Thanks for trying to help me out! Settings | Storage
tells me that Sailfish OS dwarfs any other use of the space and the article doesn’t say much about shrinking it.
I already jettisoned most apps to be able to upgrade to 4.4.0.58 and then some (to no avail) to get to the next release. No longer having Android apps installed would allow me to remove app support, saving 145 MB (#2 storage consumer after SFOS), and there are 11 MB of logs I could get rid of…
Perhaps that would get me just enough room to upgrade once, but taking me through five releases all the way to 4.5.0.18? Sorry for being pessimistic, but I doubt it.
I can’t be certain what is the (cough) root cause, but something has been gradually filling up my root partition. Maybe SFOS just takes up more space now, maybe OS upgrades and/or app upgrades/removals don’t delete temporary objects.
I’m just mentally preparing for the effort and the downtime, as I’ve begun to think it would actually be good to start over with a fresh install.
