jnatschev commented 3 years ago

hello. i noticed an email message that 2.2.25 was released. i started my gns3 vm 2.2.24 (i already had a snapshot) at the information screen, i pressed enter from the menu, i selected upgrade i selected "Yes" from the next dialog i hit enter on the already highlighted v2.2.25 the process went through the upgrade and the gns3 vm rebooted after the boot up and return of the front menu, the version reported 2.2.17 i had installed gns3 gui 2.2.25 while the gns3 vm was upgrading and started gn3 gui and gns3 gui reported a version mismatch: gns3 gui 2.2.25, gns3 vm 2.2.17

did i jump the gun?

grossmj commented 3 years ago

I suspect an issue with setuptools that we have upgraded recently. I made a change to our upgrade scripts, please try if it fixes the issue on your side. You will have to restart the VM once and then start the upgrade.

jnatschev commented 3 years ago

just tried again. followed as close as possible the upgrade process. right at the very end the upgrade process said that the upgrade to 2.2.25 was done and wait 10 seconds. the vm rebooted and returned to the information screen with the gns3 server version at 2.2.17 again.

jnatschev commented 3 years ago

i just tried to upgrade to 2.2.24. the upgrade process succeeded. after the reboot, the gns3 server version was 2.2.17 again.

jnatschev commented 3 years ago

if there's something i can gather let me know how to gather it and i'll do it. i'm ok for now. i'm not going to use my snapshot. i can wait a bit before doing that.

grossmj commented 3 years ago

@jnatschev please can you try different upgrades, like going to 2.2.22 and then back to 2.2.25? Thanks 👍

jnatschev commented 3 years ago

going to 2.2.22 resulted in upgrade completed and upon reboot gns3 server version 2.2.17. i still tried from here to upgrade to 2.2.25, same result, gns3 server version 2.2.17.

i just remembered something that may or may not be of value. when i performed a fresh installed the gns3 vm it was version 2.2.17.

potentially a file link issue. i did a bit of digging around and tried stuff manually.

the fact that it is permission denied doesn't bother. but part of the upgrade worked because 2.2.25 is there.

i tried again by restoring my pre upgrade snapshot (2.2.24). same result after the upgrade, gns3 server 2.2.17.

grossmj commented 3 years ago

There must be a problem with the GNS3 VM that came with v2.2.17 :thinking: I have downloaded the GNS3 VM for v2.2.24 and was able to switch between versions.

jnatschev commented 3 years ago

yeah. too right. i reverted to my last known working gns3 vm, 2.2.24. did a bit more digging around. found that this directory "/usr/local/lib/python3.6/dist-packages" contained a directory named "gns3server". i output the contents of the version.py file in this directory and it was, low and behold, 2.2.17. i renamed this gns3server directory to gns3server.backup. i ran the 2.2.25 upgrade process again. hey presto! 2.2.25. all is good with the world again. YAY!

out of curiosity, is there a procedure to migrate all relevant files of appliances and projects from one vm to another vm? i tried searching for the answer and wasn't really able to find anything definitive; hence the question.

warnesj commented 3 years ago

Thanks @jnatschev! Your workaround of renaming the /usr/local/lib/python3.6/dist-packages/gns3server directory and re-trying the update worked for me too.

jnatschev commented 3 years ago

Awesome.

Cheers, John

One way to do it is to use the "Migrate" option in the VM menu.

cheers @grossmj. my apologies for even asking. i ought to have read the menu options before asking. i'm a dill.

grossmj commented 3 years ago

I changed the upgrade process to use PyPi instead of our GitHub repository: https://github.com/GNS3/gns3-vm/commit/08fd67d091e79a7944740cf73298914dce33ffd7

This should fix this issue and also allow for faster upgrades.

jnatschev commented 3 years ago

cool. thanks.
