Package: dpkg Version: 1.14.22 Followup-For: Bug #406715 Hi,
the same problem happens, when a directory is replaced by a symlink during the upgrade of a package. I am attaching 2 versions of the testpackage tp to illustrate the problem. Version 1 ships the file /usr/lib/tp/tp.cfg and the directory /usr/lib/tp/log. Version 2 moves tp.cfg to /etc and the directory to /var/log/tp and ships appropriate symlinks in /usr/lib/tp/. After the installation of version 1 we have: $ ls -l /usr/lib/tp insgesamt 4 drwxr-xr-x 2 twerner twerner 4096 12. Okt 15:51 log -rw-r--r-- 1 twerner twerner 0 12. Okt 15:51 tp.cfg After the upgrade to version 2 we have: $ ls -l /usr/lib/tp insgesamt 4 drwxr-xr-x 2 twerner twerner 4096 12. Okt 15:51 log lrwxrwxrwx 1 twerner twerner 11 12. Okt 16:00 tp.cfg -> /etc/tp.cfg After the installation of version 2 on a fresh system we have the correct symlink: $ ls -l /usr/lib/tp insgesamt 0 lrwxrwxrwx 1 twerner twerner 11 12. Okt 16:00 log -> /var/log/tp lrwxrwxrwx 1 twerner twerner 11 12. Okt 16:00 tp.cfg -> /etc/tp.cfg The maintainer of tp can handle that problem via preinst but it is difficult to spot because dpkg does not fail during the upgrade (no warning either). Because I have seen RC bugs because of this (#468954) I will increase the severity of this bug to important. IMHO dpkg should fail is such cases with a useful error message.
