Unexpected error occurred by ua detach

[Nathan Teodosio]

[ Impact ]
Due to this race condition, user may seen unhanded exception when running a Pro command. Additionally, since the race condition is not obvious, users will be really confused on why the command failed in the first place

[ Test Plan ]
Because of the nature of this race condition, it is not straightforward to reproduce this issue. Our fix is basically trying to remove the file and handling the exception instead of checking if the file exists and then removing it. Since we call the function that generated this issue on several Pro commands that are covered in the integration test, we will assume that the full run will guarantee the we have not changed any behavior while addressing the race condition.

[ Where problems could occur ]
We don't believe any problems can occur here, as we are using a less error prone approach to deleting files in Python

[ Original Description ]
On Bionic, ua attach was successful, but a subsequent ua detach failed.

[Renan Rodrigo (renanrodrigo)]

Hello, Nathan
Thanks for reporting this bug.

Seems we hit a race condition when removing a file. If you try to detach again, does the error persist?

The team will be working on a solution.

[Nathan Teodosio (nteodosio)]

It doesn't anymore, though at this point I have executed several
attach/detach cycles (for testing another application). I cannot tell
whether my first detach attempt after the one I wrote this bug for was
clean or not, sorry.

[Renan Rodrigo (renanrodrigo)]

That's good - I missed the logs (:
It will be fixed next version.

Hello, Nathan - the test for this specific bug is part of the ubuntu-advantage-tools verification for SRUs, to be performed for https://bugs.launchpad.net/ubuntu/+source/ubuntu-advantage-tools/+bug/2029144

The team is working on that, and if something specific needs to be done about this bug in particular, a script or the steps will be added here.

[Lucas Albuquerque Medeiros de Moura (lamoura)]

We have already added the test result on the SRU bug:
https://bugs.launchpad.net/ubuntu/+source/ubuntu-advantage-tools/+bug/2029144

We have not experienced any issue caused by the race condition reported here and, as stated, we are calling the affected function multiple times on those tests and we not seen an issue. Because of that, we are marking this as verification done
