[Bug 716599] Re: apt can't open package cache under certain circumstances

[Jonathan Thomas]

Ah, sorry forgot about this. At UDS David and I initially discussed it
and did agree that the error was coming from APT. I had to get somewhere
so I quickly came here and sent the bug back to new. We later went
through QApt's code and found that its function for calculating download
used a fetcher that could potentially raise errors. These errors were
not being cleared from APT's error system, so when QApt went to reload
the cache the errors would still be there, tripping up QApt in to
thinking that the cache reload failed.

QApt now discards all errors incurred in its downloadSize() function,
fixing this issue. I'd like to apologize for not giving a decent
explanation for setting the bug back to new, and for forgetting about
the Launchpad bug for this long after UDS.

** Package changed: apt (Ubuntu) => qapt (Ubuntu)
