** Changed in: bcmwl (Ubuntu Natty)
Status: New => In Progress
** Changed in: bcmwl (Ubuntu Natty)
Assignee: (unassigned) => Luke Yelavich (themuso)
** Description changed:
+ SRU information for this bug:
+
+ Rationale
+ The pre-removal script assumes that there are instances of the bcmwl module
installed in the dkms tree prior to removal. In most cases this would be true,
but there are instances, such as in this bug, where the bcmwl module is not in
the tree, likely due to something the user has done. This stable update checks
to make sure there are instances of the module to remove before actually doing
so, making sure the package is removable in all circumstances.
+
+ Impact
+ This bug is likely to affect a low number of users, but does guard against
further breakage should something on a user's system break in the meantime.
+
+ Regression potential
+ The regression potential is low to none, given that an extra check is added.
+
+ How to reproduce (can be done on any system, even one without broadcom
wireless hardware)
+ 1. Install the bcmwl-kernel-source package.
+ 2. Remove the module from the dkms tree using "sudo dkms remove -m bcmwl -v
5.100.82.38+bdcom --all
+ 3. Remove the bcmwl-kernel-source package.
+
+ You should get the error that the original bug reporter described.
+
+ Once the updated package is installed, you should be able to follow the
+ above steps and receive no error.
+
+ Original bug report follows:
