Tried to update chum repositories and get the error message: Failed to refresh sailfishos:chum repository
SailfishOS 5.0.0.77, Xperia 10 III
You can go to Chum settings and manually enter 5.0.0.76 (not 77) and press Enter.
This should work.
As far as I know, entering 5.0 is enough, no need minor etc. version numbers.
