Removing a preinstalled app creates user registry directory with wrong ownership

[Paweł Stołowski]

After installing latest image #52, applications fail to install properly (via click scope); download manager's log gives error like this one:

I0528 07:35:48.809278 4281 process.cpp:89] Fatal error: /home/phablet/.local/share/ubuntu-download-manager/Downloads/com.ubuntu.developer.arnaudober.lightoff_0.1.2_all.click failed to install.

The image was installed with 'ubuntu-device-flash --channel=devel-proposed'

Status changed to 'Confirmed' because the bug affects multiple users.

[Colin Watson (cjwatson)]

/opt/click.ubuntu.com/.click/users/phablet is owned by the user clickpkg, which is wrong. I wonder how it ended up this way ...

[Colin Watson (cjwatson)]

We're not seeing this any more after wiping the contents of /opt/click.ubuntu.com/ (including the hidden .click subdirectory) and installing apps again, so this must have been a problem with some prior image; I have no idea what as click didn't change at all in the relevant time period. If this reoccurs with clean userdata then feel free to reopen.

[Colin Watson (cjwatson)]

We've tracked this down. It happens if the first thing you do to apps with clean userdata is to remove a preinstalled app.

This bug was fixed in the package click - 0.4.24

---------------
click (0.4.24) utopic; urgency=medium

  [ Loïc Minier ]
  * Add 14.10 framework in places where all frameworks are listed.

  [ Colin Watson ]
  * Copy the pw_uid and pw_gid members from getpwnam's return value and
    cache those separately, since getpwnam returns a pointer to a static
    buffer so just caching its return value is not useful (LP: #1323998).
  * Handle the renaming of upstart-app-launch to ubuntu-app-launch: we now
    cope with both old and new names.
