[Users] vzlinux 8 pb update package python2

well, that was the '--nobest' option that allowed me to sucessfully update all other packages : 

$dnf update --nobest 
... 
Skipped: 
python2-for-tests-2.7.17-1.vl8.2.x86_64 python2-libs-2.7.18-4.module_vl8+478+7570e00c.x86_64 
Complete! 

next I removed python2-for-test, and here there was no more dependence on mongodb, so I could proceed . 

# dnf remove python2-for-tests 
removed: 
python2-2.7.17-1.vl8.1.x86_64 python2-for-tests-2.7.17-1.vl8.1.x86_64 python2-libs-2.7.17-1.vl8.1.x86_64 
complete ! 

My system is up2date now , thanks .

Yes, looks like the '--best' option works fine here. It is ok to leave python2-for-tests with broken dependencies. Once you update python2 itself to a modular package, you should be able to remove python2-for-tests without any problems.

this CT serve a rocketchat service that needs mongodb, I don't want to break the databse service . 

as suggested by DNF , there's the "--nobest" option which seems to go further , but with this warning 

Enabling module streams: 
httpd 2.4 
mariadb 10.3 
Skipping packages with conflicts: 
(add '--best --allowerasing' to command line to force their upgrade): 
python2-libs x86_64 2.7.18-4.module_vl8+478+7570e00c virtuozzolinux-base 6.0 M 
Skipping packages with broken dependencies: 
python2-for-tests x86_64 2.7.17-1.vl8.2 virtuozzolinux-base 79 k 

is this the "best" option ? 
thanks .

Hi, 

this looks like a subsequence of python2 installed from the main repo and not from module. I remember that for some time we indeed didn't have python2 in module so this could happen easily. 

I'd suggest to simply remove python2-for-tests package. 

And in general this is how new modules/streams work - you can have multiple versions of the same package in repos in different streams (python2-libs in our case), but you still can't install them simultaneously. And modular package always has s higher priority unless you configure a special option in the repo file.

Hello 

I've moved some CTs to vl8 , but now at least with this one , I have dependancy problemes

is there a repository inconsistancy ?
