Bug Description
Running two apt-get instances in parallel results in
...
1: kernel-
#######
[100%]
/
Running /usr/lib/
warning: failed to restore database lock
(with 'apt-get install update-kernel' running in parallel)
After this apt-get says that kernel-image is installed, while rpm says that it is not.
Files from the package do exist in the system
This problem can be likely solved by cleaning apt caches, though this is not convenient.

Thank you for the translation.
There are 2 coupled issues that are pertinent to ROSA planning here
(in spite of this being an Alt bug on a heavily patched older version of RPM)
1) file pattern triggers
rpm5.org is carrying 2 file trigger implementations at the moment.
One of the implementations originally came from Mandriva (and might
be what is back ported to Alt, I haven't looked).
There's another implementation (from me) that extends %trigger syntax
to use patterns on file/directory paths. The %trigger implementation
was undertaken so that the scripts that run are directly present in
*.rpm packaging and fit into existing *.spec syntax in a "natural" way. The
Mandriva file triggers are entirely opaque to rpm which merely reads
patterns and runs scripts. The problem is that rpm gets blamed for
configuration failures because of the mechanism and its rather difficult
QA to find/fix reproducers when they occur.
One of Per Oyvind's wiki page bugs is related to this same issue.
2) apt-rpm support
Yes, the "cache" in apt leads to a class of problems that are similar
to the rpmdb "database" problems routinely reported as rpm "bugs".
Meanwhile -- if ROSA is considering distributing/
then blueprints and planning needs to be undertaken.
