find /var/log/ -name '*.gz' -exec rm {} +
Note: Concluding with ‘+’ rather than ‘\;’ should be faster by not running rm on every instance from find.
find /var/log/ -name '*.gz' -exec rm -i {} +
find /var/log/ -name '*.gz' -exec rm -r {} +
find /var/log/ -name '*log' -type f -exec truncate -s 0 {} +

After running updates, carbon-cache throws the folling error on a service restart.

This seems to relate to changes to TLS version support in pyOpenSSL/OpenSSL. I’m not using TLS for carbon-cache, I don’t think, so disabling the reference in Twisted framework’s respective file should be fine. Comment out the lines referenced in the above error, like so:
