The first remake would have been Morre's from 2004. This is the second remake. I'm ignoring 1980.
Everyone ignores 1980.
There were a number of remake attempts. RDM was the only SUCCESSFUL remake. Before his, Bryan Singer and Tom Desanto were working on a continuation series when 9/11 hit. They had artwork, sets, 1:1 scale Vipers and a whole ton of camera-ready material that were scrapped in 2001. IIRC, some costume elements and set pieces were recycled for RDM's version.
During that time, Glen Larson was trying to get several TOS BSG-themed film projects going because he had ownership of feature film rights, not Universal, (including one Cain/Pegasus story) all failed.
After RDM's project, Bryan Singer tried, I think, 3 more times to do his own thing - the first time he was taken away for working on the X-Men series of movies (early 2000's - understandable). The next time, IIRC, was on account of Superman Returns (2006 - not so much). Then there was the Munsters Remake (2011 - don't get me started), and then one small mention of him several years later with another attempt in 2016 as a producer after Larson died in 2014 and Universal acquired the full property from his estate.
Every time brings us an explosion of interest and fan speculation, which invariably diminish into nothing, only to be resurrected again about 5 years later each time, to similar effect. Rinse and repeat. It is a sadly familiar refrain with this particular IP.
