Package: libfl-dev Version: 2.6.4-8.1 Severity: serious Justification: dpkg unpack error
Attempting to unpack libfl-dev/2.6.4-8.1 from Debian bookworm on a minimal Debian bullseye with flex-old/2.5.4a-10.1 installed, causes an unpack error from dpkg due to /usr/include/FlexLexer.h being contained in both packages. | Selecting previously unselected package libfl-dev:amd64. | (Reading database ... 4697 files and directories currently installed.) | Preparing to unpack .../libfl-dev_2.6.4-8.1_amd64.deb ... | Unpacking libfl-dev:amd64 (2.6.4-8.1) ... | dpkg: error processing archive ./libfl-dev_2.6.4-8.1_amd64.deb (--unpack): | trying to overwrite '/usr/include/FlexLexer.h', which is also in package flex-old 2.5.4a-10.1 | dpkg-deb: error: paste subprocess was killed by signal (Broken pipe) | Errors were encountered while processing: | ./libfl-dev_2.6.4-8.1_amd64.deb Please ensure that libfl-dev has sufficient Breaks and Replaces declarations.
