The new library needs the new ''glibc'' package, ''gpg'' stops working because of the library linking error, and ''slackpkg'' will stop the system upgrade because it wants to check every package's gpg signature before upgrading it. Upgrading the ''glibc-solibs'' package prevents the library linking errors by providing the correct "''GLIBC''" symbols.+</code> Let me give an example of such potential failure: when ''slackpkg install-new'' installs the ''libusb-compat'' package, your ''gpg'' command stops working because it links against libusb.so which will be overwritten with the version from the new ''libusb-compat'' package.
