wsltty terminal closes as soon as it opens

[Luiscri]

I'm experimenting this type of error. Reading other issues here I launched it with the hold option and it showed this error message:

/bin/wslbridge: Exit 1.
error: 'C:\Users\luisc\AppData\Local\wsltty\bin\wslbridge-backend' backend program is missing

I installed WSL following the instructions of Microsoft official page and did not configure anything else. I'm pretty new to working on Windows, so sorry if I don't understand or know how to do quite simple things.

Did you check if that "C:\Users\luisc\AppData\Local\wsltty\bin\wslbridge-backend" file exists?

[Luiscri]

No it doesn't, it only exists one called wslbridge under the same directory. How can I generate the missing file?

[Biswa96]

Try to run the wsltty installer or the easiest way to extract the backend file from the wsltty installer with 7zip (or equivalent).

[Luiscri]

Running again the installer solves the problem, but after certain time the error appears again.
Now it also says:

note: backend error output: -v: -c: line 0: unexpected EOF while looking for matching `''
-v: -c: line 1: syntax error: unexpected end of file

@Luiscri WSL 2 ?

If you are using Windows 10 insider build fast preview 18945 or greater there is a chance to get that error. Here is the same error occurs with other user rprichard/wslbridge#44 (comment). The workaround is to copy the System32/bash.exe from older insider build. Or use wslbridge2.

wslbridge2 + wsltty ? How to process ?

[Biswa96]

wslbridge2 does not match in wsltty repository right now because there is a command line option (distribution name vs distribution GUID) that does not match. But one can execute wslbridge2 binary in mintty as a regular command.

[OlivierMary]

It's the system used by https://github.com/microsoft/terminal ? I can run on it, but mouse interaction with tmux didn't works

Thanks, using wslbridge2 worked.

I extracted the latest release to the wsltty bin directory and used these .bat to launch the terminals.

@echo off
rem WSL1 distro
C:\Users\cesar\AppData\Local\wsltty\bin\mintty.exe -i "C:\Users\cesar\AppData\Local\wsltty\wsl.ico" --configdir="C:\Users\cesar\AppData\Roaming\wsltty" C:\Users\cesar\AppData\Local\wsltty\bin\wslbridge2.exe -d Ubuntu-16.04

@echo off
rem WSL2 distro
C:\Users\cesar\AppData\Local\wsltty\bin\mintty.exe -i "C:\Users\cesar\AppData\Local\wsltty\wsl.ico" --configdir="C:\Users\cesar\AppData\Roaming\wsltty" C:\Users\cesar\AppData\Local\wsltty\bin\rawpty.exe wsl -d Ubuntu-18.04

Just remember to replace the username.

Thanks. You seem to have edited the comment after first posting and replaced hvpty with rawpty for the WSL 2 case. Note that this will obstruct full transparency of mintty features, only those that are also supported by the MS terminal concept are available. Using hvpty gives you full mintty functionality.

The next mintty release shall dispatch to either wslbridge2 or hvpty automatically when triggered with option --WSL.

[OlivierMary]

For generic .bat

@echo off
rem Start mintty terminal for WSL package Ubuntu-18.04 in current directory
%LOCALAPPDATA%\wsltty\bin\mintty.exe -i "%LOCALAPPDATA%\wsltty\wsl.ico" --configdir="%APPDATA%\wsltty" %LOCALAPPDATA%\wsltty\bin\rawpty.exe wsl -d Ubuntu-18.04

[mintty]

See my previous comment. Using rawpty, you don't really have mintty anymore.
Next wsltty release shall solve all issues.

[AiOO]

Thanks to @cesarga and @OlivierMary's comments, I've succeed to run WSL on mintty. 😻

On the other hand, I think the -d option is not working because default distribution always runs regardless of its value.

[OlivierMary]

Only rawpty work for me, but mouse interactions with tmux does not work....

See my previous comment. Using rawpty, you don't really have mintty anymore.

I just configure font + colors -_-"

@mintty

Using hvpty gives you full mintty functionality.

@echo off
rem WSL2 distro
%LOCALAPPDATA%\wsltty\bin\mintty.exe -i "%LOCALAPPDATA%\wsltty\wsl.ico" --configdir="%APPDATA%\wsltty" %LOCALAPPDATA%\wsltty\bin\hvpty.exe -d Ubuntu-18.04

Right?
Windows 1903 (18980.1). WSL2 works. Mouse/keyboard works. Thanks.

To know what is happening, maybe add -h always to the mintty's argument.

[mintty]

Released 3.0.5 with new gateway.
