Kopano core for ubuntu 20.04

hodor27

@fbartels followup question: Can you give a rough estimate when kopano-server packages will be released for Ubuntu 20.04 ? 2020/Q2?
thx!

fbartels

@hodor27 for master we are already building these packages, but they have simply not been uploaded because the release chain is failing. But be aware that these builds do not come with any guarantees.

hi

I have dpkg-reconfigure php7-mapi and uninstall phpmyadmin from ubuntu 20.04
then install phpmyadmin from here
wget https://files.phpmyadmin.net/phpMyAdmin/5.0.2/phpMyAdmin-5.0.2-all-languages.tar.gz
then everything is working for now, both load of php7-mapi and phpmyadmin

Thanks for the report. I have created https://jira.kopano.io/browse/KC-1770 so that the packaging can be adjusted.

Hi

When I use kopano-migration-imap on kopano 10.0.4 and ubuntu 20.04
I get this error in sydlog every 1 sek.

] SQL [00044871] result failed: Deadlock found when trying to get lock; try restarting transaction, Query: “SELECT 1 FROM properties WHERE hierarchyid IN(118958) LOCK IN SHARE MODE”

but the tool is working I can move mail from old kopano to new

Claus

@cbnidk yes, it will work since the transaction will be retried. But ultimately this means you need to improve your database tuning.

Some mysql can be applied with a restart, some others may need a dump and restore of the database.

I have never done that before

Importing data does put a different load on the database than the usual daily usage.

Hi

I have tuned the database with this

innodb_buffer_pool_size = 3GB
innodb_log_file_size = 750M
innodb_log_buffer_size = 32M
max_allowed_packet = 32M
max_connections = kopano (server.cfg) threads(default 8) + thread_limit(default 40) + 9

but I have to # out the last line
max_connections = kopano (server.cfg) threads(default 8) + thread_limit(default 40) + 9
otherwise the copano server will not start
is this line important?
fornow it is # out,

I would not set the log file size that high. rather have multiple smaller files.

but I have to # out the last line

otherwise the copano server will not start

Why doesnt it start? What is the error message?

But it don’t help

Slow disk maybe? Tuning is more than just configuration.

Edit: there are also way more parameters you can tune in MySQL for customers we have a detailed tuning guide that our support can send out.

Hi

@cbnidk

hi

in my server log I got this one or two time a day

SQL [00020233] info: MySQL server has gone away. Reconnecting.
is there a way to fix this?
mysql config =
innodb_buffer_pool_size = 1600M
innodb_log_file_size = 400M
innodb_log_buffer_size = 100M
max_allowed_packet = 16M
innodb_file_per_table = ON
key_buffer_size = 400M

kopano 10.0.4
ubuntu 20.04

Claus

@cbnidk which version as you using exactly. There was recently an issue with stale mysql connections, but that hs been solved meanwhile.

If its just a mysql connection being closed after reaching the connection timeout I would no worry about it.

cbnidk

hi

my ver. is kopano-server_10.0.4.79.bbc9fa6e6-0+91.1_amd64.deb
for ubuntu 20.04

Claus

fbartels

the latest is 10.0.5.2.9bfb891a3-0+102.1.

But is most probably just a connection timeout.

thctlo

You should verify if mysql/mariadb is fully updated.

My upgrade from 18.04 to 20.04 needed some fixing after the upgrade.
apache2 stopped working, mysql stopped working, thinks like that.
it also changed my interface from 0.0.0.0 to 127.0.0.1, i had to correct it manualy again.
check these things.

Which i never have these things in a same setups on Debian itself.
Always problems with Ubuntu and dist upgrades…
