unuzip with Python 3.8.12 on FreeBSD #2

Open grahamperrin opened 2 years ago

grahamperrin commented 2 years ago

Hi, must I install Python 2 for unuzip to work here?

% pwd
/tmp/0.6.0
% /usr/home/grahamperrin/dev/unuzip/unuzip -v ./system.uzip system.ufs
env: python2: No such file or directory
% python /usr/home/grahamperrin/dev/unuzip/unuzip -v ./system.uzip system.ufs
  File "/usr/home/grahamperrin/dev/unuzip/unuzip", line 41
    print "Error: can't open input file: %s" % e
          ^
SyntaxError: Missing parentheses in call to 'print'. Did you mean print("Error: can't open input file: %s" % e)?
% cd /usr/home/grahamperrin/dev/unuzip
% python unuzip /tmp/0.6.0/system.uzip /tmp/0.6.0/system.ufs
  File "unuzip", line 41
    print "Error: can't open input file: %s" % e

The answer seems to be yes … unfortunately I seem to have problematic .uzip files: 

% python2 /usr/home/grahamperrin/dev/unuzip/unuzip /tmp/0.6.0/system.uzip /tmp/0.6.0/system.ufs
Error: file is not UZIP

… I seem to have problematic .uzip files: …

From https://github.com/helloSystem/hello/discussions/229#discussioncomment-1565485, might this explain the error above?

… we don't really have an ISO9660 filesystem on that uzip, but zfs, and the embedded script can't handle that. …
