contention for /usr/lib64 in libc6 and base-files
If I try to install (update) libc6, I get
dpkg: error processing /var/cache/apt/archives/libc6_2.3.2.ds1-18.104.22.168.pure64_amd64.deb (--unpack):
trying to overwrite `/usr/lib64', which is also in package base-files
If I try to install (update) base-files, I get
The following packages have unmet dependencies:
base-files: PreDepends: libc6 (>= 2.3.2.ds1-22.214.171.124.pure64) but 2.3.2.ds1-19 is to be installed
libc6-dev: Depends: libc6 (= 2.3.2.ds1-126.96.36.199.pure64) but 2.3.2.ds1-19 is to be installed
E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).
And of course, apt-get -f install tries to install libc6, so
I'm back to square one. How do I recover from this?
I understand from reading e.g.,
that some of these links are critical for the system's operation,
so I don't want to charge ahead without some idea where I'm going.
