Upgrades are always a pain for me. When 13.0.5 hit stable, I entered the updater, and had to chmod a bunch of files to get it to work. When it got to “Delete old files”, it got stuck with an error message that says:
Parsing response failed. <html> <head><title>502 Bad Gateway</title></head>
<body bgcolor="white"> <center><h1>502 Bad Gateway</h1></center>
<hr><center>nginx/1.14.0</center> </body> </html>
This is completely cryptic to me. Didn’t happen the last time I updated. (Last time, there was a different problem, and I had to manually copy the downloaded files from my data folder to my nextcloud folder.)
