tags 963290 +patch thanks I just took a look at this issue.
First I did some digging in the upstream git repo. Once I figured out their branch structure (the "master0" branch is apparently where current releases are made from) I was able to find two relavent commits. 10ed02f429f75a418ee41814af2dffc8cd41101f which added support for flint 2.6.0 and cebabe52632013a70be321d590301e06c306a766 which removed the upper limit on the flint version. I applied these to the Debian package, in the process I found that 10ed02f429f75a418ee41814af2dffc8cd41101f conflicted with the existing debian patch upstream-fix-sprintf_buffer_overflow.patch, following the upstream issue report link for that patch lead to a claim the issue was fixed as part of 10ed02f429f75a418ee41814af2dffc8cd41101f so I removed upstream-fix-sprintf_buffer_overflow.patch from the series. Next I ran into an issue with a test failing to build because it could not find the newly added EANTIC_FIXED_fmpq_poly_add_fmpq symbol. I added the symbol to the version script. The final issue I ran into was that some symbols had disappeared. +#MISSING: 0.1.5+ds-2+rpi1# EANTIC_FIXED_fmpq_poly_get_str_pretty@LIBEANTIC_0_1_2 0.1.2 +#MISSING: 0.1.5+ds-2+rpi1# _EANTIC_FIXED_fmpq_poly_get_str_pretty@LIBEANTIC_0_1_2 0.1.2 +#MISSING: 0.1.5+ds-2+rpi1# _nf_elem_mod_fmpz@LIBEANTIC_0_1_2 0.1.2 +#MISSING: 0.1.5+ds-2+rpi1# nf_elem_mod_fmpz@LIBEANTIC_0_1_2 0.1.2 +#MISSING: 0.1.5+ds-2+rpi1# nf_elem_mod_fmpz_den@LIBEANTIC_0_1_2 0.1.2 I searched for EANTIC_FIXED_fmpq_poly_get_str_pretty and nf_elem_mod_fmpz on the codesearch.debian.net website . I also installed all the reverse-dependencies listed on the autoremoval list and then grepped in /usr/lib and /usr/bin . With the source search the only references I found were in the e-antic source package. With the binary search the only references I found were in libeantic.so.0.1.5 and libeantic.a. As such I decided it was probably ok to remove the symbols from the symbols file and went ahead and updated the symbols file. With that I was able to get a successful build in Raspbian bullseye-staging and I have uploaded the package to Raspbian. A debdiff should appear soon at https://debdiffs.raspbian.org/main/e/e-antic
