ubuntuone-syncdaemon crashed with OSError in __init__() (symlink on shares)

[Sashin]

When the symlink for ~/Ubuntu One/Shared With Me gets changed to a non-existant file, syncdaemon throws an exception and stops working. Exception from syncdaemon-exceptions.log looks like this:

  File "/usr/lib/ubuntuone-client/ubuntuone-syncdaemon", line 184, in <module>
    main(sys.argv)
  File "/usr/lib/ubuntuone-client/ubuntuone-syncdaemon", line 134, in main
    ignore_files=options.ignore)
  File "/usr/lib/python2.6/dist-packages/ubuntuone/syncdaemon/main.py", line 108, in __init__
    self.vm = volume_manager.VolumeManager(self)
  File "/usr/lib/python2.6/dist-packages/ubuntuone/syncdaemon/volume_manager.py", line 312, in __init__
    os.symlink(self.m.shares_dir, self.m.shares_dir_link)
OSError: [Errno 17] File exists

-----------------------------------------------------------------------

TEST CASE:

From a terminal session, run:

u1sdtool -q
cd ~/Ubuntu\ One
rm Shared\ With\ Me
ln -s foo Shared\ With\ Me
u1sdtool --start

Expected result: Shared With Me symlink points to ~/.local/share/ubuntuone/shares and files in Shared With Me folder are accessible.

If I open ubuntu one nothing happens for a while and I get this error.

Sashin, thanks for your bug report. According to the syncdaemon-exceptions log file, there seems to be a problem accessing the directory: /home/sashin/.local/share/ubuntuone/shares - please could you check the existence and permissions of that directory, and let us know what you find? Thanks.

[Sashin (sashin)]

Yes, this folder exists and it looks like it can only be affected by
root.

[Eric Casteleijn (thisfred)]

Do you remember running anything related to ubuntu one as root, and/or modifying permissions manually which could have caused this? The ubuntu one client does not normally run as root, and hence should not be able to change file permissions like this.

[Joshua Hoover (joshuahoover)]

Hi Sashin, As Eric already stated, Ubuntu One should not be run as root. If you installed or ran Ubuntu One as root, then you will likely have problems like this. If you did not install or run Ubuntu One as root, please let us know and we'll look into it further. Thank you, Joshua

[Lucio Torre (lucio.torre)]

it seems to me that this bug has been hijacked with a new error. As it already has many duplicates assigned and the old error does not have any new information, ill make this bug about the second error, the failing symlink.

[Guillermo Gonzalez (verterok)]

Hi,

Can anyone of the affected by this bug paste the output of:

ls -la ~/Ubuntu\ One/Shared\ With\ Me

Thanks!

[Colin Watson (cjwatson)]

Accepted ubuntuone-client into lucid-proposed, the package will build now and be available in a few hours. Please test and give feedback here. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you in advance!

[Joshua Hoover (joshuahoover)]

Test case passed with 1.2.2-0ubuntu2 proposed installed.

[Martin Pitt (pitti)]

Since it was fixed in trunk a while ago, I assume that maverick's current version (1.3.2) has the fix as well. Closing all the maverick tasks.
