General workarounds

Clearing the package cache

Currently, you must do this if a download error occurs (i.e., a Check Trust error, Package Checksum error, or Download error). You can also do this to clear disk space.

Exit QNX Software Center.
Remove the cache directory (~/.qnx/swupdate/cache).
Restart the software.

Clearing your cached myQNX credentials

If you use the secure storage feature, you may occasionally need to delete and reset the storage record, either because your myQNX credentials have changed or because the storage mechanism remembers the wrong credentials. To reset the secure storage record:

Select Window > Preferences and then in the resulting window, select Security > Secure Storage.
Click the Contents tab, select Default Secure Storage, then click Delete.
When prompted, click Yes to restart the QNX Software Center.
When prompted, enter your myQNX credentials, then click Save password to disk if you want to create a new storage record for the credentials.

The Secure Storage dialog contains other settings but you rarely need to use them. They're provided mostly for troubleshooting and somewhat for use by system administrators and power users.

Installing packages in offline mode

If your QNX Software Center client can't connect to the server, you can perform offline installation. Before trying this, ensure you have:

A baseline (QNX SDP) installation; this also can be installed offline (see instructions referred to in Step 3 below)
A valid and activated QNX SDP license; the activation can be done offline also (see instructions referred to in Step 3 below)

To install packages offline:

Download the necessary packages from the QNX website:
- URL for QNX SDP 7.0 packages — https://www.qnx.com/download/group.html?programid=30107
- URL for QNX SDP 7.1 packages — https://www.qnx.com/download/group.html?programid=51771
Start (or restart) the QNX Software Center client. When it displays a dialog box saying that it can't connect to the server, click Work Offline.
In the QNX Software Center User's Guide, go to the section titled Import packages or package archives from your local filesystem and follow the instructions for importing packages.
Note that you may have to select multiple packages to resolve any interpackage dependencies.

Installing packages offline without QNX Software Center

If you still have installation problems using offline mode but you really need to install some packages, you can manually obtain and unpack them on your development host. To do so:

Obtain the packages by other means (e.g., a QNX contact person). Note that group packages have no payload; you need to obtain all of their children.
On your host, navigate to the root directory of the QNX SDP installation; for example:
```
cd ~/qnx710
```
Untar the package; for example:
```
tar xvf aaa.qpkg
```
Don't add the z option to the tar command.

Performing a complete wipe

The first time you try wiping the QNX products from your host development system, you may want to skip the optional steps (to see if the simpler procedure fixes your problems). If the usability issues persist, you can then try an in-depth wipe by doing all of the steps.

Remove all baseline (QNX SDP) installations by going to the Advanced tab and for each installation:
1. Select it in the top-right dropdown shown next to the gear icon.
2. Click Remove Installation in the bottom right corner.
3. Click OK at the confirmation prompt and wait for QNX Software Center to remove the baseline installation (this can take a couple of minutes).
Deactivate all of your licenses by going to the Licenses tab, selecting all licenses in the list, then clicking Deactivate in the bottom right corner (and Yes at the confirmation).
Exit the software by selecting File > Exit.
Optional: Uninstall QNX Software Center using the uninstaller located in the installation directory, then reinstall the software by downloading the latest version from our website.
Remove the software update directory (~/.qnx/swupdate/).
Optional: Remove the Eclipse secure storage directory (~/.eclipse). The QNX Software Center and QNX Momentics IDE use this for storing passwords and other permanent settings. Note that this directory's location is platform-dependent; to learn its location:
1. Open QNX Software Center and select Window > Preferences.
2. In the left-side navigation, select Security > Secure Storage.
3. Click the Contents tab. The secure storage directory is listed at the bottom.
Optional: Remove any detached installations. An installation of QNX SDP 7.0 or another QNX product is detached if the QNX Software Center doesn't see it. In this case, you must manually uninstall it and remove its folder from the filesystem.
Restart QNX Software Center (if you haven't already) and try reinstalling the baseline product and any packages you need.

Contacting QNX Technical Support

When contacting QNX Technical Support, have the following information ready:

The log file for the latest use session (this is the same file described in the Cannot connect to the server step that talks about the QNX Software Center being out of memory)
What version of QNX Software Center you're using
What workstation architecture and OS you're using
What type of license key arrangement you have
Whether your organization uses proxy servers or outbound firewalls
Whether this issue occurs with other users
