[Pkg-privacy-maintainers] Bug#814190: tails-installer: tails installer fails to authentication

[Kenichiro MATOHARA]

Package: tails-installer
Version: 4.4.7+dfsg-1
Severity: normal

Dear Maintainer,

I have been using the "awesome wm".
"Mod4 + r" in entering the "tails-installer-launcher" and run.
Press the "Install Tails" button and press the "OK" button from. It will be for a while to an error.

```
Installing bootloader...
Synchronizing data on disk...
Unmounting mounted filesystems on '/dev/sdb1'
There was a problem executing the following command: `/usr/bin/pkexec /usr/bin/syslinux  -d syslinux /dev/sdb1`.
A more detailed error log has been written to '/tmp/tails-installer-mU_Zx2'.
Tails installation failed!
There was a problem executing the following command: `/usr/bin/pkexec /usr/bin/syslinux  -d syslinux /dev/sdb1`.
A more detailed error log has been written to '/tmp/tails-installer-mU_Zx2'.
```

The following error in the file had been recorded.
All recordings here -> http://paste.debian.net/379225/

```
/usr/bin/pkexec /usr/bin/syslinux  -d syslinux /dev/sdb1
Error creating textual authentication agent: Error opening current controlling terminal for the process (`/dev/tty'): No such device or address
```

Then I ran in the command line. Then, authentication in the command line is required. But it will fail.

```
==== AUTHENTICATING FOR org.freedesktop.policykit.exec ===
Authentication is needed to run `/usr/bin/syslinux' as the super user

```

I used the "gksudo" as the workaround.

```
$ gksudo tails-installer-launcher
```
