Package: ghc
Version: 9.6.6-4
I tried to install ghc for as build dep for testing some stuff in
unstable, but it failed with:
Setting up ghc (9.6.6-4) ...
/usr/lib/ghc/bin/./ghc-9.6.6: error while loading shared libraries:
libHShaskeline-0.8.2.1-ghc9.6.6.so: cannot open shared object file: No such
file or directory
update-alternatives: using /usr/bin/ghc to provide
/usr/bin/haskell-compiler (haskell-compiler) in auto mode
/usr/lib/ghc/bin/./ghc-pkg-9.6.6: error while loading shared libraries:

or directory
dpkg: error processing package ghc (--configure):
installed ghc package post-installation script subprocess returned error
exit status 127
Steps to reproduce:
debootstrap sid sid
chroot sid
apt install ghc
Same issue applies of I debootstrap a trixie.

We have seen this error again [1], and it turns out that GHC's linker
needs '/proc/self/exec/ in order to work correctly [2].
[1] https://bugs.debian.org/773768
[2] https://bugs.debian.org/773768#113
Steps to reproduce:
debootstrap sid sid
chroot sid
apt install ghc
You need to mount '/proc' in your chroot here.
I will close this bug report, since this is not a bug in GHC.
Best,
