Can't update 3650 from 3.7.5

[ondjultomte]

I got a  WS-C3650-48PS      03.07.05.E in BUNDLE mode that I tried to upgrade.

I tried to just add the standard boot system flash:image.bin and switch to INSTALL mode with the packages.conf as boot file.

The problem is that each boot system command just adds to the boot variable parameter, so I can't change from the old boot image.

ie:

# show boot
---------------------------
Switch 1

Current Boot Variables:
BOOT variable = flash:cat3k_caa-universalk9.SPA.03.07.05.E.152-3.E5.bin;flash:packages.conf;flash:running-packages.conf;flash:3.7.5.bin;flash:cat3k_caa-universalk9.16.03.06.SPA.bin;flash:3.7.5.bin;flash:packages.conf;

Boot Variables on next reload:
BOOT variable = flash:cat3k_caa-universalk9.SPA.03.07.05.E.152-3.E5.bin;flash:packages.conf;flash:running-packages.conf;flash:3.7.5.bin;
Allow Dev Key = yes
Manual Boot = no
Enable Break = no

How can I empty the BOOT Variable string? As a last resort Iäm thinking of renaming my packages.conf file to cat3k_caa-universalk9.SPA.03.07.05.E.152-3.E5.bin , or I can rename the image that I want to run 16.3.6 to this old filename 3.7.5, but I would prefer to change to INSTALL mode.

Renaming cat3k_caa-universalk9.16.03.06.SPA.bin to cat3k_caa-universalk9.SPA.03.07.05.E.152-3.E5.bin , and if the switch boots correctly with version 16.3.6 even tho the bin filename isnt correct might solve this bug ? and I could then change from BUNDLE to INSTALL mode.

Hi,

To move from bundle to install mode, you will need to expand the cat3k_caa-universalk9.16.03.06.SPA.bin file and then update the boot variable. Follow the steps in the following doc under the "Move from Cisco IOS XE 3.xE Bundle Mode to Install Mode" section:

Thanks

Yes I know, the problem is the BOOT variable ! the first entry is persistent hence packages.conf will never be read.

The boot variable just keeps getting longer and longer, every string just just added !

Hi, Have you tried deleting the variable with the "no boot system" command? Thanks John

Hi, never thought of that  :)

Switch 1
---------------------------
Current Boot Variables:
BOOT variable = flash:packages.conf;flash:cat3k_caa-universalk9.16.03.06.SPA.bin;flash:cat3k_caa-universalk9.SPA.03.07.05.E.152-3.E5.bin;

Boot Variables on next reload:
BOOT variable = flash:cat3k_caa-universalk9.SPA.03.07.05.E.152-3.E5.bin;flash:packages.conf;flash:running-packages.conf;flash:3.7.5.bin;

Now the current boot variable is changed, but the variable on next reload is the same.

hi, What happens when you save the config? thanks John

Hi ! Now I did some more testing.

First I tried:

no boot system
end
wr

no difference , then I tried

no boot system flash:thefiletoberemoved
end
wr

no difference.

But Right now I tried it again and it worked
