Update Repos sometimes just doesn't work.
Half the time, where I hit the Update Repos button, the dialog shows... but only for a second.
Repetitively hitting the button does not change anything.
I have a temporary workaround, toggling the repo switch twice, but this causes my next bug, the cause of my previous bug, #83 (closed) , which caused F-Droid to continually eat up storage
Edit:
I think this might be a duplicate/similar to #82 (closed)
LG Optimus Dynamic II (LG L39C) 4.1.2 JB 2GB internal memory 512MB RAM 1GHz single-core Snapdragon Factory ROM, no root, LG OEM skin.
Apparently hated by F-Droid.
