Description From 2015-12-03 21:29:51
apt-0.5.15lorg2-alt52

How to reproduce -- with an uninstalled package which changed between the
apt-get-updates:

apt-get remove tmux
apt-repo rm sisyphus && apt-repo add p6 && apt-get update

Start apt-shell (in another terminal) and don't close it.

apt-repo add sisyphus && apt-repo rm p6 && apt-get update

In apt-shell, do:

install tmux
commit

It aborts like this:

apt> install tmux
apt> commit
The following NEW packages will be installed:
  tmux
0 upgraded, 1 newly installed, 0 removed and 4 not upgraded.
apt-shell: rpm/rpmhandler.cc:119: virtual std::__cxx11::string
RPMFileHandler::Directory(): Assertion `HeaderP != __null' failed.
Aborted


A solution would be either for apt-shell to lock APT's data preventing any
other instances re-writing it (but not reading it), or for apt-shell to re-read
the data if it has changed.

Another case -- out of curiosity -- if the package list hasn't changed at all
between the apt-get-updates:

Start apt-shell (and leave it running).

[root@ovicaa apt]# apt-get update

In apt-shell, do:

apt> install tmux
apt> commit 
The following NEW packages will be installed:
  tmux
0 upgraded, 1 newly installed, 0 removed and 1602 not upgraded.
Need to get 0B/232kB of archives.
After unpacking 608kB of additional disk space will be used.
Do you want to continue? [Y/n] n
E: Operation cancelled.
apt> 

It doesn't abort.

Another case is a curious one, too -- what if the lists change, but the wanted
package doesn't:

apt-repo rm sisyphus && apt-repo add p7 && apt-get update

Start apt-shell.

apt-repo rm p7 && apt-repo add t7 && apt-get update

In apt-shell, do:

apt> install tmux
apt> commit 
The following NEW packages will be installed:
  tmux
0 upgraded, 1 newly installed, 0 removed and 173 not upgraded.
apt-shell: rpm/rpmhandler.cc:119: virtual std::__cxx11::string
RPMFileHandler::Directory(): Assertion `HeaderP != __null' failed.
Aborted


So, the change of the package is not essential.
(http://packages.altlinux.org/en/Sisyphus/srpms/tmux tells us that tmux is the
same in p7 and t7.)
