Errors upgrading to 4.2

Hello!

I am having trouble upgrading.

Checking for release updates:                          The connection to the repository server failed: Configuration error: Network is unreachable. Please check the repository configuration and the network connection.

So I check in sources lists

root@controller:/home/julian.somers# cat /etc/apt/sources.list.d/15_ucs-online-version.list 
#Warning: This file is auto-generated and might be overwritten by
#         univention-config-registry.
#         Please edit the following file(s) instead:

#

# An error occurred during the repository check. The error message:
#   Traceback (most recent call last):

#

# After fixing this issue, you should rewrite this file with the following command:
#   univention-config-registry commit /etc/apt/sources.list.d/15_ucs-online-version.list
#


root@controller:/home/julian.somers# cat /etc/apt/sources.list.d/20_ucs-online-component.list 
#Warning: This file is auto-generated and might be overwritten by
#         univention-config-registry.
#         Please edit the following file(s) instead:

# Configuration error: Network is unreachable: cool-solutions
# Configuration error: non-existing component prefix: https://updates.software-univention.de/: 4.1-4-errata




So I try ucr commit /etc/apt/sources.list.d/* but it fails again

root@controller:/home/julian.somers# cat /etc/apt/sources.list.d/20_ucs-online-component.list 
#Warning: This file is auto-generated and might be overwritten by
#         univention-config-registry.
#         Please edit the following file(s) instead:

# Configuration error: Network is unreachable: google-apps_20160901141413
deb https://updates.software-univention.de/4.1/unmaintained/component/ cool-solutions/all/
deb https://updates.software-univention.de/4.0/unmaintained/component/ cool-solutions/all/
deb https://updates.software-univention.de/4.0/unmaintained/component/ cool-solutions/amd64/
# Configuration error: non-existing component prefix: https://updates.software-univention.de/: 4.1-4-errata

And so it goes – sometimes after ucr commit there are valid entries in 20_ucs-online-component.list and the upgrade gets going but it eventually fails, and when I check, those entries are gone, replaced either by tracebacks like those above or simply #Configuration error: Network is unreachable. Each time the errors are slightly different,

My network doesn’t seem to be misbehaving – I can ping updates.software-univention.de without loss while these failures happen.

here is our repo listing

I considered disabling the offending repos during the upgrade, but thought that might be dangerous, I should check here first!

Many thanks for your help, Julian

Do you tried to ping the servers like in this thread?

I didn’t try to telnet the servers, but I did try to open the repo URL in a browser – that worked.

Since Saturday this problem seems to have fixed itself – at least the sources.list files are properly populated now.

I can only assume now that there was a transient problem on the repo servers.

We won’t know for sure until I try univention-upgrade next maintenance window, perhaps wednesday night.

thanks for your help, Julian
