MSYS2 won't install

c.posingies · February 1, 2023, 3:07pm

My OS is Windows version is 22H2 (25284.1000). And MSYS2 won’t install. I know that you guys aren’t responsible for MSYS2, but perhaps some of you have encountered the same problem and know a solution! =)

At 50%, I get a message. Since I am a German, this translation might be not so correct: (Message Box)

"Error while installing component com.msys2.root: Execution failed (Unexpected exit code: 254): “C:/msys64\usr\bin\bash.exe --login -c exit”

Tried “Repeat”, but didn’t work. “Ignore” leads to this:

(Console window “MSYS2 UCRT64 Shell” opens)

Content:

Error: Could not fork child process: Resource temporarily not available (-1). DLL rebasing may be required; see 'rebaseall / rebase --help".

Any ideas?

No expert here, but … sure you got the latest and greatest installer ?

https://github.com/msys2/msys2-installer/releases/download/2023-01-27/msys2-x86_64-20230127.exe

and followed the rules:

Installation Folder (short ASCII-only path on a NTFS volume, no accents, no spaces, no symlinks, no subst or network drives, no FAT).

Be sure:

You have admin rights (required to install into C:\msys64 folder).
Disable (during install) your firewall.
Don’t use backslash ** but slash / instead, for paths.

When installed, allow rules are required for .exeS (executables who need connection, like git.exe etc) in your firewall.

Ohmer · February 1, 2023, 3:16pm

Interesting…

(I have downloaded mine from www.msys2.org couple of week ago, also previous versions)

Ohmer · February 1, 2023, 3:20pm

@Jens.Peter.Nielsen msys64 is a valid folder name (I have used D:\msys64)

Surely OP have both folder rights & firewall blockings.

Jens.Peter.Nielsen · February 1, 2023, 3:24pm

I didn’t read properly - it’s right there “C:/msys64\usr\bin\bash.exe --login -c exit”

c.posingies · February 1, 2023, 3:26pm

Yes, of course. No folder with the same name, firewall deactivated, executed the installer as administrator.

Ohmer · February 1, 2023, 3:27pm

Ah yep… perhaps msys2 doesn’t like slashes and backslashes!

Slashes / are working, I’m always using cd /d/RackDev/plugins/Ohmer (as example) since four years.

Also: this Unix-like terminal is case sensitive!

Perhaps try running the msys installer from powershell with "--verbose"

Are you running a third-party anti-virus program, or just using the built-in Defender?

Also, when you run the installer, try and run it by right-clicking on it and select “Run as administrator”.

Caecos · February 2, 2023, 1:11pm

You need to uninstall fisrt MSYS2, after look if the folder is still on your PC and delete it. Then restart your PC and finally install a fresh MSYS2 with administrator rigth… it should works…

jackokring · February 2, 2023, 1:17pm

It has been a long time since I used MSYS2 (64-bit as 32-bit had issues with allocation of memory at the time), maybe it will migrate to WSL in the future, but today? @Caecos says right. If there are still issues, then something very strange is going on.
