In fact I uploaded wireshark to the 6.x corepure64 repo a while back, but forgot to upload the info file, so it wasn't visible in either the 6.x or 7.x repos.
Anyway, I uploaded an updated version to the 7.x corepure64 yesterday with these deps: gtk3.tcz
libpcap.tcz
libnl.tcz
gnutls.tcz
libgcrypt.tcz
lua-5.3-lib.tcz
sbc.tcz
c-ares.tcz
portaudio.tcz
libssh.tcz
libgeoip.tcz
..and things look better with adwaita-icon-theme loaded.
