Comment 1 for bug 1988853

Running Kubuntu 22.04.1 LTS, I do *not* have this issue; gufw(8) v22.04.0 starts up properly.

I find the initial output line in the above odd:

    /bin/gufw: line 2: [: too many arguments

1st, gufw is in /usr/bin, not /bin (this *may* be a copy-paste mistake?).

2nd, Line 2 of /usr/bin/gufw does not (directly) contain any "["s:

   2.1$ $ nl -ba /usr/bin/gufw
     1 #!/bin/bash
     2 c_user=$(whoami)
     3 pkexec gufw-pkexec $c_user
   2.2$ file $(which whoami)
   /usr/bin/whoami: ELF 64-bit LSB pie executable, x86-64, version 1 (SYSV), dynamically linked, interpreter /lib64/ld-linux-x86-64.so.2, BuildID[sha1]=a18184f5d26fce82fe5ccf842d3cf7b9c729030f, for GNU/Linux 3.2.0, stripped

What happens if you run gufw using the bash(1) shell's -x option? I get:

   2.3$ $ bash -x $(which gufw)
   ++ whoami
   + c_user=USER
   + pkexec gufw-pkexec USER
   Error executing command as another user: Not authorized

   This incident has been reported.

where USER is my username. The "not authorized" is because I cancelled rather than enter my password (for this test, for other tests I entered the password and gufw itself started entirely as expected).
