Package: dbconfig-common
Version: 1.8.13
Severity: normal
When there are no configuration files in /etc/dbconfig-common the config
maintainer script suffers an error as it does not check the result of a
shell expansion.
The offending code is lines 199-202 of dpkg/config.
The root cause is that the expansion will return the literal string
"/etc/dbconfig-common/*.conf" if it could not match any actual
configuration files. This string is then passed directly into
dbconfig-generate-include which generates an error as shown below:
Unpacking db-test-sqlite (from db-test-sqlite_2.0_all.deb) ...
Setting up db-test-sqlite (2.0) ...
unable to read input file /etc/dbconfig-common/*.conf
dpkg: error processing db-test-sqlite (--install):
subprocess post-installation script returned error exit status 10
As the script is set -e this causes the installation to fail.
The patch below offers one possible solution to the problem,
alternatively dbconfig common could run 'shopt -s nullglob' to request
bash returns an empty string when the expansion fails.
