Solution “Internal Server Error” when opening Nextcloud

Recently moved Nextcloud from one server to another and when it opened, noticed the following error in the browser:

Internal Server Error

The server encountered an internal error and was unable to complete your request.
Please contact the server administrator if this error reappears multiple times, please include the technical details below in your report.
More details can be found in the server log.

In my case, the error occurred because of a damaged MySQL database, so I restored it from another backup and Nextcloud opened.
I assume that the same error can occur when the Nextcloud database exists, but is empty.

How to see the process of importing a SQL file?

In order to see the process of importing SQL files, I use the Pipe Viewer utility.
Pipe Viewer is very useful especially when the SQL file is large, allows you to roughly estimate the remaining time before the import of the file is completed, displays the import process in percent and the time passed.

Configuring Huawei Quidway S3900 Switches

For example, take the switch Huawei Quidway S3928P-EI, the settings are essentially suitable for the entire Huawei Quidway S3900 series, but may differ slightly depending on the firmware version. If something fails to register, then you can see the options for the teams by typing a question mark after a space after any command.

At me at switching-on of the switch, through the console the following characteristics were displayed:

Creation date: Aug 25 2006
CPU type: BCM4704
CPU Clock Speed: 200MHz
BUS Clock Speed: 33MHz
Memory Size: 64MB

Let’s see the current configuration with the command:

display current-configuration

To enter the configuration mode, type:

system-view

Solution of error with binary-mode when importing MySQL dump from the command line

Once I decided to import sql dump:

mysql -u root database < database.sql.gz

And I noticed the following error:

ERROR: ASCII '\0' appeared in the statement, but this is not allowed unless option --binary-mode is enabled and mysql is run in non-interactive mode. Set --binary-mode to 1 if ASCII '\0' is expected. Query: ''.

The error occurs because the dump is compressed and must first be unpacked:

gunzip database.sql.gz

And then import:

mysql -u root database < database.sql
