Status: RESOLVED WORKSFORME

(Calendar :: Provider: CalDAV, defect)

User Agent: Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:59.0) Gecko/20100101 Firefox/59.0
Build ID: 20180326161606

Steps to reproduce:

Hello All,

I have a self-hosted caldav server. I've synchronized it for months successfully with my windows 7 client + Thunderbird (also with my mobile phone).

Today, I booted my Ubuntu 14.04 client after some months the first time.
First I had to add the calendar again because I changed SSL certificates in the meantime (removed previous calender first)
After that I synchronized Lightning.

Environment
---------------
Windows Client:
+ Win 7
+ Thunderbird 52.7.0
+ Lightning 5.4.7 (latest stable version)

Ubuntu Client:
+ Ubuntu 14.04
+ Thunderbird 52.7.0
+ Lightning 5.4 (latest version in the official repository)

Caldav Server:
+ Radicale


Actual results:

1. Synchronization on Ubuntu 14.04 started and finished after a few seconds
2. I added a new appointment - nothing happend, but the appointment didn't appear in the calendar
3. After 5-10 minutes it appeared in the calendar
4. After a sync of my mobile phone, all appointments on the phone seemed to be  gone
5. I  checked the ICA-directory of the Caldav server -> found many files there
6. I compared the files with the backup - it turns out, that Lightning on Ubuntu replaced each and every ica-file with a completely different file-name. All files had today's timestamp. Also, the content changed slightly - but the appointments were basically the same.


Expected results:

Synchronization between Windows and Ubuntu via caldav server should work fast in both directions.

ICA files of the caldav server must not be replaced by different files / filenames.

New appointments should be added as a new ica file but without affecting existing files

Thank you in advance
M.

I think this bug can be closed now.
In the meantime, I do not use windows any more. My ubuntu version is now 22.04 and my calendar server is baikal.
Syncing works for me in any direction and with any system I use (android, ubuntu).

Will close the bug.
