msys2 environment is totally broken

[askondro]

Since some days (last update I think) the msys2 environment is totally broken.

When I open the console, for example msys64.bat:

askon@DESKTOP-BT8UGJK MINGW64 /usr/bin $ which pacman /usr/bin/pacman

askon@DESKTOP-BT8UGJK MINGW64 /usr/bin $ cd /usr/bin/

askon@DESKTOP-BT8UGJK MINGW64 /usr/bin $ ls -l

askon@DESKTOP-BT8UGJK MINGW64 /usr/bin $

pacman -Syu fails with:

askon@DESKTOP-BT8UGJK MSYS /usr/bin $ pacman -Syu error: GPGME error: Invalid crypto engine error: GPGME error: Invalid crypto engine error: GPGME error: Invalid crypto engine :: Synchronising package databases... mingw32 228.1 KiB 292K/s 00:01 [#############################################] 100% mingw32.sig 96.0 B 93.8K/s 00:00 [#############################################] 100% error: GPGME error: Invalid crypto engine error: failed to update mingw32 (invalid or corrupted database (PGP signature)) mingw64 227.1 KiB 331K/s 00:01 [#############################################] 100% mingw64.sig 96.0 B 0.00B/s 00:00 [#############################################] 100% error: GPGME error: Invalid crypto engine error: failed to update mingw64 (invalid or corrupted database (PGP signature)) msys 128.4 KiB 533K/s 00:00 [#############################################] 100% msys.sig 96.0 B 0.00B/s 00:00 [#############################################] 100% error: GPGME error: Invalid crypto engine error: failed to update msys (invalid or corrupted database (PGP signature)) error: failed to synchronise any databases error: failed to init transaction (invalid or corrupted database (PGP signature))

Maybe you can solve it by reading the nice write-up by @Elieux in issue https://github.com/Alexpux/MSYS2-packages/issues/393.

I've tried that. Deleting /etc/pacman.d/gnupg

but pacman-key --init returns nothing:

askon@DESKTOP-BT8UGJK MINGW64 /etc/pacman.d $ pacman-key --init

askon@DESKTOP-BT8UGJK MINGW64 /etc/pacman.d $

and what I find really strange is that I can't list files with "ls -l"..

Does pacman -Qqe work?

[askondro]

seems so:

Ok, one approach to investigate further is to rename your C:\msys64 (assuming that's where it is) to C:\msys64.broken, or generally follow the instructions at https://sourceforge.net/p/msys2/wiki/MSYS2%20re-installation to setup a new installation (be careful to cleanup the junk from /c/packages.txt though), then, install mingw-w64-x86_64-meld3 to compare the differences between the files and folders.

[mingwandroid]

.. if your new installation works after that, then great, but we'd quite like to get to the bottom of this too of course.

Ok, I installed the new environment as instructed on https://sourceforge.net/p/msys2/wiki/MSYS2%20re-installation. Now it works. But after comparing the old msys and the new, how do I export the diff from meld?

[mingwandroid]

Well, to be honest, meld hasn't worked in MSYS2 properly until about a week ago, so I've been using some proprietary software called Beyond Compare 4 in the meantime.

There's guides at other places for using meld (mine is in a broken state due to development work I'm doing). Regardless, doing a normal diff with diff /c/msys64.broken /c/msys64 and pasting the results here would be useful.

[askondro]

the diff output is in the attachment. diff.txt

I've been having a similar problem while running MSYS2 with ConEmu. I was able to resolve it as described at https://github.com/Alexpux/MSYS2-packages/issues/393#issuecomment-299669754
