robbyrussell/oh-my-zsh/master/tools/install.sh)"

Run zsh as default shell

tee -a ~/.bashrc <<-'EOF'

# Launch Zsh 
if [[ "${ZSH_VERSION:-unset}" = "unset" ]]; then
  export SHELL=/bin/zsh
  exec zsh
fi
EOF
