Update issues to 0.7.8.1

[willpower232]

I am unable to update to the latest version. I am running a standard account and get the following error message:

/bin/wslbridge: Exit 1.
wslbridge error: failed to start backend process

If I try 0.7.8, the wsltty window closes immediately on opening but I am able to install 0.7.7.2 and resume usage.

Interestingly, I get the same error if I install 0.7.7.2 as an administrator and run it as my standard user.

Works here.
@rprichard , any idea?

I have the same problem

I don't know what's going wrong. I would guess some kind of permissions issue. I just installed wsltty 0.7.8.1, and it worked fine, with both my ordinary administrator account and a limited account. I then ran wslbridge.exe from an ordinary console running cmd.exe, and that too worked fine:

luser@duck15063:/mnt/c/Users/luser/AppData/Local/wsltty/bin$ exit

C:\Users\luser\AppData\Local\wsltty\bin>

The wsltty installer places the files in the current user's AppData directory, so I'm not sure how to install as an admin and run as a different user. Copy it somewhere public, I guess? Maybe I'll give that a try.

I'm not sure how to install as an admin and run as a different user

I think this refers to running the installer elevated (i.e. "Run as Administrator").

I tried installing 0.7.7.2, running the installer as elevated, then running wsltty normally (non-elevated), and it worked fine.

FWIW, I'm using Windows 10.0.15063.413.

It's also important not to enable the legacy console. (This checkbox must not be checked, because the legacy console is incompatible with the WSL wrapper, bash.exe: https://www.isunshare.com/windows-10/enable-use-legacy-console-for-command-prompt-in-windows-10.html). With 0.7.8.1, though, if it is checked, wsltty displays an error:

/bin/wslbridge: Exit 1.
wslbridge error: failed to start backend process
note: bash.exe output: Unsupported console settings. In order to use this feature the legacy console must be disabled.

I get a more detailed error message:

wslbridge error: failed to start backend process
note: backend error output: /mnt/c/Users/Nicolai/AppData/Local/wsltty/bin/wslbridge-backend: /usr/lib/x86_64-linux-gnu/libstdc++.so.6: version `GLIBCXX_3.4.21' not found (required by /mnt/c/Users/Nicolai/AppData/Local/wsltty/bin/wslbridge-backend)

Upgrading to Ubuntu 16.04.2 LTS fixes it though. I guess this isn't compatible with the older distro.

[rprichard]

I suppose that when I build wslbridge, I need to have the oldest possible WSL environment installed on my machine. That's a pain.

[rprichard]

I released wslbridge 0.2.3, whose binaries are built on Ubuntu 14.04 instead of Ubuntu 16.04. I also started compiling the backend with -static-libgcc and -static-libstdc++, which I don't think it necessary, but maybe it'll be helpful. I believe the binaries in wslbridge-0.2.3-cygwin64.tar.gz are the ones wsltty uses.

[mintty]

Thanks a lot. Released 0.7.8.3. Please recheck.

[willpower232]

I haven't been blessed with the Creators Update yet so my Bash is still Ubuntu 14.04.5

Version 0.7.8.3 works for me

I'm also experiencing the same problem. I had to record my screen using my phone because I had trouble seeing the error message.

wsltty: 1.8.5.2
Windows 10: 1803

The same wsltty version on my other computer, which is running Windows 10 version 1709, works fine without any problems.

[simoncpu]

The exact error is:

wslbridge error: failed to start backend process
note: backend error output: /bin/bash: /mnt/c/Users/Surface: No such file or directory

Hmm, I just realized that the path wslbridge-backend path is incorrect. My user directory (I just used the default) is C:\Users\Surface Pro 4. Issue with spaces in the directory, maybe?

[simoncpu]

I manually ran wslbridge:

C:\Users\Surface Pro 4\AppData\Local\wsltty\bin>wslbridge.exe
wslbridge error: failed to start backend process
note: backend error output: /bin/bash: /mnt/c/Users/Surface: No such file or directory

Oooo.... That issue was solved in latest commit in wslbridge rprichard/wslbridge@47b41be

If you want you may compile that wslbridge frontend. Or @mintty may release apatched version.

[simoncpu]

Awesome, thanks for your help @Biswa96! :)
