LE 9.95.1: Backups are restored with mtime Jan 1 1970 for some files (with testcase)

bjohv052 · March 28, 2021 at 7:51 PM

I suddenly got an error message from the Watchedlist add-on that "zip does not support dates older than 1980". Turned out some of the files belonging to the add-on had a modification time of Jan 1 1970. After some time I managed to track the error down to a restored backup and there were lots of other files with a modification time of 1 Jan 1970. Here is a test case to reproduce the error that shows that backups are either wrongly created or wrongly restored in LE 9.95.1. It works in 9.2.6. All tests were carried out on the same hardware, a Qotom Q150S.

Look at ~/.kodi/media and ~/.kodi/system below.

Code

Freshly installed 9.95.1:

Do backup of the same and restore it:

Can you repeat a clean restore on 9.95.1 then run "journalctl | paste" about 30 seconds after boot and share the URL generated. I'm wondering whether the box has an RTC chip or gets time from NTP? .. and whether time has been correctly set at the point the restore is performed.

Do you see the wrong dates only on empty directories?
