I’ve recently encountered a problem – SVN went down on ubuntu server. I develop for Windows and I do not have much experience with Linux. I googled the error — without success. The error turned out to be the most typical one (the server unexpectedly closed the connection) and does not indicate anything. Therefore, it was necessary to go deeper and analyze logs/settings/rights/etc.
Finally, I figured out the mistake and found everything I needed, but I spent a lot of time. After solving this problem, I thought about how to reduce the uselessly spent hours and decided to write an article that will help people quickly get the understanding of the unfamiliar software.
