Describe the bug
Newly installed 1.80 via cPanel, imported my (less than 100) feeds i prevoiusly exported via an outdated (cPanel) tt-rss instance

feeds don't automatically update. Single feeds when forced update do show new items. Trying to force a complete feed refresh doesn't work

looking at logs there is an error:

2021-03-22 10:23:59
SQL error updateTTL 2: Duplicate column name 'ttl' ALTER TABLE _feed ADD COLUMN ttl INT NOT NULL DEFAULT 0
2021-03-22 10:23:59
SQL warning updateTTL 1: Deadlock found when trying to get lock; try restarting transaction UPDATE _feed SET ttl=:new_value WHERE ttl=:old_value

Environment information (please complete the following information):

Additional context
I suspect there's an issue with updating imported tt-rss exported feeds.
