Public bug reported:
The apt configuration database has some incompatible changes which break
existing scripts. It is not obvious that this was deliberate (I hope
not).
Prior to 16.10, the configured cache directory path(s) included a
trailing slash. Now they do not include the trailing slash. This
breaks existing scripts which combine bits from the configuration
database.
In 16.04:
$ apt-config shell D Dir C Dir::Cache F Dir::Cache::pkgcache
D='/'
C='var/cache/apt/'
F='pkgcache.bin'
So if this output is eval'd in the shell, then
path=${D}${C}${F} produces "/var/cache/apt/pkgcache.bin"
However in 16.10:
$ apt-config shell D Dir C Dir::Cache F Dir::Cache::pkgcache
D='/'
C='var/cache/apt'
F='pkgcache.bin'
So existing shell code now breaks
path=${D}${C}${F} produces "/var/cache/aptpkgcache.bin"
If this was a mistake, please fix ASAP.
If it was on purpose, please post (a link to) an explanation.
Thanks.
