gupnp-igd16-dev.tcz.dep currently looks like this...
gupnp16-igd.tcz
gupnp16-dev.tcz
...but there is no extension named gupnp16-igd.tcz.
The file should be corrected to this:
gupnp-igd16.tcz
gupnp16-dev.tcz
EDIT: I only checked the TCL16 x86_64 repo. Please take a look in the TCL16 x86 repo to see if the same correction is needed.
