How to fix mysql installation error?

Question

LAMP

Good evening guys, this is the first time I've encountered such a problem.
After installing apache2, I put (already tried this and that and + rebuilding the server) mysql, lamp, phpmyadmin (whatever you do, don’t put all the errors)
Errors were encountered while processing:
mysql-server-5.7
mysql-server
E: Sub-process /usr/ bin/dpkg returned an error code (1)
I don't know how to defeat them already, who can help?

Answer 1

It just didn't fit in my memory. It would be possible to reduce innodb_buffer_pool_size, for example, or somewhere else to reduce memory consumption so that mysql can start.

Answer 2

Paste the last line of the error into Google and search.
There are a lot of answers there.
