Segmentation Fault upon fresh installation

@ivanlaszik said in Segmentation Fault upon fresh installation:

any advice?

What happens if you try removing the package?

I did that, by #dnf remove compat-openssl10, and it offered to remove 64 packages, among them all the kopano packages.

what else to do for troubleshooting?

I’d recommend to stick with a distribution that is also used for the supported packages (see https://documentation.kopano.io/kopanocore_administrator_manual/installing.html#supported-platforms for an overview). The listed distributions are tested on a regular base and should therefore (theoretically) be free of such errors.

Thanks fbartels. My current working (old) zarafa installation is on Fedora 22 and there were no issue from the beginning.
For personal use I love to play with cutting edge stuff, reason why I choose Fedora.
I am sure it will work with CentOS7, with which I will go if I cannot make it on FC, but in the meantime I really want to work it out with FC26.

I also get a sig-segfault exception on Ubuntu 16.04.3 LTS upon running kopano-admin -l

/var/log/syslog

upon a fresh install of kopano the first segfault i get is from spooler:

the backtace for kopano-spooler looks similiar to the one kopano-admin produces:

@ivanlaszik said in Segmentation Fault upon fresh installation:

Downloaded build core-8.4.90.1338_0+158-Fedora_26-x86_64 on Dec. 12.

F26 build now (kopano-8.4.90.1513-170.1) uses openssl 1.0 throughout. Maybe that cures the issue.

ivanlaszik

installed core-8.4.90.1513_0+172-Fedora_26-x86_64 just now and creation of the admin user was succesfull.
upgraded webapp to 3.4.3.1127+669 also, however, i get following error in httpd error log upon login attempt:

and browser shows:

HTTP ERROR 500

I don’t think this is related to the previous problem.
i am researching, but any advice is appreciated.

ivanlaszik

fixed the above by installing php-xml.

all is good now, kopano seems to be working.

thanks for all the help and input :).
