Some or all of the below information will be requested if it isn’t supplied; for fastest response please provide as much as you can
Nextcloud version (eg, 12.0.2): 17.0.2.1
Operating system and version (eg, Ubuntu 17.04): Ubuntu 19.10
Apache or nginx version (eg, Apache 2.4.25): Apache 2.4.41
PHP version (eg, 7.1): 7.3
Database: mariadb 10.3
Desktop sync clients: Windows and Ubuntu
The issue you are facing:
When I try to open folders containing special characters (such as space, “(”, etc.), I cannot. I cannot generate error messages. When I try to open the folder from the browser it just doesn’t open it. Also desktop sync returns, internal server error for folders and cannot sync files. Interestingly, I can download files containing spaces in their file names.
Update: I started to believe that the problem is related to database connection to PHP or PHP’s handling of UTF-8
More on the issue:
I migrated to my server from Raspberry Pi 3B+, running an Opensuse Leap 15.1 to a Raspberry Pi 4 4GB, running an Ubuntu 19.10. I set it up manually and quite easily. On the front end everything looks normal.
Is this the first time you’ve seen this error? (Y/N): Y
Steps to replicate it:
- Migrate server to Ubuntu 19.10 on Raspberry pi
- Setup mariadb
- Try to open a folder containing space as character in it

I’ve found this in the Error log, but I’m not sure, I wasn’t able to replicate it.
