cant update anything after power outage certificate error

Please provide a link to a page on your site where we can see this. Thanks.

I suspect that if the power failure were on your computer, rather than the server, you may have some corrupt files that need to be repaired/restored.

the power outage was both my pc and the server (two separate machines)

my server reported file system errors and required me to run a file system scan before booting into turnkey lamp. the scan appeared to find two errors and corrected them both.

Try reinstalling the openSSL libraries.

im a bit of a linux noob im afraid
