Symptom: auth.log shows a series of error message

Jul 25 23:57:38 gilead systemd-logind[738]: Suspending...
Jul 25 23:57:38 gilead systemd-logind[738]: Unit suspend.target is masked, refusing operation.
Jul 25 23:57:38 gilead systemd-logind[738]: Failed to execute suspend operation: Permission denied

This message has something to do with lid action of laptop, which could suspend system when lid is closed.

Solution

Edit /etc/systemd/logind.conf

with value HandleLidSwitch=ignore

Symptom: External HDD attached by USB 3.0 makes suspension during writing/reading disk, which causes timeout of inactivity in transferring data such as SFTP.

Solution: Just use USB 2.0 connection.

Symptom: Showing Error when assembling chunks, status code 504 after finishing upload in NEXTCLOUD
