We are currently receiving these kind of error messages when updating our tezos node.

Our upgrading procedure are like this: 1. We copy the main ~/tezos directory to a new directory called ~/tezos-new. 2. Call update command as shown below. 3. Stop node, change directory names, and start node again.

Using this command:

cd ~/tezos-new && eval $(opam env) && make clean && git checkout mainnet && git pull && make clean && make build-deps && eval $(opam env) && make && cd ~

We get errors like this:

[ERROR] No switch is currently set. Please use 'opam switch' to set or install a switch
make: dune: Command not found
Makefile:118: recipe for target 'clean' failed
make: [clean] Error 127 (ignored)

Any insight is much appreciated.

In the end the node is updated, and is running latest block and everything. Just wanted to get more insight into this message. Thanks.

- Acho que você deveexecutar o "opaminit"primeirononovo diretórioparainicializar o opamenve quetambém definirá ointerruptor de opam
  
  I think you should run `opam init` first in the new directory to initialize opam env and that will also set opam switch

  Then it ask me to modify "~/.profile" so that eval$(opam env) isn't required every time I want access the opam installation. Saying yes to this still gives me the switch error message at the beginning. But thanks for the feedback.

- Você copiou ~/tezospara ~/tezos-novo sem limpar os artefatos de construção? Se houver um subdiretório "_OPAM"em ~/tezose vocêtenta copiá-lopara ~/tezos-novo,vocêpode confundir OPAM (porque os diretórios _opamnão são relocáveis).
  
  Did you copy ~/tezos to ~/tezos-new without cleaning-up the build-artifacts? If there is an `_opam` subdirectory in ~/tezos and you try to copy it to ~/tezos-new you may confuse opam (because the _opam directories are not relocatable).
